I have a 3 month old, 240 gallon tank. 350 gallon system total. I have a cyano outbreak. Not too too bad, but I decided to dose it with chemiclean. I'm on the 3rd day, and the cyano hasn't diminished that much, if at all. One fly in the ointment is that I forgot to turn off my UV at first, UV was running for about 10 minutes after I added the chemiclean. Would that matter? I think I did everything else right - I disconnected carbon, and plumbed my skimmer overflow back into the sump.
The other thing I'm not clear on is the dosage. I added it by weight, not spoonful. The instructions said that to add 1 spoon per 10 gallons, and that it was .1 grams per spoonful. So I added 3.5 grams. But the bottle says that it contains 6 grams and treats 900 gallons. That math doesn't work. If it's .1 grams per 10 gallons, then the bottle would treat 600 gallons, not 900. What's up with that?
Anyway, should I give up and do a water change? Wait it out longer? Do a second dose?
Thanks!
