Thank you. I'm a bit hesitant about using Excel because I remember reading somewhere that it has some effect on the shrimps as well. Because this tank is a high grade CRS tank with some babies, I think I will do some heavy water change first to see if it helps.
Currently I have Crystal Red, Crystal Black, Golden/White Bee, Blue Bee, Fire Red, Dark Green, Babaulti Green, Snowball, Fire Red and Unidentified Shrimps for sale. PM me for details.
