Only reason I sold mine was because it ended up breaking the surface more than I wanted and ended up spraying my mesh cover with water. They also sucked in air at the level I had them.

My returns only have 2 pieces of loc line so to break syphon i needed to have them parallel with water line otherwise to much water would syphon into sump.

I also noticed that the amount of flow i had coming from my gyres ended up washing away the random flow patterns.

Return pump is pushing 350gph l, gyres are at 90%.

I’ve had the VCA dual nozzles on my Reefer XL 425 since day 1, so I don’t really have anything to compare them to. But I’m really happy with them and the corals are thriving so I have no complaints. I just cleaned them yesterday after 16 months of continuous use:

I'm putting them on my closed loop system so low in the water column, I'm running two of them behind 5300gph pump I was going for the 3/4 inch

I run a pair on my closed loop (which mitigates any disadvantages) and have been very happy with how well they work. They do require a pump that can handle a bit of back pressure.
