So I've got this great 150g...The water out of my tap is a little bit messed up. It has an extremely high pH with a low hardness...after a little help from you all- we determined that my water co uses slated lime treatment and my water is deprived of CO2 out of the tap thus resulting in an abnormally high pH. So as long as it sits out for a day or so it absorbs ambiant CO2 and goes down to about 7.2 pH. So here's the future problem. I fill up my tank, let it sit for a day and the pH goes to normal, I cycle, etc. What's going to happen with my first water change? Even if I only do 20% thats 30 gallons! I don't have the room for aqing thirty gallons of water..and I guess the usefulness of my no spill python is cut in half. One though is that I have a press CO2 system with pH controler. If CO2 depletion is the problem maybe the adding of CO2 will compensate for the high temporary pH. Or will the addition of the high pH water freak out my fish. Man...I think I need some stress coat.
