Awesome tank! Yet another I have to tell myself I don't need... I like that it's "Iwagumi inspired" as well. IMO, sometimes the straight-up Iwagumi style tanks can be kind of... "meh" lol. Nice rock/wood work too!
What's that spiky stem plant sort of back-right? I've been considering something like that for one of my tanks- it's super cool looking!
I just decided on an Aquatek set-up for CO2 also. Need to save some money right now, got a paintball tank for free, and they look pretty nice. Let us know how you like it down the road!
Excited to see how it all fills out!
