You might want to see the other thread for questions on touramline and the others.
ADA has a new type out now, a few folks have just started using it and they have done away with types I and II.
I like type I, have never tried II, but some have complained about II.
ADA responded to this by developing the new version and it's will repalce both products now.
ADG( Houston TX) has considered a refund of sorts, perhaps a reduced rate etc for those who had troubles with II and want the newer type.
I found this to be very generous of them, as ADA will not replace the product on their own.
I do not like the powder, it's like dust and replanting it is troublesome for me. It ends up all over the place.
Like others, I have have tried the other products with and without and never found any difference I could ever discern.
I do suggest and recommend ADA AS however.
So no one can accuse me of being a hater, but also not being an ADA Fan boy either. I try and be fair.
I do not sell ADA directly, but I do use for my client's tanks if I can.
ADA and their vendors obviously will try and sell you the entire line and tell you the marketing stuff to get you to buy.
This is understandable and is business.
Dupla did the same thing 20 years before ADA.
Dennerle does it in Europe. They must have a little bottle of juice for nearly every possible cure all.
And someone else in the next 20 years will as well.
My thing is finding what one thing or set of things that really helps make aquatic plant horticulture easier for the hobbyists, not just make $ for the businesses.
I'm in the business as well, but I need to be fairly sure I can defend and sell it before hand. A good product sells itself and needs no or little defense.
Penac? You have to have a great deal of snake oil belief for that to fly.
That's just outright crazy talk.
I think ADA As would work nicely in the non CO2 approaches also.
Hopefully more advanced CO2 users will go back to the basics and try this.
