Is using Chemiclean to control Red Cyno safe

whiterushen · 10/22/2019, 04:52 PM

Is Chemiclean safe for the inhabitants? I was reading the directions and it seems it deprives oxygen in the tank. I have a 20g and did a treatment to control Red Cyno algae bloom. The largest fish looks like it stressed a bit from the treatment. I reinstalled the carbon and phosguard filter pad and did a 20% water change. Just looking for opinons from others experiences using this.

I have no problems but heard others have.
No idea why.

Cyano is bacteria. Not algae. Chemiclean definitely works but as u know you need to tirn off skimmer and increase aeration.

Do lookout for Redfield ratio to find out more..

Usually what i will do is to dose bacteria to compete and eliminate the annoying cyanobacteria.

Used it a few times without issue.

It's generally safe, but killing cyanobacteria can release toxins into the water column. In addition, the cyanobacteria generally will return if there's an underlying problem. Some large water changes (15-20%) and carbon can help reduce the odds of problems, and siphoning out as much of the mess as is easy to get before dosing can be useful, too.

I leave my skimmer on but remove the collection cup.

That's a good idea, too. Aeration can help with any oxygen consumption due to decay.

For my part i have better results with "blue vet cyano rx".
+1 for the removal of the skimmer cup, never had any loss of life due to this treatment.

So i just wanted to update you guys--- Even though my larger fairy wrasse got a little stressed out from the toxins released from killing the Red Cyno bacteria and lack of oxygen in the water, the results were great! The unexpected benefit came that I did not realize that the red Cyno was stressing out my SPS corals. Apparently the bacteria bloom seemed to be "choking" or suffocating the SPSs from getting the proper oxygenation from the water. Once the Red Cyno strom calmed down, the color came back in my SPS corals. 4 days later and there is literally no trace that my tank ever had Red Cyno and little to no clean up required (other than the intake sponges).

That sounds like good news. It'll be interesting to see how the tank shapes up. The cyanobacteria might have been emitting toxins that cause problems for the coral.
