Awesome build man! Been following and felt nervous too but glad it all worked out! Doing similar build but mine is a 300 gallon (96"Lx24"Wx30"H) with 1/2" glass and GE silicone. The stand and "box" is put together. Now the part that makes me nervous.
Still deciding on the waterproofer, was gonna go with Liquid Rubber but didn't like how it turns brown, then thought about West System or MAS with black pigmant. Being in Canada and hazmat/border shipping costs, Sweetwater is out
Like you, MAX ACR (with black pigment) sounds like the product I'm probably gonna go with. Did you say for your build you only used 1-1.5 gallon kit and got 6 coats? If 1 kit ($85-Ebay) was enough for yours, it should be enough for mine right?
Thanks for any help you can offer and can't wait to hear updates and see yours stocked!

The most nerv wracking part for me was putting down the fiberglass cloth and the epoxy, but the Max Acr was a dream to work with, no different than painting a wall. Just make sure you buy a solvent roller to put it on, I figured that out on the 4th coat 
I would apply the first coat with a good paint brush and thin it out with Acetone or denatured alcohol to get a good "bite". After that it's as simple as rolling it on. I waited not quite 24 hours between coats (sometimes as little as 8 hours depending on work schedule) and did a very light sanding between coats with 220 sandpaper. 1 1.5 gallon was enough for the 7 coats + putting down the fiberglass, stuff really went far!! Good luck 
Now time to warm up and let the water clear and I'll take some pics, probably won't be til tomorrow I'm guessing, it's pretty cloudy after leveling the sand.
