* Sand is not a good substrate for plants. Too fine - aeration problems; surface to volume ratio not good. Anaerobic zones will form. Denitrification with odor will stress  plants and fishes.<p>* No dedicated biofilter. Nitrification bacteria will form and live on the sand. Tight coupling between fsh tank and grow beds. No way to decouple when one or the other has to be maintained.<p>* Fine mesh preventing the sand to get into the fish tank will clogg with detritus.<p>* Grow beds will clogg with detritus after approximately one season.<p>* No sump tank. Water level in the fish tank will vary a lot. Fish don&#x27;t like that. Stocking density will have to be low to aleviate this.<p>* Too much sun on the fish tank. Most fish species don&#x27;t like this and algae will form rapidly.<p>Please do not _sell_ aquaponic designs like this one.<p>I&#x27;m doing aquaponics since 2012 and I&#x27;m currently working in aquaponic research for a university.
