Please make sure you bring your copper PPM from 1.0ppm to 2.0ppm over a few days and if not TTMing them you NEED to keep them in 2.0ppm FOR 30 FULL DAYS!!! not 1.9ppm 2.0ppm!!!!!!! this is a must if you want to rid them of velvet/ick. So heres the issues with LFS DT... they usually only keep fish at 1.0ppm and strains of ick are immune to it, they keep these level low because of all the other sensitive fish in the system, thus only hiding the signs not actually getting rid of the diseases. what are the odds you have a small GLASS tank or container laying around?
