That looks like a lot of fun and I'm sure all the ADA stuff is top quality and now you have the authority to comment on the products because you've used them. I would love to do the same thing, lately some of the contest tanks have inspired me to try and get more out of my next build and this thread is definitely helping.
It'll be a while before I can definitely comment on the quality of the stuff. My espei rasboras took right to the AP-1 Gold, though. Time will tell. I'm glad you find this thread inspirational!
Placement of the main stone, not quite 100% on it. I think it may be alright though. Thoughts? I'm not worried about the substrate being even right now, I'll get to that in a bit. I've still got plenty of AS to sculpt with.
