    Boric Acid, Powder or Granular?

    Does it matter which is used in the pool? I would think that maybe powder would dissolve quicker/easier, but is also more costly.

    What is recommended?

    Both kinds dissolve very quickly. At least one person has had a rough time using the powder, though others have not had a problem with it.

    I used granular and it dissolved very easily. I chose it because I thought powdered might clump.

    Thanks my searching mojo isn't as good as yours. I figured someone here had tried both, but couldn't find it.
