vortech or tunze

[MarkoD]

i have an MP40 in my tank and its not noisy at all.

i cant even hear it over the noise of my return pump and skimmer (which are pretty quiet in an enclosed stand)

the vortech pumps are not focused flow. the stream that comes out of them is really wide. Plus they create undertow.

in my tank i run 4 controllable koralia 4s and 1 MP40. so i have no idea what the tunze offers
