Does the SunSun 304B have a way to turn on and off the UV Sterilizer? I don't see an on/off switch for it.
Thank you.

There is a on/off switch for the UV sterilizer.
Would this be suitable for a 125 gallon aquatic turtle set up?

This is very effective after adding the carbon especially which is sold separately. It has a nice shut off valve for cleaning filters so really you only need to
This is very effective after adding the carbon especially which is sold separately. It has a nice shut off valve for cleaning filters so really you only need to prime it the first time but i actually ended up pouring water down the tubs and that went much faster than priming. I’m very happy with it!

Works great and cleans the tank up beautifully
With that being said it was alil tricky getting it primed but once going it’s great and I will be ordering another to double the filtration on my new 180g

It hums along well and moves a lot of water!
Tubes were a bit hard to get secured but with the amount of water this moves; having them secure seems important and they look secure. Otherwise easy to set up

good filtration
only came with 4 trays of filter floss, no charcoal, ceramic tubes or bioballs as prior ones but also less expensive

Extremely Dissatisfied
I am super disappointed, was so looking forward to getting this filter and getting it running but while I was checking the items the UV light casing was cracked
I am super disappointed, was so looking forward to getting this filter and getting it running but while I was checking the items the UV light casing was cracked :( I was fully aware of a lot of other problems this filter had and was prepared to deal with them but wasn’t prepared for the cracked case. This is an extreme fire/electrical hazard. Hoping to return it and get my money back.

got 2 canister filters
I picked up two of these filters second hand but new in box. I use them 1 of them in a 30 gallon mud turtle tank. The other in a 40 gallon tank with two African
I picked up two of these filters second hand but new in box. I use them 1 of them in a 30 gallon mud turtle tank. The other in a 40 gallon tank with two African Side neck turtles. One the pump failed after a few months. I hooked up a regular pump inside the tank to continue to use it. The other has worked just fine. The filter media is poor and starts to fall apart with cleaning. Trying to find a media that works better is ongoing. No leaks it is quiet most of the time if it starts making noise a few pumps on the filter canister solves the problem. It is been a little over a year and the filter pump fail on one is my only problem no leaks on either. Water
quality is good.
