Getting equipment according to dimensions?

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.

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 fish tank’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 tank according to gallon size. 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.

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.
