Didn't work for me.

Isn't working for me but I use it for the clarity.

Just removed my GFO and started Bio Pellets yesterday. Hopefully in a couple weeks it'll all be gone.

Chemiclean worked for me. That little jar will last years.

I haven't had much luck with C.S.

cwatkins, Be careful I am at the 3 week mark with Bio pellets and my PO4 is starting to climb up. Started with .05 3 weeks ago now I am at .11 (Hanna). I am running a small amount of GFO to help bring it back down.

+1 I had the same problem, ended up running GFO concurrently with the pellets because they weren't keeping the phosphates low enough. I ended up giving up on the pellets altogether.

Back to the thread topic, I ended up using chemi-clean as well, worked like a charm. Wasn't overly enthusiastic about the skimmer overflowing for days on end though but it got the job done.

Chemi-Clean works great. After using it and eradicating the Cyano I find if I use very small doses of it once in a while it keeps it away without the hassle of oveflowing skimmers and large water changes via the full dose.

Thanks for the heads up. I was planning on changing out my carbon this week and when I do I plan to do a layer of carbon then put in a separator, then put another layer of GFO on top.

Do you like the Hanna checker? I'm using an API kit and it's a P.I.T.A.

may need to use the zeozyme

do you mean last for years, you are still using it even without the presence of the cyano and using it as a preventive measures?:question:

thanks,:biggrin:

I've had problems with cyano every time I've tried biopellets and I've tried three different formulations at several different times and with and without GFO and still had the same problems. I have also had to concede that biopellets just aren't for me!
