Yes, the garden hose is your limiting factor. I bought an adapter so I can use the 1.5 inch pool vacuum hose. You remove the 3/4" hose adapter from the submersible pump. My pool is 25,000 Gallons and with 1/3 hp and a 1/6 hp pumps running I can drain my pool in about 12 hours.Maybe this is worth another thread in a different section, but I measured 6GPM with the recommended Superior Pump 91330 1/3 HP through a 5/8" x 50' garden hose.
That's some 38hrs for a 80% water exchange... is there something obvious I'm missing that is bottlenecking the pump more than would be normal? Is it perhaps worth grabbing a couple of the 25ft 1-1/2" hoses? (I need a 35ft run) .
Some places make a flat hose, like a fire hose, that can do the same thing. Sometimes called a backwash hose. You may need hose clamps and adapters to make it work.

My two pump setup. The 1/6 hp pump has the 3/4 inch garden hose.
