[When you dose Chemiclean:
Determine the water volume you have to dose. Discount the rock, sand and figure only what water you have, if possible. Remember, the outer dimensions of your tank do not represent the true volume it can hold. For example, my tank is 72 x 30 x 30, and is listed as a 280g. In actuality, it is 71 x 29 x 28 and holds 249.6g. (L x W x H / 231 = Total Gallons)
Mix the amount of the powder with a cup of RO water. Pour it in your tank in a high flow area. Take your time, there is no rush.
Turn off your skimmer for 48 hours.
Run an airstone to increase the oxygen level in your tank.
If you still have cyano, repeat the dosage again, waiting another 48 hours.
Change 20% of the water.
Turn on your skimmer and be ready to pour out the collection cup repeatedly that day.
Your pods and livestock should do fine. I just double dosed my tank as above, and everything moved on as normal, and the cyano bacteria died completely.]
