UV Sterilizer Sizing for Water Clarification

MSB123 · Oct 12, 2018

I stand behind Pentair. I have had 3 UV units from aquauv, all have broken or arrived broken. The 2 I have from Pentair have been running nonstop for about 3 years on one and another one I got used has been up for about 8 years, never had any problems from Pentair.

I run my 240 watt for 4 hours a day at 500 GPH

"level of clarity I didn't know was possible" is exactly what I am looking for. AquaUV sells a 57 watt model that is only 20" long..... $450 vs the $750 50W Pentair model.

OMG how did I miss that!! Lol. I went through all that effort plumbing 2 together when I could have just got a single 57 watt unit! Ugh.

But, I wonder if the longer dwell time of having 40 inches is what is really made the difference when adding the second unit.

Question - Did you run the first 25W unit 24-7?

Yes. 24/7 in all cases.

My recent experience with a bacterial bloom and getting UV.

How did they break exactly so I can be on the lookout. Mine arrived in perfect condition so far. Thanks
