If you never owned an aquarium before, buying a 20 gallon fish tank would be a great place to start. As an aquarium size to start on, it’s neither too large for to maintain nor too small that you should have trouble really enjoying how beautiful an aquarium can be.
About the most important thing you need to get a handle on when you own a fish tank (a 20 gallon fish tank or any other) is this: water quality management is vital. No matter how much you invest in the fish or the landscaping, it’ll all come to naught if you aren’t on top of the water quality.
You’re probably telling yourself that has to be quite easy keep a fish tank clean. All you have to do is empty everything out once in a while and clean it out with soap, right? Well, soap would be exactly the wrong thing to use. As would chlorine or bleach. You have to remember that even a 20 gallon fish tank is pretty small. Any chemical residue from cleaning stuff that you bring to the tank could easily burn the fishes’ eyes. To merely clean well with soft scrubbing pad would be enough. And then you have to make sure you rinse the tank thoroughly.
You can’t go with tap water to fill your 20 gallon fish tank. That happens to be chlorinated water often, and it could be bad for the fish just the way chlorinated swimming pool water is irritating to your skin and eyes often.
It would be a great way to go about maintaining the water quality in your 20 gallon fish tank to use a great filtration system. If you have a water filter at home for your drinking water, you’ll find that they always claim to use a multistage filtration system. You want to do the same thing more or less, for you fish.
A multistage filtration system will put the water in your fish tank through a thorough scrubbing process to clean it right up. The first part of the filtration system is a sponge filter. Water passes through a biological sponge that absorbs ammonia and nitrate waste. Both of these are chemicals found in fishes’ bodily waste and can really poison the water if you don’t filter with biological sponge.
The next stage of the filtration process is a chemical one. You need to pass the water through a zeolite compound to further help clean the water up. And then, comes the mechanical cleaning process.
