Hear YEE, Hear Yee, Let it be know that Big Jake is now a honarary member of the "Pondboss Test-Kit Challenged Club". Fishman as you well know the instruction say to invert the ample after the color change. My Alkalinity is now 30. I should add that there is actually 3 of us that cant read and the other is the lab manager at at major chemical company who runs test all the time. I guess it makes me feel a little better to know he missed it as well. Fishman, You da Man.
