I am a fan of running water directly to the skimmer for the tank but know that most skimmers are best off at a flow through rate of 1.5 times the total volume. Thats probably around 200gph for your setup. I doubt that would be acceptable for the sump. You might look into routing some of the water from the overflow past the skimmer directly to the sump. |
With my current stand design, I may be able to use a four foot skimmer. If I can do this, would a counter current wood diffuser skimmer be as productive as the recirc needle wheel?
I was planning on splitting the line from my overflow and regulating flow to the skimmer with a ball valve - the ultimate flow into the sump would be regulated by how quickly my return pump was pushing water back into the main tank - correct?
Re: 200gph for the sump - I'm guessing that's too low? I was thinking of turning the sump over roughly 6/7 times total volume per hour, by means of the split overflow line.

There are many theories like Scott said Counter current skimmers tend to be very tall. Your Idea of splitting your overflow water is a good Idea for use with a recirculation skimmer. You can also modify a ASM or Octopus skimmer to be a Recirculation.

Is the point behind recirculating flow in the skimmer to give added contact time w/o increasing the height? I don't suppose running through a pump would "disconnect" dissolved solids from the air-bubbles?
Again, sorry for the barrage of questions.
Thanks a ton.
