Over the last couple days my alk got low(6dkh). I slowly am bring it up over two days. My flame thrower and Immolotion orange are turing white. There flesh is fine and the are eating but there color is almost gone. They are both shaded. They are not getting to much light . They have been in the same spot for three months and been fine. What else do you guys and girls think in could be. My mag is 1320 if that helps any..
