i got a 90g tank right now.and i plan to get 1 more 150g.but is it too heavy for the floor?i live in apt. 6th floor . the floor is 2x8inch bin and woodfloor.no concrete. here is a pic. the green line is the bins.sorry for the bad drawin.and the space betwwen 2 tanks are 3 feet.

I strongly recommend contacting a structural engineer. Have him or her evaluate the situation first hand.

If there is no concrete in the construction of the floor then the answer is NO FREAKIN WAY!!!!!!!!!!!!!!!!!!!!!!!!!!!!! No tank should be going the length of the beams as well, turn that 90gal the other way so it's resting on more of the beams. The tank should also be up against a load bearing wall. P.S. get insurance.

Most apartment complexes have rules against tanks over a certain size. Check with management so you don't get evicted.

I have a 65 gallon in my condo. You can get a 90 but dont get a 150 , I mean if u get a spillage from that 150 tank , wow , its gonna cause some damages. And dont put your intakes all the way down just 5 inches away from the surface , that way if your canister leaks it wont suck out all of the water !

I keep a 90gal in my 1st floor apartment, load bearing wall, and across 5 beams. I even reinforced the floor below with a few 4x4 posts. I would ask your landlord first.

taoyeah, I live in a similar 50 year old 7 story wood floor building as you.
I would not do more than a single 120gal tank in the same room, so your
plan for 240gal of tank near each other like that is dangerous. I'm sure
you got a nice deal on that 150gal, but you simply can't accommodate it.

a water filled 150gal tank is equal to the weight of 14 adult men standing
24/7 in the same space that 7 people would normally require. you can do
that for a few hours at a new years eve party, but not 24/7 for Months.
(including stand, gravel, fixtures, etc, you need to figure 20lbs per gallon)

you MIGHT be able to get away with the 150 alone if it's a wall between
apartments, hallway or outside, not a wall between rooms in your space,
and of course it need be flush with the wall to effect the most floor joists.
you should also reduce weight by using a light substrate like SMS, and
use driftwood and lava stone instead of dense rocks for your decoration.
but even with all these precautions, I still would not do a 150 at all, and
even downsizing to a 125 is pushing your luck.

thank you for the info so i amnot going to get other tank.

Yes you can it just has to be a 10gallon

see if you notice the tank is no longer sitting level...the floor will start to bow.

Two essential words here: renters insurance

i have a 46 bow front in one corner and i just bought a 115 gallon for the other corner. i filled it a week ago . i live at the 1 st floor and i also have wooden floor . after reading this i started to wonder
bad ideea?

same wall or opposite corners? If its opposite I wouldnt worry, if its same corners Id be concerned of proximity of two tanks. Get in he basement and reinforcepossibly? Of its its no basement then you shold be fine.

All I know is that drawing up top is HILARIOUS!! Not trying to be a d!ck, just, seriously, it made me smile!

one is in the corner the( 46 )
the 115 is on the opposite wall in the middle.
i just calledc the ap complex and they said is gonna hold
