I need a refractometer as well.. forgot to add that to my list, but I'm nooo where near adding livestock. I figure the rock will take a month or so to cure, I'm not in a huge hurry since I have so much to prepare... and I have a crap load of other projects since summer is around the corner... Like building the shed we just bought, building a garden to plant all the herbs and veggies I just bought.. photo shoots two weekends in a row.. not to mention the everyday things around the house..
I'm with you on the RO system, and I have one already.. just need the DI to go with it. We are also looking at getting a water softener. Good Times!
Ohh.. and we just found out my wife is Pregnant! YAY!!!!!
