Seeing what's some good suggestions for a UV sterilizer for a 220 gallon tank . Price and quality obviously the 2 sticking points. Thanks. Oh and one that sits inside the tank since I won't be running it in a sump type return line.
It really depends what you want the UV to do, since most UV's are clarifiers that are designed to kill algae but little else...
If you are after a UV sterilizer unit that can kill parasites and other nasty stuff you'll need to make sure its rated accordingly and that the flow isnt too strong that there isnt enough contact time between the UV and the water flowing through to kill off any free floating parasites etc...
