Hey all,
So, I'm wondering does dosing EI (using Pfertz N,P,K and Flourish Comp) raise your KH and GH?
I have a 6gal Fluval Edge, and I do weekly 50% water changes with RO water. Before my water change, my readings were KH-7, GH-11. One day after the water change, my readings are KH-7, GH-9.
I do have Seriyu stones in the tank, and have high CO2 (yellow drop checker). I understand this will raise KH, but I don't believe it should raise it so quickly, and that does nothing to explain the rise in GH.
Any ideas? :help:
