Lava rocks preventing PH drop?
Will regular lava rocks hinder me from lowering my PH? Could the
rocks be buffering my water. I have done 1 water change since first setup and will be doing 30% weekly with regular tap and conditioner.
I have a 240 Gallon with a 40G sump. I have a spraybar return with CO2 injected. Reactor is plummped through the return. I have no idea what my params yet since im waiting for my kit. Co2 is running. PH is constant at 7.8-8.0
I will be putting Peat Granules when i get it from Dr Forsters and Smith. Putting it in my sump. I have Eco Complete for substrate.
