Review on 🐠 Adjustable Reversible Purifiers for Aquariums – Plastic by Brian Page

Don't buy this. The extra angle at which it screws into the ball valve is an extra spot for the leak to occur. When I did the fit just to see - so one day I sealed it with teflon tape. Guess what. The ball valve didn't even work. So if you don't have a timer, this thing will flood your space. I thought I was getting value. Instead, you suffer water damage. Too bad I didn't install it sooner because now I can't even get it back. I have 7 days past my return date.
