I am looking at a modular home that has a crawl space beneath it. At some point I want to install a rather large fishtank. My question is, as salt water weighs 8.5 pounds per gallon and I want a 180 gallon tank, what is the best way for me to reinforce the section of flooring where it will sit so that it can support that kind of weight indefinitely? Obviously, concrete would be great. But can I pour concrete into a crawl space beneath my house without causing other problems?

You are going to have to add a footing. I do not know where you live, but the footing must extend below the frost line to avoid heaving. It can be a pre-cast footing if pouring concrete under the house is difficult. I would think that digging the hole would be the most difficult part. Place blocks on your footing, and pier up to the bottom of your framing. You may need to add some blocking to the floor joists to distribute the load. You should use a termite shield between the pier and your framing, if they are a problem in your area. This is not an enviable task, but a big tank will be your reward.

Beef up the joists. Then use concrete blocks with 4 inch solid ones on top. You may need shims. A couple of hydraulic jacks would help to to apply pressure to get a snug fit.

get concrete blocks that are used for decking and 4x4 on top of that and shims, all under the joist.
