Thanks guys, I'm glad I read this first. I have 3 jugs of distilled water mixed up with 1/2 strength nutes but I'll save those for the next water change. I wish I could find a store locally that has stuff like calmag, superthrive, and liquid karma but I suppose I'll have to order it online. I should start a hydro store around here.

I like gardening in the yard and I REALLY like doing this hydro thing but half the time I'm setting here thinking that it's never going to work for me.
