I currently have a couple Phiniac tanks and I love them. The only beef that I have with them is the caps are not cut to fit flanged cartos. What pyrex glass tanks come with caps that are cut for flanged cartos?
Easy answer. None.
Are you serious??? That blows! You'd think they'd get on that.
What's the big deal about needing flanges on the carto's. Especially with a Phiniac; it has a tight fit on the carto regardless if it has a flange or not. The flange only keeps the tank from sliding toward the connector end, not off the carto, anyway.
It's just common sense not grab your PV by the tank. Pick it up by the PV's body. Do this and you won't have any accidents.
