Will the floor hold?

Im thinking on upgrading my 90 to a 150 gal,my question/worry is will the floor hold the weight,no basement,its a crawl space,and what size pump should I use for this size tank..any info would help,if I do this I will be getting the tank this weekend. :D
 
As far as the weight is concerned, it's hard to say without seeing it first hand.

If you go perpendicular to the beams so your crossing multiple beams and NOT Parallel where you are on only 2 beams then you should be ok.

As far as the size of the pump. Are you going insump or external pump?

I got to the part where he said it would get worse and tuned out. Whew. That's a 3 sitting read, I think. Maybe I'll read more tomorrow.

If it's a crawlspace, you can just reinforce it really easily.

Go to home depot or the like and buy a 4x4 or two, cut one section to span 2 or 3 floor joists, one to sit on the ground and one a little bit (like 1/8 or 1/16th) long er than the space between those two and you're set. You can even do that in a few spots under the tank if it makes you feel warm and fuzzy inside.

:)
 
would you feel comfortable with a king size waterbed in your house? if so, i wouldn't worry so much about the tank.
 
I had some issues with my floor...

Does the floor "feel" solid near the current tank? if you step hard or jump by the tank does it feel solid or "springy".

I had a 72G in my living room and the floor would feel springy... after a year or so I could tell some doors near the living room were not closing as smooth and it was due to the floor sinking 1/2" 3/4".... long story cut short..... I sold my 72G and just recently placed 3 columns in the basement supporting the living room. I was able to jack-up the floor about 1/2". It now feels solid I can jump around pretty hard any the other side of the room doesnt even vibrate.

My tank was placed in parallel which is really bad since two bean were taking the brunt of the weight. My home also had some issues with the beam supports that why the whole deal began and progressed that quicky in a well constructed home this should not had happened.

Well thats about it from me ;)

I took a few simple approach. Since my sump is in the basement right below, I just mounted a 4" x 4" x 6' and got 2 jack stands. So there is a beam going across the support beams being held up with 2 jack stands. $40.

I wasn't worried about the floor collapsing, but I live in a 1927 Dutch Colonial. There was no concept of subfloors then, the wood floor is directly moounted on the beams, I just wanted to prevent floor sag.
