Media-based Aquaponics Systems
If you’re already using a media based system, then solids probably won’t be an issue for you. If problems with solids do arise, it’s likely that your stocking densities are too high or your medium is too fine. If your stocking densities are too high, you’re be producing more waste than your media bed can break down. If the medium itself is too fine, then the waste can impede the flow of water through your bed, clogging things up. When this happens, the waste decays rather than being broken down quickly. Decay consumes oxygen, so decaying matter will cause your water to be anaerobic. This is one reason why it’s important to use larger media sizes (not pea gravel or sand!). Our media is not dense (93% void space), so it allows water to travel freely through the material, even when there are lots of solids present.
Raft Systems in Aquaponics
If you have a raft system, then you’d better invest in solids removal equipment. This reduces the overall nutrition in your system, but if you have proper mineralization tanks you can still maintain relatively high nutrient levels.
