My PH is probably around 5. I did this with RO water and a buffering product. I would like to now start adding humic substances to the water. I came across a Blackwater extract product by Brightwell. It says it adds humic substances to the water. It says to remove the carbon when using it, as I would if using real peat moss. My question is, what do members here use for filters then without the carbon? I know in many things I’ve read, it is suggested to use a sponge filter, but are members using carbon too? What about the peat in the water? I just want the water to stay clean.
