Take a pic please. The thing that shout at me is the nitrate reading of 20. They say that 10 is OK but I like mine to be 5. That suggests that more WCs are necessary. I'm suspicious of the Equilibrium and the Seachem buffers but I have to look them up and refresh my memory. Why are you not using aged tap? lA pH swing of 6.8 to 7.2 is what I have with my water and I found it necessary to age. I use no buffers, just aged tap 30% WC daily. I only use RO when I need to lower my TDS for a breeding pair.
