vortech or tunze

[Funky_Fish14]

I have 2 MP10wES... 1 is set to reef crest(at 100%) and 1 is in lagoon mode(at 80%)... Opposite ends of the tank. There are no dead spots below or around the powerheads (water flows fully all around the front 3/4 of the tank).

The newer one is fairly silent... yes I can hear it but its not bad. The older one (6 months?) is about 4 times as loud at the same settings as the new one. I dont know why, and plan to speak to the retailer or ecotech about it. I understand ecotech customer service is very good though.

Cheers,

Chris
