About 10 days ago I changed my yellow neo / CRS tank substrate to fluval shrimp stratum and used RO water this past weekend for my water change. My kh is down to 2 and gh is 6. Ph is down to 6.6. Yesterday after feeding them mosura spinach from h4n (thanks again Han), I came home to at least 10 molts in the tank. I guess the shrimp are feeling at home. Now the waiting game begins. I want to thank everyone that gave me advice on my tank.
