    Helo all

    My question today. does a bigger skimming surface make a difference in water quality? and what type of overflow works the best.

    I would like you to share some of your thoughts on overflow designs and maybe a few pros and cons about the design. Also, what other types of overflow designs are available. I know of corner overflows and center overflows. Is there any other designs?

    C2C = Coast to coast, an overflow that skims the complete length of the tank, works well but requires the over flow to be 100% level and generally must have a high flow rate for it to flow over the complete length.

    check here for a calculator to determine overflow width.

    Calculating overflow width - Pumps and Waterflow

    As it turns out, even if a 50mm pipe can handle 6000L/h, the linear length of the pipe is to short to allow that volume of water to enter.

    Looking at Sentari pcture. Must measure the length of the overflow. And that must fit to the return pump size. In his design the 50mm pipe is below the water surface in the overflow box, and should be able to handle a big water flow.
