Thanks! I want to balance sps growth and swimming room with space/areas for the fish to find safety/security.
As for my DI resin, I have about 23ppm of it in my water, above 35 is high but anything above 0 hits the DI. What I did and is working better now is add a second DI. This is allowing me to completely deplete the resin in stage 1 before replacing it.
early results are better, I would have replaced the resin a while ago but with the second stage being there I’m letting it roll. For the past 100g it’s read 1ppm out and looks (color change) exhausted but until it’s showing the same tds out as in, it’s not completely exhausted!
