the little white ones you gat when you slack on gravel vacking. protizoas i think their called. anyways with a 9wt sterilizer and a low flow rate can they be killed? ive heard salt and heat will do away with them. also the bait trick and getting some corries but im just wondering if the uv will kill them. im def gonna keep up the gravel vacuming and im sure this will help so dont tell me to go do a water change. thanks guys
