Tropica Aquasoil with RO water.
I will be setting up a new heavily planted aquarium shortly. I will be using Tropica Aquasoil as my substrate, and RO water (as my tap water is like liquid rock with high PH and Nitrate levels).
Apparently the Aquasoil reduces the PH of the water. As RO water has no buffering capacity, I would imagine that the PH would drop very low (maybe 5ish even). I assume that I should add minerals to the RO water to buffer against this so that the PH will not drop that low. Does anyone know what I should use to do this?
I have also posted this Title on to the Substrate forum as I am not sure which would be best for this problem.
