Ok so I have a biocube 29 and everything is going good and all tank inhabitants seem happy and are growing. On to my issue. I have what looks like small grains of sand but after a couple weeks of watching they seem to be micro bubbles. Any thoughts on how to get ride of them or what could be causing them? also on the Algae I have the AL sol and if I turn just the whites on then my rocks are covered in a bright green and looks more of a brighter yellow brown when all three colors are on. Blues and whites. Any help I appreciate
