Tilapia love eating bacteria aerobic AND anarobic. Tilapia will bring the oxygen to the detritus by rapidly swimming/swarming an area they wish to eat at. The combination of the tilapia circulating oxygenated water and browsing and exposing new substrates, aerobic bateria colonies will form and flourish....vastly speeding the decay prcess Aeration will most assuredly speed the decay process also.
Nathan, the tilapia will browse on detritus looking for the bacteria growing on it. The amount of muck they will eat will depend on what other foods are available and the numbers stocked. To get very noticable muck reduction, plan with predtors present, plan to stock 100#/acre or more. Personally, I would add aeration since the long term costs and benefits will be better on a budget.
