Plenty of tanks, mine included have gotten by just fine without having one. IMO I don't understand the reason to have one.

Definitely worth keeping an eye on. Mine never had light bleeding through either. I didn't notice anything until I saw water pooling on the floor beneath it.......the body itself didn't fail though. Mine failed where the pentair connections met the main body.Thanks, checked mine (2 yo) last night and no sign of light bleeding through.
Asked my LFS who was not aware with the issue with that brand but was with other brands which have failed.
Looks like replacing the main body will need to become a scheduled task every few years.
Do you guys think the 15 watt aqua ultraviolet steralizer would be good for the 55 gallon tank? Is that too much or too little? From what I’ve heard it’s the only steralizer I haven’t heard anyone say any problems about.
I’ve been looking at UV Steralizers and I am mostly stuck between 3. I have a 55 gallon tank and I’m looking for a steralizer that doesn’t only help with algae, but also kills parasites, more specifically ich. I am not looking to spend anywhere over $200. I was wondering what the main differences are between the green killing machine, the corallife turbo twist steralizer, and an aqua ultraviolet one. Which would be the best for me and what’s the actual differences other then price.
I believe Pentair recommend 280,000 uWs/cm2 exposure for control of Cryptocaryon Irritans (Marine Ich).From talking to one of Europe’s largest importers of saltwater livestock who is also a manufacturer of uv units, in conjunction with my own research aiming for a high enough number of uWs/cm2 to actually kill marine ich isn’t really achievable…or at least not practical. It seems to be right around 340.000 uWs/cm2 which for example would mean that I could only run 750L/h through my 110w unit. Perhaps not a problem in itself but you also want to factor in that you want at least a 2,5-3x tank turnover every hour to make sure you hit a high volume of the total parasites.
Sterilization it probably where it’s at and that number is right around what pentair recommends: 180.000 uWs/cm2.
Knowing that and that you want to have around a 3x tank turnover an hour you can easily calculate if a unit is appropriate for your tank
Huh, strange. This is what I find on BRS on the pentair products:I believe Pentair recommend 280,000 uWs/cm2 exposure for control of Cryptocaryon Irritans (Marine Ich).
That's the level used in Aquaculture systems I'm familiar with. They also implement Ozone.
Huh, strange. This is what I find on BRS on the pentair products:
280k will definitely be a lot better and have more sterilizing properties (perhaps will even be enough to kill some?) but probably not feasible for a hobbyist. I believe the 180.000 uWs/cm2 is a recommendation based on what’s possible to implement in practice whilst still having a “therapeutic” effect.
180k is still not achieved by most people whilst also having the proposer tank turnover through the unit. For example my 110w unit is still undersized for my 1000L DT and 450L sump since I haven’t found a good way to mount two of those in a series.

I installed that exact one a month ago. Did my research on many models. Pentair had a bunch of quality challenges and seemed to be much bigger and more of a commercial option. I run mine 24x7 right from my return pump. Water is crystal clear. It doesn't help much with cyano at this point however I was more interested in water clarity. I can adjust my pump speed if I feel the need or am concerned about ich. IMHO. The benefits of sterilization of all the water are worth the 300.00 bucks.Do you guys think the 15 watt aqua ultraviolet steralizer would be good for the 55 gallon tank?

Uv isn't meant to "kill" ich. I believe it steralizes them once in the water column and thus will greatly reduce the chances of infestation.As far as specifically killing saltwater ich.
It doesn’t seem anyone has landed on the exact number for killing saltwater ich other then it is clearly it needs more then freshwater.
There hasn’t been a ton of research on it.
“Use of ultraviolet (UV) sterilization to kill theronts has been suggested, based on research involving Ichthyophthirius multifiliis (freshwater “ich”). The recommended UV dose for Ichthyophthirius theronts is 100,000 μWsec/ cm2 (Hoffman 1974). However, UV doses required for Cryptocaryon irritans are anecdotal or extrapolated, and range from 280,000 μWsec/cm2 (industry numbers) to 800,000 μWsec/cm2 (Colorni and Burgess 1997).”

So basically suggestions on which UV should be taken with a grain of since there is no agreement on what is needed to kill saltwater ich other then it is a dose larger then freshwater.
Doing the math to get a hopeful idea is probably best before purchase as it will at least tell if the UV you are buying is useless and lacks power and is more suitable for freshwater ich.
following! i’ve been thinking of getting one and also have the same question
yes, I meant sterilize. tyUv isn't meant to "kill" ich. I believe it steralizes them once in the water column and thus will greatly reduce the chances of infestation.
the right UV Sterilizer setup will 100% get rid of something trivial like ich. My tank is a breathing example of complete ich eradication even though I was completely skeptical at first before I caved in and set it up.Uv isn't meant to "kill" ich. I believe it steralizes them once in the water column and thus will greatly reduce the chances of infestation.
