Thanks Keith. I was thinking I may not need to add much iron or any at all as my makeup water has about 2.5 ppm in it. How much iron do the plants need?
Ph and alkalinity is very high. Never had a problem with low ph with the fish. But never say never. Actually I was more concerned about lowering the ph to about 7.0 as a concession to the plants, fish, and bacteria.
I'm too lazy to do the media. Also like the additional water as a safety net for the fish with raft culture.
