now its got to move tank back and cleaned up , stripping down the extra braces around the tank so i can cut out for the glass , and even knowing the stand held the weight for a day , i added another brace all along the top braces under the stand , all my 2x4 on the top is being supported now , i screw and glued them down to my legs , but then put another set of legs to support it , so my legs are triple up now , it might be way over kill , have total of 32 legs 5 in each corner and the middle supprts got 3 legs each , they bundle togther ,( we all bundle lol had to say that from commercial lol lol ) anyway but its my life under the tank playing with filter and stuff and few extra 2x4 are cheap , just knowing there 4500 pds above me , and fact i made it , kinda got me worryed lol anyway i feel alot better now,,, ill show pic where i added more legs and extra brace along the top of stand and where i drilled my holes for over flows , i needed 2 over flow and 1 return and added another hole i plan on putting pvc pipe 3/4 to the top of tank , so for water change , all have to do is open valve and can drain , thats the thought behind it all
