Thank you for the input Dave. I don't believe that it is a matter of noone trusting you to know your facts, I think it is people being nervous nellies about the concept that a sedan is sitting in our living rooms but is made of water. Though you are likely correct, we may just still reinforce a bit. Thank you again!

Jon, I'm not sure what you mean by the 2 triple-layered 9.25"lvls. But I am interested in more details. Origami, I would hapily talk to DaveW. Thank you all for the suggestions!

Hello folks. We are getting back into salt water after a several year break. After a lot of discusion we have decided on a 300 gallon tank. As the basement is the reason we never got back into our 150, because it is not where people are, we want to put the tank on the main floor. From what we are looking at we will be doing the plumbing down into the basement and plumbing it back up to keep th volume down a bit. This means that we are looking at a bit under two tons of weight up on the floor. Facts about the floor: 16 inch offset on the joists 2 X 10 joists resting upon the main structural support beam. No finished ceiling in basement. The tank we are looking at would have a 6 foot by three foot footprint and would be up agianst the main loadbearing wall. I have been looking at adding a pair of jack posts supporting a length of 2 x 10 that would be running perpendicular to the joists just outside of the footprint of the tank. Thoughts and suggestions? Thank you
