Installed per directions. Several issues. 1) The knobs to control the flow rate were untested and have to be pushed back into place. 2) The internal outlet that is supposed to pour water over the prefilter doesnt have any output. 3) The biomedia isn't sufficient to fill it's basket. 4) The carbon packet doesnt fit the basket. *5) Most importantly, the uv doesnt work. The indicator light came on for 2 seconds and disappeared. I took it apart to see of it wasn't seated properly and discovered it was burned out. I bought a replacement bulb and reinstalled. Nothing.

Great filter!

Haven’t had it very long, but so far I love it. It’s quiet and my tank has stayed free from algae so far! Since I am new to this filter, I do have a question, though,

Haven’t had it very long, but so far I love it. It’s quiet and my tank has stayed free from algae so far! Since I am new to this filter, I do have a question, though, Chewy. Does the. Arvin bag need to be replaced monthly or ever? Thanks in advance.

Didn't work, right out of the box

We put it together and plugged it in. Not working, no motor sound. It was 60 days from our purchase and we can't get refund.

Nice design I like the telescoping water inlet, protein skimmer, U V lite ,no idea if it works ,easy filter cleaning . It could use a filter bypass feature to keep water circulation during feeding . Thought it a great idea for a filter and would recommend . Haven’t seen it around,do they still make it?

Outstanding Chinese product

I was skeptical at first. I am a American Fish/Aquarium Hobbyist. For the money and simplicity of use, this is a great secondary or even third back up HOB. WORKS

I was skeptical at first. I am a American Fish/Aquarium Hobbyist. For the money and simplicity of use, this is a great secondary or even third back up HOB. WORKS WELL ! Ditch the carbon and use purigen or other type of media.

I've had many of this type of filter over the years. This one is much like other brands in design. It is easy to set up, It is exceptionally quiet, and I like the adjustable flow feature. The UV is a bonus, though I am not sure the amount to exposure time is adequate. I have had several SunSun products (canister filters, etc) they have proven to be good quality for a reasonable price.
