Gareth, with 6.2 PH, Aglime is a good thing. If it were me, I would add the aglime and do a settle test (simply go take a sample of water and see if it settles in a few days, I think the experts want you to place the sample in a darker place, but I can't remember that part). If your sample will not settle naturally, alum should help.

As I understand it, pelletized aglime will not have the effect you want. I use the powder version in my ponds.


Tell us about you pond, size after the re-dig, shape, depth, kinds of fish, your goals for your pond, ect.
