Yup title says it all. The sand clouds my water. Every night with the lights off my dats have fun stiring up the sand. I know why they are doing it, one is making his hide out a little deeper under the driftwood. SO I'm not mad about it, just regret using sand because it seems to really never settle down. I probably should have cleaned it better then I did, but come on now it's been well over a month and the sand is still creating major dust clouds in the water. I'm ready to move out all the fish and take the sand out.
