Can you use a salt water fish tank filtration in a fresh water fish tank?

Answer 1

The type of filtration greatly depends on the size of your tank. I would in any case recommend a wet/dry "sump" filter. It will increase your total tank water volume. If that is out of the question I would not go for anything less than a canister filter. Salwater aquarium supplies and equipment can be expensive but i wouldn't do anything less. I have tried taking the penny pincher approach to filtration but ended up with a tank of dead fish (very expensive fish). Make sure to cycle your tank completley before adding fish. Nitrates WILL kill your fish. good luck!

Answer 2

No. You need to use RO (reverse osmosis) water. Most pet stores that have saltwater supplies sell it between .50 and .75 a gallon. If you can't get the RO water, you can use distilled water from the grocery store.

Answer 3

The water composition in two environment is largely different (different minerals) and so, while a specie of fish can adapt to salt water, it may not necessary be able to adapt to fresh water since they can't pull out the same type of mineral to live in different waters.

Some fish however, can live in both environments (salmon)

So no, MOST of the fish is NOT able to live in different water environments

Answer 4

That depends on the filter, but in general you can.

Most tank filters are simply designed to remove debris suspended in the water.

Many have activated carbon as well to absorb smaller impurities that would not be trapped in any filter.

Some filters are designed for salter fish or for reef tanks.

However, a freshwater filter will work, but it may not be the best filter for the tank.

Answer 5

Provided it has been cleaned out properly there is no logical reason why it should not be perfectly good working on a fresh water tank.

Answer 6

Yes, you can find them where they sell salt water fish.
