With showers or ponds that use showers if you have an area of space that allows some degree of settlement the fines will always settle there even if you have great volume turnover this will affect the clarity of the water.
The whole concept of a
proper bakki shower pond is there is no where for the fines to settle ie pond floor is sloped to the bottom drain. Bottom drain is connected to a small pump chamber using a submersible pump that sucks from the bottom of the chamber there by preventing settlement and up and over the showers. Obviously there should be the right amount of media and appropriate flow rate, not too slow and not too fast. For every 1 ton of volume turnover you should have 4 to 5kg of media. That is for the most optimum setup, for eg 10 ton pond with 30 ton turnover (say 24 ton through bottom drain and 6 ton through skimmer) with around 120 to 150kg. A simple and elegant system (saves money on building too

Lets see 1Kilogram = 2.2 lbs. and 1 ton = 264 US gal or 220 UK(Imp) gal
