## Getting equipment according to the dimensions of the aquarium?

Selecting equipment based on the size of your aquarium is essential for its long-term success.

For one, the dimensions of a fish tank play a huge role in the choice of aquarium lighting because light itself has a limited water penetration.

by tomas10024

If you’re in the middle of your research on choosing a suitable light fixture for your aquarium plants you can check my guide on that here. In that link, I do specific product recommendations based on aquarium depth and the type of plants you may want to keep.

The same rules apply for picking adequate grow lights for saltwater reef aquariums. Corals are very sensitive to the intensity and spectrum of the incoming light they use for photosynthesis.

To end up with the right LED light you’ll need to take into account the dimensions of your coral reef aquarium. There are stronger units that penetrate the water well and are suitable for deeper reef tanks and others that are less intense, making a good addition to aquariums with less demanding corals. I made specific recommendations on choosing the best LED lights for corals based on aquarium height and the species you want to keep. Visit the link to learn more.

Choosing the flow rate of a water filter should also be made in conjunction with the gallon capacity of the fish tank. If you keep larger carnivorous fish that produce more waste or you plan to overstock the tank you’d want a stronger filter that turns the water at least 6 times per hour.

For Oscar or Cichlid fish tanks getting an external canister filter makes perfect sense as these units produce more flow and have enormous space for media, which in turn keeps the aquarium clean and safe. I have an article on choosing one according to your aquarium’s gallon capacity (visit the link to learn how to make a choice).

If you want to keep aquatic turtles you should still take into consideration the available water volume in the aquarium. In this case, you can check my article on picking a good filter for a turtle aquarium according to gallon capacity. Turtles are messier than most aquatic pets and require a water turn over of at least 8 times the whole aquarium’s gallon capacity per hour.

On another note, a small 3-gallon, 5-gallon, or 10-gallon tank with tropical fish requires a small-sized aquarium heater that’s ideally under 6.5 inches in length. I’ve seen enough small aquariums with a spoiled interior because the owner got an over-sized heater.

And last but not least, the gallon capacity of your reef tank, for example, plays a major role in your choice of aquarium wavemaker. You can check my guide on how to make the correct choice by clicking here.

Knowing the exact dimensions of your new fish tank will give you the needed information to make adequate decisions on choosing livestock and the purchase of equipment. Drop me a comment below if you have any questions in those areas and I will answer as soon as I see it.

I have been looking high and low for a air pump that will be sufficient for my needs but is quiet and doesn’t get hot. Would like to know if the Fluval Q2 is a good choice and if it will be strong enough to run several 18″ air bars in the bottom of my soon to be standard size 120 gallon. I will be upgrading and I haven’t even be able to find one strong enough for my 55 gallon. Any help would be great.

Have a 10inches in height 10inches in width and 12inches dept dont know what gallon it is? Help

Hi, that would be a 5-gallon tank.

The formula is as follows:

10 inches = 0.83 Feet

12 inches = 1 Foot

(Lenght x Width x Depth) in feet = 0.6889 Cubic Feet.

Cubic ft x 7.47 = 5.15 Gallons.

I have an aquarium that is 48″x 12″ x 31″ which is about 75 gallons. I am just wondering if you might know who it is made by? I can’t find any information about a tank with these dimensions.

Thank you.

My tank is a 30×12×12 is that consider a 20 gallon

In my calculations, that’s a little over 18 gallons.

I don’t have the slightest idea of where to begin with this tank! This is all new to me. From your cheat sheet I am guessing I have a 29 gallon tank. I’m confused though as to which 29 gallon tank I have because you have different types of tanks listed. The tank was given to me. Once I figure this part out then maybe I can figure out where to go from there lol. Help please!

Hi Denise,

Could you measure its dimensions? This will help in figuring out which one you have.

From there on, you just need to equip it with the right filter / lighting according to the tank’s size and the setup you’d want to achieve (e.g. heavily planted, non-planted, lots of fish, etc.).

Best,

Momchil

Great information! Thank you for the article.

Thank you TKP!
