To save stress on my self and a lot of wet sleeves and floors for clam spitting I just started doesing my tank daily with 1 ml. per gal of dts and my clams are doing great and no algea blow to mention in the month and half I have been doing it, as a metter of fact there has not been a spot of troublsome algea since I started now that I think about it. This is a 37 gall tank so I only use lilke 5 ml. aday since there is only about 25 gall of water after rock sand.
This will be changing this weekend when they move to my upgraded 125 when I add the lights and new canopy. Then Dts will be disappaering alot faster from my LFS. Will jump up to arond 12 ml aday which I all ready started to get tank ready for clams.
