I’ll start by explaining what’s happening in my tank, I’ve noticed I’ve been getting ammonia, it’s been set up for around 4 months already and was cycled, but I raised my co2 levels to try to get a lighter green on my co2 level indicator since my tank is heavily planted, one of the times I tested my water the ph seemed to be around 5.5 according to the colors on the tests, This is obviously too low so I’m thinking this is killing the beneficial bacteria that turns ammonia into nitrates, my question is, for those of you who keep co2 levels around 30ppm, how do you keep your ph from getting too low? I don’t want my gh to be too high, I think a high gh would make a higher ph but I want a low gh around 4 and good co2 levels without the crazy acidic PH.
