And just one more question...what happens if you use steel 44 gallon drums filled with water for weights...since the volume is the same as the weight, does this just completely cancel it out and the actual underwater weight is only the steel or is there some other calculation for this scenario?
Thanks Bystander...so I'm thinking of the 2:1 principle or something like that... but it doesn't apply in this situation because it's a single pulley purely to enable pull from another direction? (so essentially the pulley isn't there and I'm just pulling a direct weight).
If this is correct...

I need to submerge a 2000L plastic tank (circular and approx 1.5 high) and then release it to make it...
