What pH should the water be for tropical fish?

Most tropical fish prefer a slightly acidic to neutral pH range between 6.5 and 7.5. However, the specific pH requirement can vary depending on the species of tropical fish you are keeping. It is important to research the specific pH requirements of the fish you are keeping to ensure they thrive in their environment.


A student measuring the pH of the water in a fish tank found it to have a pH of 8 what is true regarding that solution?

A pH of 8 indicates that the water in the fish tank is slightly basic. This pH level is suitable for most freshwater fish, as they typically thrive in a range between 6.5 to 8.5. However, it is important to monitor the pH regularly to ensure it remains stable for the health of the fish.


What is acidity for tropical fish?

The acidity for tropical fish? I think your referring to the acidity of the water in their aquarium...??? Generally, "tropical fish" do well with a neutral (7.0) or slightly acidic (6.7-6.9) PH level in the water of the tank. This is easy to test using a PH test kit from your pet store. The acidity of the water is affected by whatever is IN the water with the fish---in the wild, the flora and fauna of the area dictates the PH (acid-neutral-alkaline) of the water. In general most of the common tropical fish (freshwater) sold in pet stores come originally from central/south America and Asia. The waters in these areas are slightly to mid level acidic depending on the time of year. These fish would be the common "community" tropical fish like tetras, gourami's, live bearers (guppies, mollies etc) and algae eaters/scavengers. The larger "cichlids" like Oscars, Jack Dempsy's etc are also from South America but are aggressive. All do fine with an PH (acidity of 6.8-7.0) as most are commercially raised now anyway. Don't put "wild" rocks in your tank as they could contain pollutants and be very calcium rich (like sea shells) and raise the PH to above 7.0 into the Alkaline level. Some fish (like the African Cichlids) prefer a high alkaline environment... Hope this helped, Jason


At what pH would the enzyme be most effective?

It depends on what type of Enzyme. Enzymes have different optimum pH depending on the environment they work in, for example and enzyme in the stomach of a human would have a pH of about 2 but an enzyme in human saliva has an optimum pH of 5.6.


What effect does acid rain have on fish?

The pH scale runs from 0 to 14, with 0 being extremely acid and 14 being extremely basic (alkaline). Water with a pH 7 is dead neutral. This is a suitable pH for keeping most tropical fish. If your pH of your water is less than 6.8, it is considered acid water. Fish suitable for acid water include apistogramma dwarf cichlids, angelfish, discus, tetras, gouramis, rasboras, danios, many catfish and barbs. If your pH is more than 7.4 it is considered alkaline. Suitable species for this water include kribensis, some other cichlids, rainbowfish, livebearers (guppies, mollies, platys and swordtails) most barbs and most catfish. Some water is very alkaline, with a pH of over 8. This is generally suitable only for fish that have adapted to survive in these conditions, such as African cichlids - but these are large and demanding, so do plenty of research before you buy a tank for them.

Lower numbers are more acidic. The normal range for pH is 0-14. However, it's possible to go beyond that range (2M HCl has a negative pH); I'm not certain what the absolute lowest (or highest) possible value is.
