You cannot have too much filtration but you can have too much current. If your fish are being blown around the tank or if they are always hiding in eddies, then you have too much current. GPH is not the most important aspect of filtration. Volume of biomedia is.

Can a strong filter kill fish?

The answer is yes, but not because water changes are inherently bad. The cause is more complex than that. Over time the by-products of fish waste, uneaten food particles, dead leaves from plants, etc., alter the chemistry of the water.

How often do you change the filter on a fish tank?

A quick rinse in tank water will clean it without killing off too many bacteria. Also, think about having multiple foam filters and cleaning or replacing one at a time to minimize the impact. A lot of the filter cartridges recommend changing once a month. This is generally a result of them containing carbon.

Are two filters better than one?

It is true that if you use more than one filter on your fish tank, neither of those filters will perform as efficiently as it would if it were the only filter on the aquarium. Each filter is less efficient because of some of the restrictions placed on filtration systems by water volume and surface area.

Can you over oxygenate a fish tank?

Actually you can. It’s caused oxygen supersaturation. It can cause what’s known as air bubble disease, which means that air bubbles form inside the fish (including eyes and organs) and will cause great pain. You know you’re oversaturated if small bubbles stick to the fish and ornaments.

How do I know if my fish filter is too strong?

You should check to see if your betta is swimming with ease. When the current in your tank is too strong, your betta may look like he’s struggling to swim. It almost looks like he’s getting blown around in the wind.

Should I keep my aquarium filter on all the time?

Filters need to be kept on at all times to remain effective. The most important part of the filter is the bacteria that lives in it and breaks down the ammonia that the fish produce. Without this bacteria, the aquarium would require fresh water every few days to prevent ammonia related illness.

Do you turn off filter when feeding fish?

If your filter is pushing water downwards then it can be a good idea to switch the filter off during feeding to prevent this — just be sure to switch it on again afterwards! It might also be worth considering feeding in smaller quantities so the fish can gobble up most of the food before it reaches the bottom.

Will my fish die if I turn off the filter?

The problem with turning off the filter isn’t that the ammonia and wastes will build up to toxic levels overnight, it is rather that (according to some) if you turn your filter off overnight you will kill the bacteria in your filter. Your tank will cycle all over again, ammonia will build up and your fish will die.

How do you keep fish away from filters?

First, and best option: get an adjustable filter, that allows you to turn down the flow. The fish get stuck because they are small and the filter is too strong. Second option: put a prefilter sponge on the intake to protect the fish from getting sucked in.

How long does a fish tank filter last?

Chemical filtration uses activated carbon to absorb chemicals from the water. The carbon filter must be changed about every two weeks.

Can you do a full water change on a fish tank?

There are two types of water changes for an aquarium: the partial and the complete change. The complete change, you will change all the water in your fish tank with new water. The partial change, you will only change a partial amount of the water in your tank, normally it is about 10 to 15% would be changed.

How long should my aquarium filter be on?

Operating time of a filter, how long must run a filter. A filter should work continuously all day, 24 hours on 24 except when cleaning. If a filter is stopped it is no more oxygenated, and there is risk of bacteria asphyxiation, the filter could then create pollution.
