In general, bars spaced 16 inches in the center can be stretched 1.5 times in depth in inches. A 2x8 at 12 feet, 2x10 at 15 feet and 2x12 at 18 feet.
A 2x12 double beam can span 12 feet, one (2) 2x10 can span 10 feet, and so on.
A 2x12 can carry around 180 kg. per foot or approximately 2100 lbs.
Subject: 20 feet of beam clearance, in this case you need something like 1216 glued laminated timber or LVL to stretch 20 and you can only use 2x810 16OC dimensional timber as the beam.

In general, spokes 16 inches apart in the center can extend 1.5 times in inches deep. A 2x8 at 12ft, 2x10 at 15ft and 2x12 at 18ft.
per square foot for areas in the Northern United States. For high traffic parts, this could be 50 kg. per square meter. Multiply the load per square foot by the square footage of the area the beams will have to support. Divide by the number of beams to be installed to get the load per beam.
A 2x6 triple beam over a 3 meter span should be more than enough for a normal deck load.
For example, a 2 × 8 double beam can span eight feet. 0 inches if the deck joists are 6 feet long.
Some of these get quite technical and mostly involve pounds / square feet loading. 2x6s are mostly used for farms, especially since you said 24 oc and they really only have short spans (5 or 6 feet). Most floor loads are at least 2x8 @ 16 oc and preferably 2x10.
A 75 is 48 wide, if you go around the bars it will take up at least 3 bars. The tank weighs almost or more than 700 kg. Most floors in newer or older homes should easily accommodate a 75 gallon tank!
Older people are taller and therefore carry more weight. I would also say that a 150 with sand, stone, filter and backing is too heavy for a floor that is not supported by additional concrete or joists. A floor must be able to support 40 pounds per square foot to be safe for a single family home.
For example, a 125 liter tank on a wooden support perpendicular to the joists on a load-bearing wall would often be suitable without additional structural support. If your tank exceeds 125 gallons, consider adding supports under the hardwood floor.
The answer is almost certainly yes. Remember that a wing can weigh 800 lbs. There are also about 5 wide loads, and depending on the piano, it is 6 to 2.4 meters long.
So yes, a rated load of 40 pounds per square foot means the floor can support 40 pounds on every square foot of floor.
If you divide the weight over 3 bars this means only 100 kg per bar (very doable). If you are concerned about possible bending, you can distribute the weight more over 2 screws per beam, so only 50lbs per screw (very doable).
