How much water can u make/store a day.
To be able to do multiple 60gal water changes on 1 weekend Wow.
I have 2 55gal barrels but couldn't currently even mix one of those barrels to get get 50gallon of salt mixed.
Beyond mixing salt in the tank themselves. (Still need to get the mixing barrel set up with pumps or whatever crap is needed to mix and move water from one barrel to other. , I only have the one to hold the rodi water currently in use. I use a bucket to scoop water from that barrel to 5 gallon buckets and hand mix my salts. Don't have a way to mix salt in the other barrel I have yet beyond maybe a 2×4)
I can't currently fathom being able to change so much water multiple times on one weekend. Even if my other barrel was set up to mix salt water.
Takes me a few hours to even heat up 5gallon buckets of saltwater. Couldn't imagine how long to heat up 60 gallons in a emergency, right now it probably take me 24hrs unless I heated water on the stove or propane burner.
All that to say your setup has to be crazy efficent to go between auto water changes, to being able to do massive water changes.
Definitely something I would like to work out a plan to get to the capacity like you. Especially with my 210gallon in the works.
It's really pretty simple, you should be able to do it with your 2x 55g barrels. Mine are 65g but that's all I have. I stick a cheap jebao in the bottom of one to handle the actual mixing. And like Randy and Mike said above, I don't bother heating it unless it's like a cold winter morning.
Here's my mixing station:
Pump RODI from the right barrel to the left barrel, turn on the jebao, dump a bag of salt in the top, wait 5 minutes and check salinity, adjust, pump the water into the DT using the long hose you see. About as easy as it gets!
