Hello everyone, I am looking at this absolutely stunning page here: http://showcase.aquatic-gardeners.org/2003.cgi?&op=showcase&category=0&vol=3&id=73 I counted 11 large healthy spawning discus fish which means they are being fed good quality live food so I think. And on the other hand I don't see too many fast growing plants. And I would like to know if this is the case where the Nitrate is accumulating or decreasing. Does this system use many water changes, constant water changes etc or is there a natural balance. Thank you, Aviel. ------------------ To unsubscribe from this list, please send mail to majordomo@thekrib.com with "Unsubscribe aga-member" in the body of the message.
