Heyya folks. I'm having some problems with my SeaClone 100. I had it set up for a few weeks, then decided to recycle and replace the arogonite with sand. Before, it skimmed just fine, with plenty of froth. Now, I can barely get anything. I suppose that there probably isn't as much detrius and such as before, but my nitrites are sky high. Any suggestions? I have it set to lots of small bubbles.
