wood, seems like all is going well for you i'm glad to see someone sstart from scratchand pretty much do the whole thing DIY, i'm currently waiting for tax $ to start mine, been buying things for the last year and a half to get ready for this tank, and still find myself needing to buy a few more things, but this hobby requires patience, and i don't think i can wait much longer to get started, but its been a much anticipated event for a long time now, i will be posting pics in a thread once i get everything together, right now i have a sump i made out of acrylic, not pretty, but it doesn't leak!!! andam about to start building my cabinet. well sorry to go off babbling, keep up the good work!
