And yeahhhh, my response on the regular use of PP... wasn't a very popular fellow...
One idea that I hadn't heard of is that people will backwash their pond into a vessel, PP the crap out of it, neutralize the PP with hydrogen peroxide, and then use that for the next water change in an effort to conserve water... Any thoughts on this?
I don't think it's good practice because I'm not looking for dilution when I do a water change, I'm looking to add the minerals and such that have been "used" up in the water I'm taking out and to get rid of any pheromones that may prohibit growth. (not sure if it's pheromones/hormones/"no-grow" juice... that stuff is a bit over my head... but you know what I mean)
