Midnight

this reminds me i really need to clean my skimmer....sigh..maybe monday lol

just curious what skimmer that? it looks like a euro reef but it could also pass for a vertex or i could be totally off

I just finished up with a chemi clean dosing myself. I found that after 48 hours, my RBTA and corals were getting noticeably pissed. The water started getting cloudy and I started getting nervous. As much as I wanted to, I couldn't wait for all of the cyano to be visibly gone before I turned on the skimmer to bring relief to the inverts. I read on here someone commenting about how chemi clean is a super safe treatment and that they've even witnessed spawning during treatment. I wonder if that's the kind of spawning stimulated by poor water quality... I'll be interested to hear about your experience.

Baker, the skimmer is a Reef Dynamics (formally Euro Reef) Ins 180. It is a hoss and generally over skims my set-up. I believe I will be upgrading soon to a larger system and will not need to replace the skimmer. The other thing I really like is the twisting collar that allows for zero clearance during skimmer cup removal.

Blennyman, on the bottle it says you are allowed to do a water change and repeat the process. Not sure if that helps. The cloudiness could be from a spawning event.

I forgot to mention that all of the Cyano disappeared over the course of the next couple of days. I guess my point was supposed to be that in my experience (sample size of 1) the cyano doesn't have to be visibly gone or "dead" before you turn your skimmer back on and start your water change. If things look bad, I wouldn't wait 72 hours before skimming. My other poorly made point is that I don't think spawning is an indication of good water quality and that my tank got visibly stressed - though I didn't have any losses. The last thing is that I'm not good at making points late at night.

any time I ever ran Chemiclean I would dose have the recommended amount and get great results with no visible changes in water quality followed after 72 hours with a large water change, but before doing that I would always try and manually remove all of the cyano I could so when it all melts away it would reduce the amount of bad stuff it released into the water column. When I still had a RBTA (died during tank relocation) it never showed any signs of distress during the treatment and the same goes for all of my inhabitants including CUC and shrimp

Ah yes, that's certainly one thing I didn't do - siphon out the cyano ahead of time. I wouldn't say my cyano had reached plague proportions by any means, but it may be the difference maker in our experiences.
