DIY Reinforced Floor

[ReefDreamz]

What do you think of my floor reinforcement? The tank is about 137 gallons and will weigh about 2000 lbs. It will sit directly above joists 2 and 3 but the front and back will be within about 6" of joists 1 and 4 as the picture shows. There is a 2x6 wall directly under joist 1 which is a sistered joist. There is blocking in-between all the joists. I went with two 2x6 beams consisting of 3 2x6's glued and screwed together. The first beam spans joists 1-4 and the second spans joists 2-4 because the wall blocks the second beam from reaching joist 1. One jack post holds up each beam and sits on a 1/2" steel plate placed directly on the concrete slab. The beams are placed about 5" in from the edge of where the tank will sit on the floor above.

I'm not a structural engineer, but it looks solid. I'm curious - what's with the red line?

Thanks! Its just the color of the flooring tiles. I went with mostly grey with a red accent. I painted the steel plate to match.

Gotcha. Red = my fish room.

Danger zone, potential location where tank will fall through floor.
Looks solid. Don’t have any concerns.

It's like the splash line at Sea World. "You will get wet beyond this point".
