I will say off the top, Im not saying their a bad choice, just that they haven't worked out for me. THATS ALL. Nothing less, nothing more. I don't think Joel is trying to make them a special "fix" he just chimed in to defend himself from those involving him in a discusion he didn't even chose to be in other than he has one is stock. So buy it already and see how it works out, all I was saying is make sure your tests are in order and the sea hair will clean the rest up, if you have high ph04, or silicates well your wasting your time, might as well buy him and roast him over an open flame... YUMMM
Regardless, where all here just to help, just as Joel is to help provide what you need, If you ask questions.. I'm sure you will get and eventual unbias answer.
