Chemi-clean feedback

[asylumdown]

I've used it in my tank twice now. The first time was probably in the spring or summer and I don't think I used enough of it or for long enough and the cyano came back within a week, but other than that and a skimmer that went crazy for days, there were no other effects.

This most recent time, according to date stamps on posts here, was just about exactly a month ago. This time after the 20% water change at the 48 hour mark, I did a second dose to try and make sure I'd killed it all. Strangely, even though I know it's not supposed to work on them, the dusting of dinos that have waxed and waned on my sand bed for the better part of a year (and I've confirmed their identity under a microscope) utterly vanished. I only let the second treatment go for 24 hours because my elegance coral and one of my frogspawns were starting to look a little worse for wear, so I did the 20% water change, dropped a bag of carbon in my filter sock, and skimmed wet until the skimmer went back to normal (about 3 days). When I did that last water change I tested my phosphate levels and they had jumped from 0.00 on a hanna checker to 0.05.

After that I started an aggressive dosing campaign of MB7 (the tank runs biopellets) and changed the GFO every few days for a couple of weeks.

January 15th and there isn't a trace of the cyano. All corals are doing just fine, though I think I might have driven the nutrients too low.

I know some people say they've nuked their tanks with this stuff, but I've never seen so much as a reaction from anything, other than the widespread death of cyano bacteria.

From what I can find on the web, I would attribute this to either over-dosing due to a lack of true system volume knowledge, or a lack of oxygenation

No damage at all after second outbreak and treatment but I confess I did not use it full strength. I still have 2 small patches in the display and a 5cm area on the front panel of the refugium.

So you dosed it 2 different times ?
When was that ?

Used it once a while back, full dose, left it in for a week. No issues. Skimmer wasn't happy for while tho

As in, nothing has come back, no Dinos or other outbreaks etc ?

Nope. I wouldn't hesitate to use it again, if I ever needed to.

Waste of money , I used it , came back with a army a month later .

So I bought a better skimmer , up my flow , and purged my sand and rocks every water change . Never comes back .

Sometimes it will show on the top of my over flow , but it never spreads and just tells me I need to do a little bigger of a water change this time and it goes away .


Find the problem . Chemiclean should only be used to save frags and corals from being choked to death .

Also have patience , it eventually will give up if you don't first .

Used it roughly 9 months ago; worked great for what it needed to do. No issues aside from the skimmer taking nearly a week to stabilize. While using the chemiclean, I just took the collection cup off the skimmer and it became a super oxygenator for the tank.

Used it once and lost my clam and some inverts I had the skimmer running and overflowing into the sump looking back I would have to agree with gregzz I may have overdosed only by a little though but it sure got rid of all the cyano fo sho!!!
