The Puffer Forum

Yes, that I could understand. The wording in the previous posts implies that the product is not good for puffers though, not that it will cause issues with skimmers.

lay off the mela or pima fix as they are not the best items for porc puffers

I read it as being inappropriate rather than not good enough, and I remembered the skimmer issue.
By the way, I'm thinking of patenting "gakking up" as a viable technical term
Pami.

I guess we'll have to wait for Jager or Kman to respond whether it is because of "gacking up" (copyright 2005 - Pami) or some other issue that makes P&M-fix unsuitable for puffers. Until then, I will keep a gallon of each in my medicinal chest and continue recommending use of these products when appropriate.
