Do (and How) They Work – API Quick Start VS Tetra SafeStart?

There’s an ongoing debate among fishkeepers about whether Tetra’s SafeStart or API’s Quick Start even work.

IF they do, which one is more efficient?

What is the difference between Tetra SafeStart and Tetra SafeStart Plus anyway?

Starting a new tank can be stressful for both you and your new fish buddies.

The logic behind these products is solid, but that’s in theory.

Is there a safe dose or an overdose?

Should you do a fishless cycle?

What’s the reality? The good news is I have tested them both…twice.

I’d be more than happy to show you my results and point you in the right direction.

Shall we?

Which one to choose if any – API Quick Start versus Tetra SafeStart?

Both products claim to have live nitrifying bacteria that will speed up or reinforce your nitrogen cycle.

They contain two sets of bacteria stains – one that turns the ammonia into nitrites and one that turns said nitrites into harmless nitrates.

Here’s the truth about the Tetra SafeStart vs API Quick Start comparison:

Both Tetra Safe Start and API Quick Start will work, given that they are applied in a correct manner. The cycling of a new tank will speed up significantly but it won’t happen overnight.

You can realistically expect a fully cycled tank at the end of the second week (10 to 14 days) after application. Dosage plays a major role in success.

However, following the instructions on the back is not something that will help, as they are pretty vague.

It is rather inconvenient that the instructions on both are not helpful.

After experimenting hard I’ve managed to highlight what strengthens your chance for success, eventually finding a process that, in my opinion, is foolproof.

I ran two tests on both before actually using them in a real fish tank project.

The only disappointing part is that they will not cycle your fish tank the same day.

Also by “add fish instantly” they don’t mean all of your fish.

How to use them and make them work?

After running a couple of tests I am confident to share my success formula with you.

Going through hundreds of forum threads and speaking with fishkeepers I know, I did find confirmations of my findings.

This means that my logic was correct.

Firstly you’d need to get the right bottle of bacteria.

Safe Start and Quick Start both contain live bacteria.

Both brands are claiming no refrigeration is needed.

The perfect temperature for the bacteria’s shelf and in-water life would be between 40°F and 80°F (5°C to 25°C).

Going beneath or above that range may spoil it, killing the microorganisms rendering the product useless.

Trusting your local fish store is okay, but I do prefer getting mine over Amazon (link to them, that will open in a new tab) as they really know how to ship them properly and in the right conditions.

If you do insist on getting it from your local market make sure that they were safely stored and aim to get the most recently shipped ones (with the farthest expiration date).

Some instructions before you start are:

  • Get a bottle that has been manufactured as recently as possible – The newer the bottle, the better. Also, get at least two bottles, I will explain why later.
  • Choose a bottle meant for a larger aquarium than yours – For me, it worked best when I used the 8.45 Oz bottle of Tetra SafeStart for my 55 gallons, and also when I doubled the dose recommended for the API Quick Start.
  • Make sure the ammonia is not already deadly high – everything above 2.5 ppm of ammonia will be harmful to your fish AND the bacteria. Before you start with the nitrogen cycle you need the ammonia lowered as much as possible.

With that out of the way, you can start recycling your fish tank.

Follow these exact steps to properly use Tetra SafeStart or API Quick Start:

  1. Dechlorinate your water no less than 24 hours before adding the bacteria.

    Use a dechlorinator.

    Leave the filters running during that time.

    Chlorine will kill the not well-established cycling bacteria.

  2. Shake the bottle of bacteria hard.

    This part is really important.

    Shake the bottle really well before adding the bacteria.

  3. Pour in double the recommended dosage.

    For Tetra users just add the WHOLE bottle of bacteria to your aquarium.

    Add it all.

    It’s beneficial bacteria. The more the better.

  4. Add 1 SMALL fish per 10 gallons of water.

    This should be done shortly after you’ve poured in the bacteria, within a maximum of 2 hours.

    The proportion is what worked best for me.

    By definition, this is where most people make a mistake.

    Adding a fish per 10 gallons of water is the safest way of controlling the ammonia levels.

    It’s true that you can stock the tank up, but you’d need very clean fish (ones that do not poop as much) and you’d have to feed them very carefully to either not overfeed (leaving extra ammonia work for your bacteria) or starve them (being too cautious not to overload your tank with ammonia).

  5. Feed your fish every other day.

    Test your water frequently, if you notice a spike in ammonia it’s okay to not feed your fish that day.

    Many fish can survive more than a week without food, so they will be fine.

  6. Don’t do water changes until the 14th day.

    If and only if the ammonia starts rising for no apparent reason you can do a water change to lower the levels down.

    Add another bottle of the product if that happens.

    This is why I told you to get a second bottle.

    On the 14th day, you can safely do a water change without harming the bacteria as it should be already established in your filters.

  7. Don’t test the water for the first 2 days.

    It’s okay to test it whenever you want but that is something that I stuck to throughout my tests.

  8. Turn the UV lights off for the first day or two.

    Ultraviolet light does affect the bacteria in a negative way.

    For it to successfully establish I’d strongly recommend avoiding to turn those lights on the first day after the application.

  9. Do not dechlorinate for at least 10 days after use.

    The bacteria come in an ammonia solution as that’s what it needs to feed and stay alive.

    Every product that claims to lock the ammonia out likely transform it into ammonium.

    This chemical bond is harmless to bacteria and fish alike, but the detoxifying only lasts for 24 to 48 hours.

    After that, the ammonia becomes toxic again and it may overwhelm your bacteria.

    However, the way more important factor here is that you’re probably using tap water for your fish tank.

    Water facilities in the more developed cities use Chloramine instead of Chlorine for disinfection.

    Chloramine represents the chemical bond of chlorine + ammonia.

    Seachem Primer, for example, takes care of the chloramine and detoxifies the ammonia.

    However, the effect expires in 24 hours and now you have even MORE ammonia in the cycling aquarium (released by breaking the Chloramine bonds).

    This can easily turn into a vicious circle and a never-ending supply of Prime for the fish tank of the inexperienced fishkeeper…

    If you’re using bottled baceria you’d want your tank to cycle as soon as possible, right?

    After the 10th day, you can dechlorinate.

Keeping the fish tank cycled

After the second week you can gradually add fish, but of course, don’t add 10 at a time.

When doing the first water change the ammonia will go up, as there is ammonia in tap water, but I wouldn’t worry about it that much.

The levels should be quickly back to normal within the next 12 hours or so.

Don’t freak out if you don’t see your nitrites spike when water testing.

If you’re using Tetra’s SafeStart the process will skip the nitrites building up and will directly build into nitrates.

Don’t worry if your aquarium becomes cloudy at first.

The water will get clear within two to three days.

Which one to choose? What’s the difference?

This is not one of those posts where I discuss the pros and cons of both products and leave the choice to you.

I have a statement:

Both can be (successfully) used for a start but If you’re starting a brand new empty tank and want to establish an ammonia safe environment I’d recommend using Tetra SafeStart.

If you’re starting a brand new planted tank, doing huge water changes or adding a lot of fish at once to an already cycled planted tank I’d go for API Quick Start.

Tetra’s better at handling the nitrites (it virtually skips them) and API will normalize your ammonia levels quicker, which in an ongoing aquarium is more important.

High ammonia levels may result in your fish staying at the bottom of the tank seemingly gasping in despair (click the link for an in-depth explanation of this behavior in Bettas).

The API Quick Start is more efficient when you have a planted tank as it does not handle the nitrite levels as well as Tetra’s SafeStart.

Note: Between Tetra SafeStart and Tetra SafeStart Plus the difference is only in the concentration of the bacteria. I’m really happy with Using the Plus version, so the instructions will remain the same.

The saltwater alternative is called Bio Spira.

API doesn’t have a saltwater version, you just double the dose.

What’s with the mixed opinions then?

Honestly, it’s probably human error.

Seeing how (upon proper use) the products kept prooving themselves to me and others I spoke to, I can only conclude that.

Then again, the negative reviews pushed me to test them myself, before anything.

Conclusion

Fishkeeping is a patient hobby.

Whether you choose to go natural or use a product on starting a fish tank, you will have to wait it out a bit.

There is no shortcut for that, there are only shorter cuts…

Thank you so much for this article! I’ve read it probably twenty times in the last two months. I received a new (and extremely tiny) 1.6 gallon fish tank and a betta as a birthday present back in March. Not knowing anything, and given poor advice from the pet store, the poor little guy died in 8 days from new tank syndrome. I was determined then to do a fishless cycle, and tried from March to the end of May with absolutely no results. I decided to try again in June using a hardier fish (I got a Panda Molly)… Read more »

Thank you for testing these products! I got my first Betta (Buddy, and he’s the coolest, spunkiest little thing) almost a year ago. The poor guy has been through a lot, mostly because his mom travels and falls a little behind on water changes. He also went through a significant relocation that sent him into a bit of a depression which I believe led to some fin rot. He’s overcome that, and now I’m worried he has Popeye, or maybe it’s just a weird growth on his face (I have no idea who I can even consult for something like… Read more »

Thank you for this post! After reading this I decided I would use safestart to cycle my new 75 gallon aquarium. I followed the directions exactly and (against all advice) started off with 6 Neon Tetras. I tested at 3 days and 5 days just because…. 0,0,0. Been feeding lightly… kind of surprised at 0 readings but I guess if Nitrates slowly build towards the 14 day mark that be good(?) the tank is well filtered, non-planted, fish seem happy (I will update regarding the Neon Tetras as well). I will wait patiently… anything else I should watch for?

Hey there! I got sort of thrown into fishkeeping with a platy brought to a gift exchange (live animals make terrible gifts but try telling that to this guy…). I’ve had the platy in a 10 gallon planted tank for 2-2.5 weeks now. I’ve done a few water changes in that time (about 30%). I’ve been dosing with API QuickStart as the bottle recommends. Just now tested the water for the first time (I didn’t order a test kit until I learned I needed one a week ago—there’s definitely a learning curve in fishkeeping!) and pH is about 7.5, ammonia… Read more »

Thanks for the info. I recently got a 50 gallon aquarium after about 15 years of not having one.
I followed your instructions, used the tetra tap water dechlorinator and tetea plus. Gradually added some tetra and danio glofish. Did a25% water change 3 weeks later. 2 months later I have 6 of each and 2 catfish. They are schooling, happy, and healthy.

Researching the do’s and don’ts of fishkeeping is like trying to figure out which weather man to believe. Very aggravating. :\ I started up my 46gal bow front 4 weeks ago, added fish a week later… four Rosboras (two are very young and small), a small DoJo Loach, and a Rainbow. I only learned of fishless cycling after purchasing my fish and wish I would have went that route as my Rainbow died from the ammonia not even a week after purchase.

Hi, I started a new tank 10 gallon. I started it about a week and a half ago. All the levels are great and I’m getting fish tomorrow. My question is Should I add the whole bottle of safestart plus or the recommended dosage for adding new fish. When I started the tank I put safestart in, but have since added conditioner. I wanted to add the safestart plus to prevent new tank syndrome and to filter the bacteria. I’m not sure if I should add all or not. Thank you! Anna

Found your article and thought it was well written. Thanks for sharing your experience with the two products. I got the TSS+ 3oz bottle and emptied it into my 32G tank. The bottle said can use whole bottle up to 40g tank. Per your recommendation, I doubled it by adding another bottle the next day (yesterday). Prior to this, I had used Seachem Stability (which worked well in my other smaller tanks), and the LFS recommended using Nitromax so I did that too. The levels haven’t shifted from pH @ 8.0, ammonia @1.0, and nitrites and nitrates are still @0.… Read more »

Also, should mention we have the white film / on the spider wood in the tank but from what everyone has told me, that’s normal, harmless and should go away by itself in a couple of weeks. But not sure if it affects the tank cycling.

Hello! I’m about to start a new 6.8-gallon tank for a betta, and I was hoping the Quick Start product might help shorten the cycling time. It looks like it may well do that! My question is this: Can I use fish food as the ammonia source instead of a fish? That was my plan when I was looking at natural cycling, and I’m wondering if it might still work with the added product. Thanks for this great info!

Hello! I came across this article after I added the API Quick Start to my (currently fishless) 20 Gallon tank. I added the amount it said on the bottle (20ml) and the dechlorinator at the same time. I see now that I did that wrong. My question is, should I wait 24 hours and add another dose to double it then add a couple of small fish, or I’d there a better way to do it?
Thank you for all your advice

Thanks for the detailed guide. I used Tetra Safestart recently in my 15 gallon freshwater tank, but have been doing a fishless cycle by dosing ammonia whenever it drops below .5 ppm. Yesterday, I dosed 3 ppm of ammonia, and tested today after 24 hours. A good sign: my ammonia dropped to 0, but my nitrites are seemingly off the charts (5ppm or even higher)! I have a lot of nitrates as well (40 ppm). I don’t know if you have an answer for me, but my question is: Shouldn’t I have no nitrites because Tetra Safestart practically skips that… Read more »

Thank you so much for this guide, I’ve had my planted tank for year with no fish inside because of a nonexistant fishless cycling process that just refused to move!
Yesterday I started the cycle for my 10 gallon with Tetra SafeStart Plus and one endler guppy. I also have Quickstart so I added some of that as well because we had a cold rainy day when my TSS+ showed up and I got paranoid that the bacteria got too cold in the mailbox.
Fingers crossed everything goes well! My new friend seems very lively and healthy so far 🙂

Hi, so I want to start using TSS+ after making a mistake of listening to the pet store workers with the Top Fin Bacteria Supplement. Because I currently have water in the tank, should I do a water change now to start over (empty the tank)? In addition, for TSS+ 3.38 fl oz. bottle, do I add the entire thing to my 10 gallon tank?
