Cannot get rid of cyano!

[NU-2reef]

Chemi clean is an antibacterial and will kill Cyanobacteria but will also kill good beneficial bacteria. Which can cause an imbalance in the tanks biofiltration and in severe cases cause tanks to crash. I like many others have had success using it and I would recommend this as a last resort. (just before you feel like pulling your hair out).

It will not release the nutrients back into your system it just breaks it down so it can be pulled by the skimmer as dead waste.

i havent read through all of this thread but i read that ro water still contains silicates
which are needed by the cyano to grow. id google what to do to remove silicates from your ro water. the product chemiclean mentioned above i have used and it is a great product removing the cyano and the grunge from glass and equipment also but you have to be prepared to do a large water change after. the skimmer will run way too wet (virtually unuseable) until you to the water change so and bubbler will be needed. just my 2 cents worth

I was sceptical using chemi clean. But after a loosing battle I took that route. Worked great. And has not been back.
Just be prepared for some water changes after. It took three wc before my skimmer was back to normal

Btw. Rowaphos removes silicates

I run a sulphur denitrator that is controlled with an ORP controller and had it running while I dosed chemiclean, the denitrator functioned properly the whole time, therefore, the chemiclean did not kill the good bacteria in the reactor so I dought it killed the good bacteria in my tank.
The package says it is safe and after using it I have to agree, I so absolutely no ill effects other than a whacked out skimmer.

I've used chemi-clean in tanks up to 2500 gallons multiple times, and never once has a tank crashed......

No screwing around, 100% recommend chemi-clean; all of the site sponsors carry it, do yourself a favour ( OP ) and save yourself the time; try it out.
