Is there a poll or articles about this subject?. I just can not keep my water clear. It is ok in the morning but as the day goes on everything turns to alka seltzer. I have one damsel that digs up everything all the time . I recently added 3 dotty backs to help rid the tank of bristle worms but they just dig and the wormes continue to multiply. My rocks look like pink rocks in motion at feeding time. I have been stung several times now and it takes weeks before the wounds heal completely. Is there a way to get rid of them? Thinking of going clean bottom and just livestock no more live PINK rocks. Will my fish live without the rocks? I know that my Mandarin will have to go.l Bubba
