Cyano outbreak

slipknotgrrl83 · Aug 17, 2016

I am getting a bit of cyano on my rocks..not alot but would like to do something before it gets worse. Here are my specs

Nitrite 0
Nitrate 0-1
Ammonia 0
PH 8.1
Cal 500
Alk 10
Mag 1400
Phosphate about 0.05

Tank is 3 years old, I only feed Frozen once a day and have sump with skimmer, lots of live rock and led lighting only run 8 hours a day.

I have been pulling it off rocks, glass, substrate but it comes back. I know there is a chemiclean product but not sure about it since I have a lot of corals like duncans, goni, hammers, bubble, mushroom, favia etc. Any thoughts or advice?

I just did chemiclean in my tank two weeks ago and it works great. This is my 3 time I've done chemiclean in my tank and I've had my tank for almost 5 years. It works great just make sure you take a turkey baster and blow as much cyano you can off the rocks and sand. And keep your flow high and then add the chemi clean. Of course turn off any skimmers, uv sterilizer a, remove any carbon or gfo or anything. 72 hours I believe and then do a 20% water change.

So water change blow off excess cyano and remove then add chemiclean for 72 hours, skimmer off. That's my only form of " filtration" other than LR that will hopefully be fine , I don't have heavy biology. Then do water change after the 72 hours. No signs of coral or fish/ invert harm?

Won't harm invertebrates or coral. At least in my experience and what it says on the packaging. It may lightly stress some corals but you should be fine. Cyano will do more harm then chemiclean ever would. Like I said. Turn off skimmer, blow off any cyano off the rocks and on the sand. Make sure it's all off the rocks I've found this way to work for me. Mix the chemiclean in a cup of tank water and place in it a high flow area like where your return is. You can also place some where your circulation pumps are so it disperses well. I will add after the 72 hours after you have done a water change I add carbon to help remove any of that chemiclean left in the tank it does help. And the skimmer will go crazy and overflow for a week or two mine just got back to normal yesterday but it's fine now.
