As a long time Tunze user/owner, I swear by Tunze products. I have two 6205’s and 1 6105 in my main display that I absolutely abuse and have been doing so for nearly 7 years straight. I have have two 6095’s in my display refugium and a 6055 in my frag tank. I’ve owned a lot of pumps and power heads over the last 30 years but nothing has ever compared to the Tunze’s in terms of flow, quality and reliability. As such, they are and always will be among my favorite products. Anyhow, I joined the contributors group and have a build thread here detailing my system. I’ve been pretty bad about updating it with new pictures but nothing has changed. My system is in cruise control so to speak. The corals are growing out of the water and everything is thriving.. Here is a link to my build thread.
