Dosage; +/-5%

Cont.: 5-Chloro-2-Methyl-3(2H)-Isothiazolinone-2-Methyl-3(2H)-Isothiazolinone

Would it be possible to use an UV dye with this product?
Go to a pet store that sells fish supplies and get some algae control. I use a product made by "Jungle" called "No More Algae" and have not had a single problem using a drop or two per loop with a drop top off about every 6 months.
