Recently I thought my fishes were having white spots and WATERLIFE myxazin + salt + 32°celsius kills most of it.. I tested my water and nitrate/nitrite are all "0" I was wondering if fixing a uv light on my canister filter actually works as it's supposed to kill off unseen parasite? Or its a waste of $? Or more frequent water change eliminate the need for uv?
Hi I was just thinking, would an UV steriliser be more effective with a slower filter flow rate, as it means more contact time between the water and the UV radiation?
