@ dennis - I'm no "health nut" but the wife is ..... are you saying that swallowing powered charcoal is a good thing? I've never heard of that! THXOriginally Posted by dennis
And, BTW, I use activated charcoal in my FTs to remove toxins from the crappy water we have - Chlorides, Flourides, and who knows what else I don't see that as being a bad thing and we also use zeolites, when we can afford them! We still run the water thru GBs to let the bacteria do it's thing. The charcoal does have to be replaced from time to time, but so what ..... so does the media if you don't want to put it into a self-cleaning oven to bring it up to 550F to kill any diseases, flukes or parasites that might be in the fish water.
@head rush - I once found a You-tube vid that showed a guy in Israel that was doing pretty much what you are intending to do ..... using reeds (I think that's about the same as 'cat-tails' here in Montana) to filter, and heal the water from his grey-water system - something we can't do here in Montana, because to have a pond, we have to get the permission of the state, county, city, and probably the Feds! .... I've lost all of my bookmarks recently, so I don't have it anymore, but maybe you can find it if you search enuff ....
Just my 2 centavos .....
