Hi guys, I've helped a for end dial in their co2. But his water is softer than mine. Kh from the tap is 6. And by the time the aqua soil and co2 have affected it. The kh is sitting at 2-3. It's OK, when he's doing big water changes every day to replenish it. But long term you don't want to do it every day. Do you buffer you kh when it's low from the tap (mine is hard as nails). Also his drop checker is green again in the morning after water change. I take it because his water pH is low. But I'm thinking also maybe not enough surface agitation to blow off the co2 in the tank. Mine goes back to nearer blue by the morning. But his turns a darker shade of green between water change and the co2 coming in in the morning? Help required to check my thinking as I don't have personal experience of this. Thank you!!!
