SUN Original Spare Part Waterproof Tube for Sunsun JUP-23 UV Filter

used this in our pond. Helps reduce growth of unwanted algae. Easy to install, works for intern intended purpose.

Worked well but only for 7 weeks

Probably my fault, but I thought this four prong light was a much smaller form factor. When it arrived it was like an amazon (no pun intended) compared to the size I needed, so I needed to return it

I didn't realize that my old bulb had failed. The tank got nasty. I replaced the bulb and the tank has cleared up. Great product.

I waited to long to replace. It helped clear up my aquarium water.

Light works well with a great price and fast delivery.

Im still trying to find out how to get a full refund as all these bulbs did not work in the aerus air purifier they were purchased for very disappointing I need to ship them back and get a refund

Awesome
