Mmmmm, excuse me..... but I find it odd (and not a little disturbing) for
one commercial vendor to dish a rival in such a manner. If he did indeed
have "problems", I would think that he should also have hard data to back up
the claim..... hopefully he can be persuaded to post that data..... From
what I can tell, Mr. Prescott is a one man operation, while Dupla is a
multinational corporation with a history of research and development. I'm
shocked to hear them mentioned in the same post....
Issues _have_ been raised about various ADA products, mainly with regards to
their expense. I have questioned the science behind some of the products,
especially in light of the connection with the Plocher system (vibrational
energy.....), but Mr. Prescott seems to be aiming his complaint in a
different direction. I have _never_ heard anyone question quality of the
various fertilizer products. Is this a real issue, or a red herring being
thrown up by a competitor?
No wonder there is a general ban on "commercial posts" on the APD.

Mmmmmm, maybe he is learning..... a search of the archives will show that
several months ago I asked him for some information about his products and
his response was an offer of a discount should I be able to persuade any
local dealers to carry his products..... (but I never did get the
information I asked for in the first place). I wasn't very impressed.

Yea, well, like I said.... maybe he is learning...

Mmmmm again....... may we have those references, please? Like Roger, I have
never heard of any problems with running a tank with elevated Potassium
levels..... if Mr. Prescott knows of any, I'd really like to know the
journal the study was published in....

Don't be too quick to worry about elevated K levels Roger. I've been dosing
Potassium supplements in several of my tanks at various doseage levels (one
in excess of 60 ppm) for well over a year, without any problems which could
even remotely be attributed to an excess of Potassium.

I'd be very interested in reading his answer to this.
I'd also like to see him back up his claim that ADA products are any less
effective when used correctly than anyone else's. It may very well be true,
but needs INDEPENDENT confirmation, not some slag from a business
competitior. If he can't back them up, I would expect a full retraction and
a public apology to ADA.
