Those TGI joists also calle silent floors are extremely strong think of your wifey saying she weighs 130 pounds not very big she walks around the hous in heels ..... Every step all 135 pounds goes onto the heel which is say 1/2 diameter that's 270 psi on the plywood floor..... She doesn't fall through

but she doesn't stand in the same spot for 365 days of the year

Or does she?

yes yes I know it won't make a huge difference either way, but in principle I think 1000+ pounds in the same spot over the course of 365 days or more will eventually make a difference. But I'm not a builder so what do I know.

So in other words... I shouldn't have anything to worry about?

that's pretty much the general consensus that I got out of my thread and now yours as well :-)

Just hurry up so I can buy your old tank.. since Josh won't sell me his.

Sweet, well i guess its a go than. I'm probably going to start on the stand in 2 weeks.

lol its going to be a couple months before the tank goes up for sale. Need to get everything together for this one.

If I were you I'd have posted asking about a 300 gallon. Then people would have said 150 was safer and we'd all feel great lol.

Build ON!

What are the I-beams spaced at(19"centers)??? Make the stand with a wide ledge(like 4-6") around it to distribute the weight over a wider area. If you can get the weight over two of those I-beams then Bob's your uncle.

I can relate to this problem, my 75G isn't going to be see water until we move house to somewhere where the joists aren't 2x6 or isn't rented so I can beef up the floor!

I think that's the way to go if you can't beef up the floor. If I remember correctly it said somewhere that the tank was going to be over 20" wide, so if they're 19 and a bit" centres, you're hitting two for a start, a 10" ledge on each side means you'll hit three. It could take some careful positioning of the stand so you're actually over the joists themselves and bearing directly on all three. The subfloor should also help to spread some of the load to the rest of the floor.

Given that there's access to the joists, the manufacturers name is usually printed all over them, so you could try and phoning them. If you can tell them how many joists you're over, what the load is and how far out from the bearing walls and/or centre beam of the house they should be able to tell you if it's OK or not.

Just my $0.02
