Floor reinforcement ?'s

This is where my 90 gal is going. Centered on the wall. The nano is going bye bye.

This is the basement. The above pic is in this spot.

These are 12" joists running perpendicular to the tank.
Do I need to reinforce the floor? If so are 4x4's running from top to concrete slab sufficient. Thanks in advance.
 
From what I see it looks like its going against an exterior wall which will take a lot of the load off. If the joists are 16" apart and you can get the tank to sit on 3 of them Id think you wouldnt have any problems at all.

I was thinking the same thing. But I think I'm gonna reinforce just to be on the safe side.
 
You don't need to reinforce if the tank is along the outside wall. The load goes straight to the foundation.

If you DO feel the need to reinforce, you need to break through the floor (which is only an inch or two thick), dig down several feet and pour proper concrete footings. Otherwise the columns are just for show.

Seriously, not being lazy, you don't need 'em. Not for a 90, for sure.
 
With 2x12s @ 16" on center and perpendicular to the tank you don't need to reinforce the floor for 90.
On another note you need a new electrician and your insulation is installed backwards. LOL the paper goes towards the warm side, so in a floor cavity the paper goes up.

Also it looks like your house was built after 1950 so most likely your basement slab is 4" +/- thick. So if you wanted to add the posts you wouldn't need a footing for such a small tank. Older homes that have been retrofitted with concrete basement floors (they were typically just dirt) the slabs are very thin.

Yeah the previous owners had this basement put in when they put an extension on the house. The basement is only accessible from outside and they also did electric themselves. I'm guessing they did insulation too. I'm gonna get a new circuit for this tank only put it for that reason.

I really wanted to do a basement fish room but with the location of this tank it's just not possible.
 
You don't need any more supports. Those floor beams are fine especially since they are on the foundation. Like said before, just try to catch all three. You have the perfect setup for a basement sump!!!!

I wish you were right. That basement is under an addition that previous owners did on my home. It has no access from inside the house, only from outside via bilco doors. It's basically open to the elements.

Yea, but his wife would be questioning the presence of a pre-pubescent teen hanging around the house in a Robin outfit constantly saying, “Golly gee wiz Batman,” and Alfred, the English butler, incessantly feather-dusting that darn bookshelf.

Don't forget the weirdos in spandex who would show up to try and sabotage his tank through over elaborate schemes and dim henchmen. Then all of those words just appearing out of nowhere could cause epilespsy. Yeah I would not recomend it.
