  1. how to take out the solid wastw from a rectangular tank??? can a pump do it or should we do it manually????
  2. Without being to scientific or trying to prove yourself, could someone give me a basic break down of how a true aquaponics filter would be set up. not a high tech one, but one that is for a small set up of 200 gallons. my solids are clogging my drain. i have a flood to drain bed above my tank and the solids are plugging the return hole. i have drawn up many different ways, but dont want to waste my time. any tips?
  3. One problem with media beds is that they need to be taken out of service to clean. If a person could identity bed zones that were trending toward becoming anaerobic and perform “targeted†cleaning, the bed could stay in service with minimal harm done to the biofilm. One way to perform such trending is to profile the solids layer with an ORP probe on a monthly basis and record and chart the results in a spreadsheet. The following illustration can be used as a guide for interpreting the results. schematic presentation of flooded soil from Y.Chen and Y Avnimelech
  4. Today, I would like to present my latest solution to solids filtration and a short evolution of the path that led me here. This solution is cheap and effective...well, so far anyway. Please send comments, bets on its success, and/or thoughts on improving it. gRobot System 1.0 I began my aquaponics project with the kids in March of this year. We built our raft system with fill and drain grow beds and 3/4" pipes throughout. My initial system had no filtration at all. Solids began collecting in the growbeds as expected. Since the plants are in drain pots willed with gravel, this was not a big problem. But soon the roots of my plants were coated in solids, which inhibited growth. Here is a pic of one grow bed (copper and poly modified Afnon syphon on the left) http://www.aquaponicshq.com/forums/album.php?albumid=31&attachmentid=2602 gRobot System 1.1 In June, with green and messy water circulating, the plants looked great but the fish were eating less and less. Nitrates were begining to increase. So, I decided to add a simple filter to the supply of each grow bed using available materials. These included drain pots, gravel, and an old t-shirt. Improvised cotton and gravel filter using drain pots http://www.aquaponicshq.com/forums/album.php?albumid=31&attachmentid=2975 The improvised filters worked surprisingly well. However, this is intended to be a low maintenance system. And these filters exhibitied 2 fatal flaws from my point of view.
