The only valve I'm using is to drain sediment from the clarifier.

The reason I can't build it like in the book is because for several reasons I can't raise the tank.

There's a reason the set up is the way it is in the book Small Scale Aquaculture. It's a tried and true system and a KISS system.

Sorry I'm not trying to be a know it all. I've been there done that and tried different things and made all the mistakes. Additionally once you start adding too many gadgets to a small scale system it becomes an expensive hobby.

You are obviously free to do what you want and I'm just trying to help...
