| The size of the settlement chamber is not dependent upon the size of the pond but rather upon the flow rate you decide to run through the settlement chamber.
If you are planning on a single 4" bottom drain plumbed to the settlement chamber then you will need a minimum between 2500 gph and 3000 gph to sweep and keep the drain line clear. If you size only for that flow the chamber could be smaller than if you run a flow rate of 5000 gph.
That said, I will use the personal example of my pond to say that if I had it to do over again I would have a larger settlement chamber to get more efficiency.
If you decide to go with the minimum flow rate through the settlemnt chamber you can get the total flow rate and total turnover rate up to where it needs to be by using a seperate submersible pump flow loop based off the skimmer. |
