Found this product in the LFS
yesterday and spoke to the assistant about it. She couldn't tell me much more than verbatim what was on the bottle but did say she had the tank "out the front" that over a two week period had substantial growth. I had a look and if what she pointed out is true, it is a pretty amazing product.
But in reality unless there is something else going on with this product it really does seem to be nothing more than a combined buffering product based primarily on calcium.
Anyone got any views on this or experience? I'm ALWAYS cautious about using things like this and would appreciate your views.
