[MENTION=5085]newtothis[/MENTION] Tanks great. I used stupid chemiclean on Tue last week as I noticed a small amount of cyano. I think I got it as the auto feeder spilled in. Anyways it worked but my conch snail has gone into hiding and I can't run my skimmer as it bubbles up, I even ran carbon, poly filter, and did multiple water changes. Can't wait to get the skimmer back online.
