wow, its been a while since i've seen my own thread, it seems like i need to post an update. I've been at school, and my AP 24 is a display tank at my LFS. I'll be able to see it inabout 2 weeks, I plan on postin some new pics
I really like the idea of the rock and sand rubble you used in your tank, looks really nice
There is a guy who did a 5.5 nano and used the spray foam as well, he textured his with a wet putty knife, and it looks awsome, better than a regular foam job
I just recieved my AP 12 70w HQI YESTERDAY!! so excited, and i'm pickin up some spray foam today, planning on texturing it, with a sponge, and will be building a thread on that...
I'm pretty sure it wasn't the foam, its non toxic to fish and plants. One of the TOTM's has it on his 375, that looks great, and his tank is thriving, maybe you had a temp spike??
