WOW.. What a thread. My eyes and brain are killing me now. Good info though for sure. Now for my darn questions.
Real small muddy pond (turns this way after spring every year from runoff on hill) I am in the process of diverting the makeup to be JUST the spring on the hillside and the ditch will be bypassing the pond soon.
Anyway I read this thread (probably missed some things) and bought some Aluminum Sulfate and some lime (gray powder) (and granular lime white)I think. Anyway I'm testing this in a 5 gal bucket and so far neither lime will stablize the ph drop after adding 3 oz aluminum sulfate and 3 oz of lime. The water turns gray with the gray lime and the granular doesn't hardly dissolve.
My question is what is the exact kind of lime I need to keep my ph in check? I hope to make this pond nice soon. Thanks in advance.
