i went off of garfs plywood tank plans after trying to eliminate the four joints in the front face with bondo cracked open everytime and several attempts to repair almost a gallon of bondo later and weak top strip that i didnt much care for i cut it all out with my skillsaw lost some length so i will have to get my glass cut i live nearby so no biggie the piece i replaced this with consisted of four 2by 4s and a 3 quarter inch subfloor piece i placed the pieces flat on the 3 and a half side not the inch and one half then i laid the plywood on top after gluing and screwed it all together seperately from the rest of the tank so i could cut the hole out i went 3 and a halh inches on my cuts the same dimmentions as a 2 by 4 and patched all screwholes i put extta effort into this piece because my glass is going to sit against the plywood nad the 2by fours sit outside the plywood flush to the rest of the tank so the glass will actually sit 2 inches inside the build i also built a stand that the tank sits inside low to the ground because my tv stand is built in on top but is incomplete rough framed the end result a very strong front face on the aquarium and i cut the hole out so theire was no joints i painte the face gloss black and and put an aquarium background across the the back of the inside that i glued in with silicone this is already waterproof quick easy and relatively inexpensive it cost me 20 for the picture and four dollars for the silicone im going to put an extra step in and either sheet it with something clear a piece of glass polyurythane or some epoxy havnt thought of very many things to seal it in with yet and am working on it and i am definately looking for more suggentions on this did i mention this took me less than 20 minutes
