Interesting design, thanks for all the info.
Here is another idea you can add to your original drawing. It is a simple mod that allows you to regulated the skimmer out put, if the skimmer should take off and start over producing, so that it doesn't over flow all over the ground.
You don't need to have a special sealed container with a ball float valve as sold by many skimmer manufacturers.
I discovered this by accident.
I built a 20" high 4" pvc skimmate container with an over flow at the top that would allow the skimmate to flow back into my fuge in an emergency if i didn't empty it in time.
Out of my sealed Precision Marine skimmer cup , I took the drain and put a hose into the skimmate over flow container. If you extend the hose so that it is a couple of inches below the emergency overflow, here is what happens as it fills.
When the skimmate fills up to the bottom of the hose it starts to bubble. By the time it is about an inch over the bottom of the hose, it is bubbling loudly and making a very noticeable racket. An automatic alarm to empty the container.
But even if you don't empty the container, the back pressure from the hose in the fluid slows the skimmer production down. When the fluid level gets a couple of inches over the bottom of the hose, skimmate virtually stops flowing. It acts as an automatic flow controller.
Simple but very effective flow control, with a cheap alarm to boot. You will never come home after a long week end and find skimmate all over your floor.:rollface:
Your skimmer cup needs to be sealed and have a drain for this to work.
