Freshwater Aquarium Pike Fish

Keeping the tank clean helps to keep down the level of toxins in the water and helps the fish resist disease. Another important aspect to keeping any fish is to make sure you do not overload the tank a general rule of thumb is 1 inch of fish per gallon. So if you have a 20 gallon tank, it can safely house 20 inches of fish. The less fish the better, of course. Refrain from mixing your Siamese fighting fish with any other fish that like to nip at fins, and remember only 1 male per tank!

The water at the bottom of the filter is fresh and high in dissolved oxygen, so aerobic bacteria cultivate in the bottom half of the sand bed, and remove ammonia and nitrite, using up oxygen in the process. In taller fluidized-bed filters, enough aerobic bacteria cultivate in the bottom half so that as water flows past them, they remove most of the oxygen from the water, so facultative anaerobic bacteria cultivate in the top half of the sand bed where they remove nitrates. Not all fluidized-bed filters are tall enough to promote anaerobic denitrifying ba

He also used to test for nitrates, nitrites and phosphates, but stopped once everything was established and growing. He told me, "I can usually tell if something is wrong by looking at the fish/corals. If something seems amiss Ill run water quality tests until I find the problem. The animals seem to be the best indicators. I add Kent Tectra and use C-Balance once a week, a capful each. I used to use Kalkwasser for make-up, but in tanks so small, I dont really think it made any difference. Once in a while I will use Aragamite ."

Tom does water changes of about 25%, once a month. He u

Bucket!!!), and tries to keep his specific gravity around 1.022-.023 though he admits its hard to be exact in such small tanks. Because of salt creep, Tom usually ends up adding a little bit of salt to the make-up water. He notices that if the spg goes to low, the corals tend to react adversely. Temperature regulation

Because of this I rarely use them, but they do have a couple of interesting options that are worth mentioning.

These pumps can be purchased with a kit to use them in a reverse flow undergravel filter. In a conventional undergravel filter, water is pulled down through the gravel, under the filter plate, and up the lift tube. In this mode the beneficial bacteria in the substrate act as a biological filter, while the substrate itself acts as a crude mechanical filter as it traps dirt and debri

Mud sump
Hi, my husband is starting a new 170 gal tank with a 100 gal mud sump for me. Is it ok to take maybe a third of the mud from my 50 gal mud sump and use it like a sourdough starter? How long would it take for it to cycle? Thanks.
