Why are aquarium filters important?

A filter basically cleans the water of debris, removes the toxic buildup of ammonia and nitrates, and aerates the water so your fish can breathe. Sure, with very simple tanks, you can remove the fish, clean the tank, replace the water, then return the fish.

Why is it important to have a filter & replace the water periodically in freshwater aquariums?

Changing your fish’s water regularly is important because even if your tank water looks clear, particles of food and waste are still present. Not only does this cause a physical buildup, but waste converts into chemicals such as nitrate and phosphate.

How do I change the filter in my aquarium without losing bacteria?

Leaving the Old Filter in the Tank Keeping the old filter or cartridge in the tank along with the new one for four to six weeks is the most effective and easiest method to prevent bacteria loss. You just need to install the new one and remove the old one after a month or so.

Do filters remove ammonia?

Biological Filtration: A biological filter will convert toxic ammonia (from your fishes’ waste, excess food, decaying or dying plant mater, and dead fish) into Nitrite, and toxic Nitrite into Nitrate. Even the highest quality biological filters cannot process fish waste until they have properly cycled.

Do fish tanks with filters need cleaning?
