Hi guys, On thursday I did a 50L water change on my 400L system and on Sunday I put in a DSB using playsand that I washed properly (15cm). Straight after the water change on Thursday all my corals closed and they still look closed/weak. Must I give it time? And one more thing I bought 2 sand sifting starfish Saturday. The one is moving and going under the sand but the other one is on the sand and he has only lifted his arms now and then... is he dying? My fish are like always
Thanx in advance
