Congratz on your tank Adee, agree - this will look awesome when finnished, keeping an eye on the build 
So here are my questions where I'm looking for some advice:
Material for the roof (clear part), ordinary glass fine or should I go for acrylic, polycarbonate, clear fiberglass??
The openess in front, would it create a major problem in winter?
I could easily make a styrene insulator/cover and place over each night so to preserve warmth.
The area on the right will house some of the mechanics and also use as propogation area, all plumbed into the main DT. Any issues there?
The wife wants to put those folding/sliding doors to close of the front area, but eish the cost , should I rather do that?
Weyhey! Cool, AdeeLooking forward to the build.
Glass is best for light and durability, but it's a poor thermal insulator. It also requires a strong frame and is expensive to install. With regards acrylic and poly, I prefer acrylic. It lets through more blue/UV light and doesn't yellow as quickly as poly does. Fiberglass is a pretty good option, but it diffuses the light (some poly will too). One option to consider here would be twinwall poly. Cheap and easy to install and a good insulator. Redox used twinwall in his greenhouse: not the most cost effective greenhouse you ever heard of - Reef Central Online Community
Check out Hillaldam for sliding door components. They have some nice systems. Maybe you can figure out a way of getting the cost down?

I suppose Maizeys would stock the acrlic?...do you think would have that twinwall polly as well?
what thickness clear acrylic would be best?
You would want as much light to come thru tight?
Cool, I agree with you there Rob.Yes, you want as much light as possible, but the truth is you'll probably wind up with too much light anyway and you'll probably have to shade. I wouldn't worry about 85% versus 95% light transmission. The spectrum of transmission is more important, IMO.

Yep, Riaan...ive changed the plans again...made the green house section part of the main area. Will post plan updates.Your little greenhouse to the right. Rather have a door directly between that house and the rest of the stoep. After the 57 time on one weekend you have to walk around, you will wish there was a door.
Awesome boet simply awesome !!!!!!!!!
WOW! Adee! This is AWESOME man! What total water volume will you be looking at?
I am definitely following this thread closely! Please update often!
