When I first set up my peacock/hap tank I was buffering the water to match, at least as close as I could, the ph and hardness of Lake Malawi. For the last few months I've stopped doing that, letting the water get to my tap water levels, PH of around 7.6, and hardness quite a bit lower. Ever since then, the green algae has gotten a bit worse. Could the lower levels be advantageous for the algae, increasing it's growth? Wondering if I should start buffering again.
