Pentair Aquatics Rainbow Lifegard 40 Watt UV Sterilizer QL-40

 
UVs are an effective method of disease and algae control, without using harsh chemicals. It has a quartz sleeve and bulb, UL and CSA listed. Can be used with an existing Rainbow system or added to most canister filters....

Effective, solid design featured

General I have the 80W design of this UV and the only difference is that there are two ballasts and two contact chambers instead of only one. In-all, this UV was very simple to set up and get running on my ~400g system quickly. The instructions were easy to understand but not really needed. The overall unit is built well and quite sturdy. The overall height of the unit is about 36" (forgot what the Pentair says the true height is) and maintains a relatively small footprint (12" square or so--the 80W is double obviously since there are two exact chambers conjoined).

Water clarity has been excellent since adding this unit. My only problem is one of the ballasts quit working about two months after purchase. After contacting the manufacturer for a replacement, the old ballast was returned before a new one was sent. The whole process took about two weeks. The new ballast sent is a "new" design which does not have the rubber boot on the top as the previous reviewer mentioned. Pentair went the UA approval and had to change the cap design (where the wiring meets the connection to the actual UV bulb) and the wire is now a commercial insulated singular wire (versus two--red/black--thin 18g(?) wires). It now looks more professional however, the second ballast did not work on arrival and I am in the process of having this replaced again. I am also going to return both ballasts this time so that I do not have one "old" ballast and one "new" given the aesthetic looks of the new versus the old setups.

In all, with only one chamber (ballast) working and pushing ~700gph of water through it, it has kept my water column very clear. I am quite happy with the unit. I will be even more so when the unit works as it was initially advertised and purchased.


Liked about it Easy to plumb this unit; solid design; intiutive and easy bulb replacement.


Didn't like "Older" version has a somewhat unattractive two-wire design and capable but piece-meal top-cap setup.

Pentair Aquatics Rainbow Lifegard 40 Watt UV

General All and all this was a great purchase that didn't break the bank. I'm running it on a 300 gallon system, with about 200gph through the unit. I'm running it for the sole purpose of water clarity which it continues to do well. I've been running it for just about 2 years now.


Liked about it Very simple to install if you plan ahead. It comes with just about everything including the adapter is you want to run one inch PVC in and out. The ability to change the bulb without shutting the pump off is a nice plus.


Didn't like The ballast is just a basic workhorse style ballast and the wiring is less than attractive. The rubber cap for the top of the bulb doesn't fit snugly on the top of the filter, but it is only a cosmetic issue.

Liked about it You can change out your bulb w/o having to stop water flow in this unit.


Didn't like Itis a very tall UV so u cant hide it under your canopy
