Chemi clean

[TLO45]

I recently doser chemi clean to rid a Cyano outbreak. Used the recommended dose and did the job. Now I’m having issues with getting it out of the water column. System holds ~400 gallons and have done 5 50 gallon water changes in the last week. Have been running carbon as well. Skimmer has settled some but not all the way. Anyone have had issues with this and other than keep doing water changes anything that will strip this from the water quickly?

Elaborate on getting it out of the water. What is the it you speak off: Cynobacteria or the ChemiClean

I have used it recently after one 10% water change in a 125G system it took about 5days to get back to normal with all cyno gone

Just skim wet, and keep dumping the skimmate. Water changes will be pretty inefficient.

I used it about a cpl weeks ago now. Did 30% change as directed and had to do another 30% change a few days after that. I experienced a huge nitrate increase most likely from cyano dieing and releasing back into system. Cpl weeks later nitrates are still a little high and skimmer is still pulling purple, red gunk from water column. Took my skimmers few days to settle down but I super aerated my system when I treated it with chemiclean. The more air I was able to pump into water the fastest cyano melted away and still none present in system. Besides whatever is being pulled in skimmer cups.

Directions Step #7 & #8 recommend 20% water change and renew granulated activated carbon.

Seems like you exceeded that recommendation. What’s the problem?

Were you running an airstone while using the chemi-clean? My water has always been crystal clear after running a chemi-clean treatment and doing the aforementioned 20% water change. What is leading you to believe it is still in your water column?

 

[TLO45]

Because the skimmer is still overflowing. Did the carbon, did over 50% total volume water change and aeration of tank. Continues to overflow skimmer.

What i had to do was actually crimp my skimmer air lines for few days until it settled down enough to get l back to normal. Crimping lines it still took few days to settle down and run normal.
While I did this I still ran an air stone in sump.

Looking back I probably would have just hooked a tube to my skimmer cup drain and let it drain to bucket until it settled down. And mixed new water to replace.

I think what your going through is totally normal especially because you used it correctly and super aerated tank.

In the past when I've used Chemiclean, I usually took the skimmer cup off and let it overflow back into sump. It usually took 4-5 days before it would settle down.
I just tried a different approach and that was to add Chemiclean to my ATO so it didn't give 1 large "hit" to the tank and in a matter of a week cyano was dissolving and skimmer didn't go into overflow mode. It'll probably take 2 treatments this way and take a little longer to eradicate cyano.
