So I went out today and bought me some pickling lime and some vinegar. I have 130g of water in my system. I have about 7g of water in my ato system full. I purchase my Rodi water from the lfs in 5 gallon containers. I grab 15 or 20 gallons at a time. So how do I mix it up. Should I grab a tub or can that can handle 15 gallons of water put a power head in there and mix like that. Idk. I could do something with a bulkhead and a ball valve for a drain? Keep the drain a couple inches off the bottom of the tank? I'll be making the lime in the basement and putting it back in the 5 gallon jug to put in my ato tank. I guess I'm just looking for easy ways to make it than transfer to my ato.
