I normally just back up to an ocean, throw in a long hose with a bilge pump attached and pump 40 gallons into my Jeep.
Most ocean water is free.
I back up to my driveway and pump the ice cold water into a big vat. Then I fill 5 gallon water cooler bottles with hot water and float them in the vat to warm up the seawater.
While I am waiting, I may dance.
Then I pump the water into 5 gallon containers that are placed on a table next to the tank.
I remove water from the tank and dump in the new water.
I could just pump it in from the Vat but that takes to long and I am impatient and always want to go and do something else. Maybe bungee jump or cut my toe nails. ;Bucktooth
This week I collected 140 gallons of water and changed 80 gallons in my 125 gallon tank.
I just wanted a few more gallons so I put on boots and quickly collected a little more. I just can't get enough.
