Thanks guys: Checked the Ph at 8:30 this am and it was in the 7.9-8.2 range, (compared to over 9 at 3:00pm two days ago), so it is truly a moving target. My alkalinity was right at 60ppm, exactly where it was during the test two days ago. I think I'll keep monitoring it daily at different times of the day, and if this Ph thing seems to fluctuate in the 7.5-9.0 range, I'm not going to "fix" it. To answer the stocking question: I'll be putting in about 200 BG, about 150 RE, and about 10 lb of FH (300 per lb). Next June I'll add 50 LMB as 1-3" fingerlings after the BG and RE have spawned. Sound OK???? Guys, have a great week end. Jimmydee
