My wife is the director of aquatics at our local indoor facility which hold 480,000 gal of h2o. With her degree in chem., minor in biology, and 7 years experience balancing alkalinity, ph, acidity, etc., I've got a built in "expert". All she needs to know is how all that relates to a "pond" with fish, instead of a "pool" with a bather load of 400-500 people per day, hee hee!! I think she'll make the transition well, cause she's my crappie fishin buddy also. We are going to begin water testing this weekend and as we make progress, and add chems etc, I'll give yawl some feed back, for what it is worth. Feel free to jump in with suggestions. Gonna be fun..
