Aquarium Filter for 40-150 Gallon Tank, U-V Fish Tank Green Clean Machine Submersible Powerful Pump Canister Filter 400GPH for Pond Turtle Tank Saltwater Freshwater Crystal Clear Green Killing

I don’t usually write product reviews but I had to for this filter because I am so blown away by what it did for my tank. I was at a loss and trying all the chemicals, filters, and natural remedies that I could find to fix the algae overgrowth and smell in my tank. Frequent water changes, biomedia, a plecco, the works. I was about to give up and start a whole new tank but I decided to try this filter and it saved my tank in 48 hours. The water went from completely murky and green to crystal clear. The before and after pics that it shows are no joke. Here are mine. Literally taken 48 hours apart. I took my secondary sponge filter out & now only have this one. Recommend 100/10. It’s very strong though so I don’t recommend if you have fragile fish that need calm waters. I decided that mine will just need to learn to deal with the rapids because it works so well :) 45 gallon tank with 3 XL goldfish & a plecco but upgrading to a 60 gallon tank in about a month. Confident this filter will work there as well.

This isn't what you want for the price. Everything about it is cheap, cheap, cheap, and I doubt if it would pass CSA electrical compliance. The suction cup mount slides off way too easily, filter body below the motor falls off easily if not careful. The UV bulb has hairline cracks in it, and the wiring connections seem rather sketchy in my opinion. UV bulb is cheaply mounted in the unit. Unit has two power cords that are so short, they are useless and require extension cords if your outlet isnt right at the tank level. The cover on the powerhead always falls off ... it could have been so good and yet the cheaped out on everything

Very strong, so be careful where u place it in the tank. Other than that, it's great. Been using it for about 5 months. Easy to clean, comparatively speaking. Does a good job, and the UV does keep the bio residue down. I have a 40 gallon tank and I was finding that some were not oxygenating very good and I would end up with a gross tank. This works well.

Does what it’s supposed to do with ease! I had a significant bacterial bloom in my 20g nano reef tank that was getting out of hand. I knew I needed a UV on this system but was on the fence on which one to get. I took a gamble on this, even though I knew it wouldn’t fit in my AIO chambers. HOLY COW! Less than 72 hours after dropping it in the tank and plugging it in, water is Clear! This is not a high quality piece of gear, but it works for its intended purpose and is an extreme bargain over higher end UV systems. If you don’t intend to run UV all the time and need to remedy a current problem, I have no hesitation in recommending this. I have taken mine out for now as I hate having gear in the display area, but I’ll run it from time to time as/if needed

Very powerful. Mounts easily good build quality. I did cut the foam filter and add in some ceramic media to support a good ecosystem. The uv algae killer is no joke. I put this in a dirty green tank just to see if It could clean it. It stopped the growth cold and cleared the water in less than 24 hours (it was very very murky) I now understand why the uv light is separately controlled from the filter as it would kill too much algae if left on. I like to leave a little for the snails to munch I have it in a little tank and it is a little loud but thats due to the depth.
