very unique build, lookin forward to seein it progress
I do have a couple questions. how do you intend on maintaining water level with your inflow there? just seems like a couple days evap and you could be suckin air, but maybe you've added something I'm not seein or maybe I'm just seein it wrong. Also, what's your main water source? I've been tryin to figure out ways to lower my pH since I live in a hard water area..
You mentioned orchids earlier, sounds sweet! still plannin on that?
Good luck with the rest, I'll be watchin
