what should the p h level be on a fish tank?

Answer 1

It depends on the fish you keep. For example, Malawi cichlids come from lake Malawi in Africa where the water is very hard, and has a high pH. If you have African cichlids, your pH should be around 8. On the other hand, Angelfish which are South American cichlids, come from a lower pH water, and should be around 6.5 pH.
Most community fish are quite adaptable to pH, even if it's not ideal. If your pH is between 6.5 and 8, it should be fine for most fish. Try not to mess around with pH - a stable but different pH is better than a fluctuating pH. For example, a fish that needs a pH if 6.5 if better off in a tank with pH of 7.5, than a pH that fluctuates from 6.5 to 7.0.

To know the exact requirements for your fish, google them :)

Answer 2

This depends on the type of fish you want to keep.

But in general I have recommend that you never mess with the pH of a fish tank. It is far more important to the fish to have a stable pH, even if it is not the ideal pH for the fish.

pH is very hard to adjust accurately and even hard to keep it at a particular level.

It's best to simply measure the pH of your tap water and then work with fish that can tolerate that pH level.

Answer 3

7

Answer 4

It depends on what type of fish you have. Generally is should be 6.8 to 7.2. Most fish will survive just fine in this pH even if it is different from their natural habitat, but they won't have the same coloring or behavior as they normally would. You need to research the type of fish you have to be sure--just go to yahoo and type in it's name.

Answer 5

Depends on the fish. 7 is generally good for most freshwater fish, but many fish do better in other ranges. A lot of tetras like acidic water down to 5.5 pH. While sailfin molly like 7.5-8.5 pH. (Black molly types prefer 7-7.8) While bettas, and most gourami are great in 6-8pH. (Not dwarfs who like 6-7.5.)

My advice is to test your water's pH, and kH then get fish based on you water chemistry. (Check the fish profiles at .liveaquaria.com.) Just keep in mind fish will often adjust to a wide range of pH, and kH.

Answer 6

I keep mine at 7. BUT you need to look up the fish you have because they may require a higher or lower PH.

Answer 7

Most fish will adapt to any steady Ph but each species does like a certain range. Tell us which fish you have and we will tell you what they like.

Answer 8

The optimum PH Level for fish is between 6.5 and 7.5.

For marine tropical fish, you want to keep it between 8.0 and 8.3.

For goldfish, 7.0.

Answer 9

7.0 is good for about all fish. 7.4 is dangerous for most tropical freshwater fish and 6.6 is also gangerous for tropical freshwater fish!(7.0 is nuetral andything higher is basic or akaline and anything below 7.0 is acidic)
