Nereefpat....you state there is no reason to mess aroind with UVC germicidal sterilization. My question to you is...why not use it?
Even if it only kills 25% of the free flowing ICH eggs flowing around...its 25% more kill than just standing in front of your tank with your arms folded.
UVC has cleared my water to crystal clear. Hasnt negatively effects any corals, fish, inverts, lil copepod, the good lil bugs thst live in the LR.
I cant find a single reason not to use UVC as a preventative measure against a list of bad parasites in the water column.
"Booksmarters" say UVC is ok at best. they also say it weakens plastic. BONK! it may put a slight brown discoloration on the plastic but in the 3yrs ive been using UVC my plastic near it is as strong as Day 1. I kniw bc ive inspected the plastic pipes inside my overflow that has been expsed the UVC light for 3 yrs. No softening. No weakening.
"Streetsmart USERS" like me are seeing r.e.s.u.l.t.s.
