Currently right now I have a freshwater Koi pond with a UV sterilizer with an 80 W lightbulb in it that is taking care of the fish pond outside, after dealing with brown jelly disease in my tanks currently I am running a small standalone pump through 16w UV light in my sump, I’m going to be dealing with approximately 300 gallons of water in total system capacity in the next couple days. I want to know if there’s any pros or cons of running the return line of my frag tank which is going to be the larger main tank for my coral through a large 50 W plus UV sterilizer. I’m not looking to spend in arm and a leg on one considering my 80 W fish pond UV light was 150 bucks. I can buy a 55 W one for $109 right now but I’m curious half of them are stainless steel and the other half are plastic is there any recommendations from the reefing community that I can have and before people say buy a saltwater one, most of my tank is rigged up, I can’t afford to buy expensive equipment. The main question I’m going for here is Would stainless steel be a problem or should I go full plastic.
