Actually we're finding our trio of sea cukes are doing a tremendous job of cleaning up diatoms and such. When the lights go down they come to the front of the tank and clean the sand back to pure white... it looks so nice in the morning, but towards the end of the photo period it starts turning brown again and the cleaning begins.Originally Posted by jerryc
Not really a long term cure for the problem, but it is keeping things in check, that I know the cukes are definately eating good, they are getting HUGE!
