reinforce flooring for a fill test?

Hello; here is the web address of an article that talks about the issue.

There is not enough information in your initial post for someone like myself to give a sound opinion. My take is that it is best for someone with some knowledge and understanding to actually have a look-see at the actual structure and it's current condition. With the tank, stand, substrate and other stuff a 300 gallon tank might weigh up to 3600 pounds.

Good kuck

Hello; In my current house some of the floor joists had been compromised with large cuts. I had to sister additional joists in place. If you watch Mike Holmes TV shows you may have seen episodes about new construction with serious structural issues.

In case some missed this thread a while back here is a link to it. A look at the pictures should give pause, they did for me.

I am not sure how the fill test being short term ( 36 hours) will be of benefit if the structure cannot hold the weight? Perhaps some sort of temporary bracing under the floor during the test.

If you own the house, then the risk is your call. If it is someone else’s house, then perhaps a good renters insurance policy for the possible damage?
Good luck
