Help Co2

[Webbie48]

I have purchased a pressurised Co2 unit JBL pro2
As the co2 will lower my PH in the tank, do you have to treat the water when doing a water change to make it the same level of PH as in the tank
My tap water come's in at 7.6
Cheers WEbbie

There are a couple of issues, both point towards a "no". First, unless you are doing really huge water changes in terms of percentage of the water replaced, the difference will not really do any harm. Second, is "treating" the water to make it match is going to either introduce chemical buffers which typically being phosphate based can trigger an algae explosion. Or is going to involve using RO water and building it up to the level you require which could be expensive.
