The aqua uv pees me off a bit when you realize outside of the funky bspp threads it's just about all off the shelf pvc. They are making their cash for sure, lol. I never paid full price for one and don't intend to.Bought it Nov 2021
It has directional connectors and the ballast counts down to bulb change and it has replaceable sleeves so the PVC doesn't degrade eventually and so on. My Aqua UV was just a tube, idk where they factor in their cost.
