Ph Levels

[andyboy!!]

Hi

A few day's after doing a 25% water change - which I do every 2 weeks - my pH is at 7.0. How will this vary between the next water change. I know it will be influenced by fish numbers\plants etc, but is does in generally increase or decrease?

I have a 2 x 1 x 1 tank, with 4 live plants, 9 small fish and some rocks.

Cheers
Andy.

How much does your ph fluctuate? In general, i would increase the 25% water change to once a week instead of once every two weeks though if you can help it, if your ph is stable though i would not worry about it- such info is only really important to know when introducing new fish or keeping fragile/very sensitive ones or just making sure it stays stable over time .
