“Looks a bit strong if you think about it these fish don’t swim in that shallow ocean water and the flows aren’t this strong in their real environment”— @placemarker762 on YouTube
“I wouldn't buy it again if I knew I couldn't use it's full potential, but instead go for a wavemaker instead I think.”— Bananam00n on Reddit
“Looks like too much flow for such a tiny tank”— @malawimaya on YouTube
“I wanted to chime in and say that my XF330 is annoyingly loud to see if anyone else thinks the same thing. I'm running it at 60% random on a 40 breeder, and the hum is audible from across the room.”— cain720 on Reef2Reef
“They have a huge manufacturing defect problem on these rotors. I bought a brand new xf330 cloud edition from brs and it came with a horizontally cracked rotor.”— artman on Reef2Reef
“I bought the xf 330 cloud edition last November. So far I've had 3 failures all due to the same reason”— Mark-Stover on Reef2Reef
“After 13 months of owning the 330s I'd say don't waste your money.....They stink! I have a 4ft long tank. One pump (A) runs at 20% and the other (B) has to run at 80% in order for the flows to meet in the middle otherwise the 20% pump overpowers the other one”— Firemanreefkeeper on Reef2Reef
“have had the same issue but mine has like disintegrated, it's only like 6 - 8 months old.”— FishOkay on Reef2Reef
“i bought this pump back in 2020 and within a year and a half this happened”— odariel on Reef2Reef

Not complaints — practical notes from owners that didn't affect the score.
“I use 330s and the maxspect controller used 20% as a minimum in many cases and as low as 10% on modes like LTC. I similarly want my minimum speed down there on hydros but am cut off at 25%.”— Braysky on CoralVue HYDROS Forum
“My xf330 barely spins when hooked up to my wave engine, if I enable reverse function it runs normal speed when it thinks it is in reverse, somehow it seems to have forward and reverse mixed up”— goggs29 on CoralVue HYDROS Forum
