CTUV-H5P

I was excited to use this because I had a lot of green algae bloom in my 50 gal tank. I was happy to find out my UV light works as other reviews mention that sometimes is was defective. The filter has a small indicator so you can tell if the light is on. There are two power cords, one for the filter and one for the light that has a switch on it. The sponge filter at the bottom does a great job at picking up small debris and keeping small fish safe. It has a very powerful water flow and circulates a lot of water in my tank. The filter has many different sections, making it easier to clean. So far I’ve had no problems with the filter itself or the light and it’s been 2+ months. It includes an air hose which seems flimsy but works and you don’t have to hook it up to an air pump, it pulls in the air as long as it’s above the water.Downsides:Not long after I set this up, I noticed lots of white hair algae was growing on the wall of the tank where the filter outlet was pushing water. And the water flow was significantly reduced. I cleaned it and found more algae inside, not any green algae though. After a few weeks of cleaning and algae treatment, there has been less algae bloom and the filter has needed less frequent cleanings.Overall:This is pretty tall, fits in my taller 50 gallon tank. Great price, and looks like it will last. Would recommend using this if you have serious green algae bloom, and especially if you pair it with a chemical algae treatment.The filter has a indicator so you know if the light is on and the cord for the light has a switch to turn it on or off. Easy to install and use. Very quiet as it’s a submersible pump.

The product works great. My aquarium has never looked so good.

This thing works like a charm! The first photo was when I first put it in the tank. The photos are 2 weeks apart. I did see a significant change within a couple days, but now it’s CLEAR! The size was a little bigger than anticipated but fits well in my 55 gallon. The outflow of water is adjustable as well. I have it set pretty low because I have some small fish and shrimp in there. So it might have cleared things up a bit faster had I had it wide open. It also has 2 plug ins. One just for the UV light (which also has an on/off switch) and one for the filter. I strongly recommend this uv light if you’re struggling with unclear water!

Waste of money! I'm on day 5 of use and see no change in my aquarium. Does not do as advertised. It blows water out hard enough to move gravel and sand constantly. My fish hate it and it does not clean. Wish I could get my money back.

Ordered this product not knowing much about UV clearifiers or sterilization. Most of my issues I've been able to fix with simple maintenance and water changes. I do water changes every 2weeks, typically 25-30%. This is a Central and South American Cichlid tank. I've been battling the green water issue for almost a month and no matter what I did or how patient I was with letting it run its course it only would get worse. After about a weeks worth of research into is it really worth it I will 100% say it's worth every penny. If you enjoy your tanks and relaxing watching your fish move about, definitely get it you won't be disappointed.The only problem I did have was the hose they sent for the air. They package this cheap hose in a tiny zip lock all folded up so when you unfold it you'll have kinks n creases all through it.I attached a few pictures so if you're on the fence about it like I was, maybe seeing will help you decide further. Good luck 👍

I have a 100 gallon outdoor pond that had an algae problem. This unit cleared the water in about a week. Met my expectations and more.

The uv light with filter are working fine, the unit size makes me happy , the body is very skinny save my tank size, green water are remove very quickly in my case it only take about 1 and half day to rip the green, easy install, easy to take care and clean the pre filter sponge, noise not loud but it dose making sounds, only one I don’t like was there are no uv light timing control , this very no convenient, I have to use my own timer switch

Wow wow wow! Our tank suffered a horrible algae bloom with green algae and you couldn’t see anything past an inch from the inside of the glass. We have a 55gal fish tank and it cleaned it up in 24 hours! It did exactly what its job was to do. I’m impressed I thought it would take 3-7 days.The only down falls I would say are that it’s kind of noisy. Also it is a very strong flow! Definitely made for a big tank but it’s easily adjustable and didn’t harm my fish. The filter is obviously working because there’s a lot of debris on it after 24 hours. It has gotten rid of the smell also! I don’t necessarily prefer the 2 cords because I don’t need it except for the Uv light, so running just the filter isn’t necessary for me. I’m seriously so impressed with the product. Worth every penny.
