Hi Tom,Rudy,
I'm glad to help if I can. I can say that bowing is not much of an issue with a Tenecor tank. They are very proud of their work and won't under-spec a tank. My only bowing is on the top plate and it is VERY slight. I wouldn't be concerned about it from most custom fabricators. The mass-produced tanks are a different story and every one of them I have owned eventually bowed to unacceptable levels. Tenecor tanks are all hand fabricated although they use high-end CNC machines for the cutting so kind of the best of both worlds, precision cuts and hand-crafted assembly.
I'm pretty sure that the 100 Lagoon still ships with a Sicce SDC 6.0 pump which can be dialed way down if desired. It is a top-notch DC pump. The current 100 Lagoon is not a coast to coast but it is still 8" wide and full height. Lots of room, even for a full-size skimmer. Also the tanks are now split-return so you can really put the flow where you want it plus the end panes are the full 30" width which looks awesome. It would probably work really well for a freshwater set up. I like the 16" Lagoon height as it is also easy to work in but I like a relatively-fine sand bottom and, because it is a mixed reef, high flow so additional height would be welcome in my case to reduce the sand disturbance. From your description, I think a Lagoon might be ideal for your setup. Be sure to start a build thread when you set it up so that we can see it.
Tom
Thanks again for the prompt response and your insights.
I'm not sure if this is good or bad: I decided to check into Tenecor website to take another look at their 120 Lagoon AIO and noticed that the website had disappeared. I was a bit surprised. Another member "BetteMidler" also commented the same thing where website was down.
