I am mixing MRS. Wages lime with RODI water in a 5 gal. bucket ahead of time and then pump it into a resv. for ATO application. my questions is at the mixing bucket...there is slurry at the bottom of the bucket, can i just add more RODI and stirr for a future batch or do i need to toss the slurry and start from scratch every batch? if adding more water is fine does this affect the concentration of the mix over time?
