120RK,
What a great build and your the first one that I've seen that has a Waterbox tank.
It looks like it's high quality setup and if it's 40% cheaper than a reefer, then it's a no-brainer.
I understand that your going with super nice that includes affordability which really means a lot.
Really looks awesome and if you don't mind I'd like to take the ride and read your comments regarding all the components.
If your thinking about going BB, I've been there for about 2.5 years and absolutely love it. I do miss things like Diamond gobies but the trade offs have been well worth staying bare bottom. I use a gyre (on full flow) to lift up and get the detritus into the filter socks. Then I use the Python No Spill hoses end (take off big end tube) to suck out the remaining detritus during my weekly water change.
Thanks, Freddie
