jestep Posted November 12, 2013 Share Posted November 12, 2013 Chemiclean has always worked for me. How is your tank setup, are you running biopellets or dosing carbon or have a very high stocking load? There have been basically 3 causes of cyano that I've experienced, outside of it being a normal phase in the first year of establishing a tank. While chemiclean might get rid of it, it's not treating the problem, just the symptom. Poor water conditions caused by overstocking, overfeeding, lack of maintenance, or if you have bad rock or sand that's leaching a ton of PO4. Incorrect NO3 to PO4 ratios. Would typically occur with use of biopellets or vodka or other carbon dosing without the ability to remove PO4. Old or bad quality lightbulbs or inappropriate lighting schedule.

Timfish Posted November 12, 2013 Share Posted November 12, 2013 How old is your system? Cyano should be expected during the maturing process (not to be confused with cycling) and usually disappears on it's own. On a somewhat separate note whenever I use chemiclean I do a large water change first trying to remove as much cyano as possible. Then I treat with chemiclean and do a 25% water change as specified. I've never had a problem with corals with this technique. Quote Link to comment Share on other sites More sharing options...
Bpb Posted November 13, 2013 Share Posted November 13, 2013 3 day complete blackout totally wiped it out for me...but that just freed up nutrients for something worse to bloom (dinoflagellates). Those were much harder to eradicate. Funny though. Few months ago I replaced a substantial percentage of my liverock with bleached, acid dipped, dried, then cycled rock and my 2 year old tank is going through the new tank algae phases. First was diatoms, now cyano. I run gfo and carbon and don't over feed. Difference is this time I'm not worried about it and know it'll pass. Don't panic it's just part of the process.

I did what Tim recommended above when I used Chemiclean on both my 180g and my Biocube29 and it worked great without adverse effects on my fish or coral. If you are worried about oxygen in the water, I would recommend running an air bubbler for the duration you have the Chemiclean in the system before your 25% water change at the end. I think this is more for your anxiety than really needed but it will definitely benefit the fish/corals as well. 1 Quote Link to comment Share on other sites More sharing options...
FarmerTy Posted November 13, 2013 Share Posted November 13, 2013 If you don't have an air bubbler but do have a skimmer, removing the collection cup and letting it bubble over works as well for aerating the water during the treatment.

Woods Posted November 13, 2013 Share Posted November 13, 2013 Ty is correct.. But I know when I used Chemiclean my skimmer went nuts creating extra wet skimmate. It caused my collection cup to over bubble and the popping bubbles made a mess in my stand.. Just a word of caution if you choose to use the skimmer without a collection cup, find a way to prevent the splatter mess that I encountered...

Gig 'em @ NDstructible Posted November 13, 2013 Share Posted November 13, 2013 I've always found that patience and proper maintenance and routine water changes always works. Add more biodiversity to the tank with critters and macro algae and that usually speeds up the process of finding a natural balance. 1 Quote Link to comment Share on other sites More sharing options...
FarmerTy Posted November 13, 2013 Share Posted November 13, 2013 Good catch Woods, my sump is wide enough that it caught most of the bubble popping splatter. If you have a tight setup, you may get the inside of your stand wet from all the popping bubbles. Quote Link to comment Share on other sites More sharing options...
Planeden Posted November 13, 2013 Share Posted November 13, 2013 i added air stones and my corals look no worse than they did before i used chemiclean. Quote Link to comment Share on other sites More sharing options...
