Hi all. I'm currently in the process of building a 230G saltwater setup. I want to pretend that I have infinite monetary resources to buy two UV sterilizers, one for each return pump, one for algae and bacteria and the other for protozoa. I believe I want the Pentairs. The Pentair 25W is suggested for 130G aquariums or less. If I got two of the 25W, would that suffice, or should I still get the bigger size. The issue isn't money so much as it is the size of the sterilizer. The 25W is 29"; the 40W, which is for 260G or less, is 43.75". I would have to mount them horizontally instead of vertically, which I was hoping to avoid, and they just don't make it easy to plumb based on where my sump and returns will be. Any thoughts?
