Perhaps relocating the sump would be a good idea to reduce the load but I really don't see a huge threat.

Please see my new sketch because my memory served me wrong. The beam actually runs from one green post to another green post and it stops at the left green post.
The space that is underneath the tank is reserved for another big fowlr tank that I plan for future, so the sump will eventually move down to basement. Therefore i don't want any post underneath the tank

My new calculation is from wall to LVL is 17.3 feet. the tank will be 1.8 feet from the wall. And it will be 10 feet long so about 5.5 feet from the LVL

If this is true, and the tank is not sitting directly on the joists, I'd recommend you sister those joists far enough under the tank so the plywood doesn't deflect and fail. Plus that would take out your tiles 
There is a formula for sistering, but I can't find it on the web right now. |
Hmm sistering joints which means i have to move current plumping and heat ducts that are currently between those joints.
Here is my latest sketch
