My thoughts on chambers....

I'm not sure if settlement works for you depending on the GPH you will be running. These chambers need to be large for debris to settle out effectively - which is contrary to your requirements.

If you aggressively aerate the 1st chamber, you can put your oyster shells there. The bubbling air will keep your shells free of organic debris. The first chamber should overflow into the second. This will keep heavier mineral debris like sand and shell fragments in the first chamber, whilst passing through suspended organic debris.

The second chamber can contain your pumps and UV tube (if you get immersion model)
Both pumps should go to the Ultima. If they are flowing too much, you can use a bakk valve to reduce the flow. The output from the ultima should go to the shower and returns via a manifold. Valves will be used to adjust the output. The bakki shower should get only filtered water. It is not a good idea to pump dirty water into a bakki. Muck will build up very fast.
