Blue Green Algae Killer


The BEST and ONLY EFFECTIVE BGA remedy. My tank had become an eyesore after the dreaded BGA took hold and smothered my thriving 150 gallon plant tank. Within days of treatment the BGA died back. My tank was clear of BGA for months. I treat a couple of times a year just to be sure it doesn’t return. GREAT product. I didn’t notice any issues with my biological filtration being negatively affected.
