I just used it on my 90 gallon tank. Instead of an airstone, I took the collection cup off the skimmer and am letting that provide all the air bubbles the tank needs. So far, I still have some cyano, so I am thinking of redosing two days before my next water change, so I can try to knock it all out since it seems to be stubborn as all heck, and also, so far, corals and fish seems to be doing just fine. I used 10 level scoops, for 100 gallons and have seen no adverse effects. I'll keep ya posted after the water change tomorrow.
