Chemi-Clean, 6 grams

Chemi clean is a reliable tool to erase cyanos out of the tank. Yes, corals do ok but yes they still feel it. I say that based on the trident reading that showed lower alk consumption, but like 15% lower. I'm happy with that. Consumption came back up fast and no corals died. I've used this product many times with success. Can't say the same about the competitors.

Worked as promised and now I use if as a preventative measure often!

helps remove the junk to a good degreeside note: this is an old packaging pic and should be removed

I use when I see the beginning of a cyno outbreak.. usually 1 treatment will knock out the problem.. if you continued cyno problems then maybe there is a different issue that needs to be addressed.. this product works .

Works great! Removed a tank full of cyano in one dose. However did kill two of my orange bubble tip anenomies.

Works as advertised. No problems encountered.

It works good. Got quick

I tried this two times (with a water change in between.) I double-checked the directions, thus making sure it wasn't my error. Nope...just ineffective for my tank.
