RowaPhos or PhosBan?

[Johnny Reefer]

Just wondering if one goes farther and is more cost effective than the other.
I think they both probably do the same, essentially, but I have a hunch one goes farther than the other.
It's so hard to compare.
One is wet, the other is dry, and thus measures differently, by weight.
One is measured in grams, the other mls.
How the heck are you supposed to measure a solid substance in mls?.....
....and what is the equivalant of the dry gram product to the wet mls product?

Just hoping a consensus will enlighten me more on this, and help me to reach a decision on which one I want to settle on.

Thanx much,
