180 gallon on the main floor
 

hey guys was going to get my parents a 180 gallon tank and was just wondering would i need any joists or post put in to hold the tank up, there will be a sump at the bottom as well probably a 50 gallon sump not sure yet.

That's an absolute maybe. Or not. Depends on floor material, what is under it, load bearing wall, middle of room, etc

You'll be fine. Just make sure that it sits accross the joists, not parallel with them.

Mine is main floor, and there was zero deflection.

As long as the tank run across the joists and will be close to the wall where the joists can carry a bigger load you are fine,I have a 130 plus 30 gallon sump for a year now and the floor doesn't show any signs of stress.just go with a longer tank so you are spreading the load over as many joists you can..my tank is 6 foot and seats over 4 joists

Thanks for the tip guys.

The age of the house matters sometimes too.

Placing it across joists would be the best bet. I had my joists placed closer together than regular spacing and added 2 beams because I couldn't deal with the possibility of my tank ruining my house. You could always get someone (engineer) to drop by to see if it will hold
