what should be the ph level of water in tropical fish tank?

Question

i have tetras neons mollys thanks

Answer 1

Mollies like it from 7.0-7.8 ...

And Neon Tetras like it from 5.0-7.0 ...

So 7.0 would be good.

Answer 2

Your fish can tolerate a range of pH, so I'm not going to specify any particular value. You can check this link for more on the ranges: http://www.liveaquaria.com/product/categ.cfm?pcatid=830 , but the tetras would like it a little on the acidic side, and the mollies would prefer basic (above 7).

Since most fish have been captive bred, they no longer need as specific of a pH as is found in where they're from naturally. I would advise against using chemical buffers to try to alter your pH - these cause the pH to change over time, especially when you do water changes, and the fluctuation is more harmful to your fish than a constant value. There's also no way to predict how well they will work, or how much you'll need to add because they act against elements already in your water - the more you have, the more it takes to get the pH to change.

The best way to make sure that your pH is correct for your fish is to choose fish that are comfortable in the pH you have from your tapwater.

Answer 3

Well neons and molly's really like quite different water chemistry. So if you are going to keep them together find a happy medium. Neon tetras are best kept with a neutral ph.
(7.0) Your molly's prefer a higher ph around 7.7 or even higher. So 7.4 would probably suit both species.

Answer 4

ph is tricky. you really don't want to go messing with your water ph -- most fish will adapt to it. average and optimal for most fish is around 7.0. some like higher some like lower. tetras and mollies will do fine in low 7 ranges. mollies acutally prefer higher ranges than tetras. mollies do better in brackish water -- but that isn't an option with tetras.

Answer 5

Each species of fish has its own very narrow range of pH preference and levels outside of this range will cause health problems. For example, koi prefer a range between 7 and 8.5, while some tropical fish prefer water that is slightly acidic. (See first link for more details about pH)

The Neon tetra can live in acidic water as well as in a slightly alkaline environment, so anything from pH 5.5 to pH 7.5 will be okay. (See second link for more details)

Hope some of this helps - I learnt a lot!

Answer 6

don't be pre-serious approximately the quite pH point. presented it would not flow over 7.8 maximum fish species would be high quality. it is rapid pH variations that impact fish. have a glance on the article under and is the reason issues in extra element.

Answer 7

Ph around 8 is best

Hope this Helps !!!

Answer 8

pH neutral, 7-8, i think, erm..
many fish are very tolerant of higher levels, tropicals especially, because of the abundance of rotting vegetation in their natural habitats.

Answer 9

Ph around 7 is best

Hope this Helps !!!

Answer 10

7.0 to 8.0ph
ideally 7.4 to 7.6ph for tetras and livebearers (mollies)
