Got a quick question please , I'm wanting to put a UV sterilizer on my 240 litre tank. I'm running two cannister filters. Which are 1800 and 1500 lph . Now I want to add a UV , so I'm thinking of putting something like a Fluval 107 as well ( tanking media out , possibly? ) , so it's got the 500lph flow rate that the Eheim UV 500 needs. Do you think this would be good idea ? . Or should i go down another route.
