That would only serve to worsen your greenwater problems. I've had success in the past with barley for clearing green water outdoors. It's cheap. That's assuming that your discoloration is due to alga...not other compounds. If you're intent on using carbon (which I don't think is a bad idea at all), look into industrial stuff in large quantities. You don't need lab grade carbon...Each batch should last you a month or so, assuming that you are using large enough quantities.Fri, 01 Jun 2007 22:45:44 GMTdumbguyhttp://forum.marinedepot.com/Topic66864-30-1.aspxWell, that is the problem! I have a "spare" pond right now, we went bigger and moved the fish to the larger pond. But, the water in the small pond is so crystal clear....<br><br> Maybe I could empty it, fill it with water from the big pond, but we wouldn't know if the water cleared from the charcoal or from the biological processes in the pond....<br><br> What if I just used a white bucket with a PH pushing water through a bag of charcoal? Can you think of any other process that could be given credit if the water became clearer? <br><br>Tue, 01 May 2007 05:34:59 GMTSeahorse Whispererhttp://forum.marinedepot.com/Topic66864-30-1.aspxOK, I know it sounds weird, but why not? It must be activated to have the porousity to make it work? <br><br><br> ( I know that is not a word, but you know what I mean?)Sun, 29 Apr 2007 21:36:04 GMTSeahorse Whispererhttp://forum.marinedepot.com/Topic66864-30-1.aspxI am just thinking we could use it like we do in our home aquariums! It makes the water so crystal clear! But, seeing how we have to change it every few days to benefit, and the amount we need for out large ponds, it probably is not something we can do, right? I was just thinking where do water treatment plants get it from?<br><br> I did have this brilliant idea to use charcoal briquettes, but they are not activated...Sun, 29 Apr 2007 06:19:41 GMTSeahorse Whispererhttp://forum.marinedepot.com/Topic66864-30-1.aspxIs there a source of cheap AC for ponds?
