to answer your questions, yes I did use filler and sanded it so there were no seams, the bottom front section is actualy made up of 5 different pieces plus the 2 doors.
I used a particle board, I want to say MDF, 1/2" thick, I just looked for a board that was pretty light, but sturdy and the edges could be sanded down smooth.
Finally finshed, for now anyways, I know I definitly want more rocks in the future!
Now onto my next tank I guess, just waiting for the driftwood to stay sunken, hopefully it wont take too much longer
Any suggestions?
ps. I dont know whats up with my camera, think the lens needs cleaning, and I guess I should have cleaned the tank glass, but I am just too **** excited about it, not to show pictures right away!
pss. thanks for al the positive feedback so far...
