Hi, Nikolay,
In the recent thread on the Amano tank stats I queried Penac but no takers. Seems that it is not in use in the USA. It's easy to talk plants because one prunes, plants, replants them day-by-day. But when it comes to substrate issues such as Penac in the substrate the once-a-year-maybe dealing with substrate issue is not at the top of the mind. Once it is in there, it's in there and there is not a lot one can do about it without a complete tear-down.
Anyway, Penac, that link was the best that I have found (a South African link I think). I was wondering where to get some Penac in the USA. I would like to give it a shot.
