building a 500 gallon plywood tank

  • We are currently upgrading MFK. thanks! -neo
and my water test worked , held it , didnt crashed down , i filled it to very top , more then it will ever be filled and put my weight ( 185 pds ) and my woman weight which is 110pds ( real world 130pds,,,shhhhh lol )
 
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
 
trying to keeps things around here kinda laid back cause of tank and everthing , i spend hour to clean day , but house goes dirty in mins with everthing , woman hates it , but thats the way it goes , once i get the big tank up , the smaller tank 125 will be taken down , but for first few weeks will be right next to my big tank so i wont have to cycle my big buy
 
i drilled my holes for my bulks heads i went all 1.5 inch wide ,,, 4 of them , i drilled strait threw my stand, i was wonder what you all think about making the holes in stand 2 times bigger cause i can put my nut from the bulk head right to tank , instead of putting the nut under stand part ?
 
thats last set of legs were added after a build the stand and tank ,i used the wrose of my 2x4 on this part , i got 30 2x4 from the start and now only 1 left ,,,, i had to take the tank off and drill the legs to the other legs and then flip the stand and drill threw the top and bottom of the stand , tank is getting heavy and now with all the 2x4 on the stand , its getting heavy to move and flipp ,
