MRC MR3 recirculating?

[LawnTodd]

I'm building an MR3 reciculating skimmer and I don't know the lenth of the six inch tube or the lenth of the four inch tube to the top of the collection cup. If anyone knows the lenths, please let me know.
Thanks
Todd

Go to the Lighting, Filtration and other section. Look for MRC club and post there if you want. You may have better luck. Otherwise contact Andy directly at My Reef Creations since he is a sponsor here. My advice would be to find out the size for a guide then build it as big as you want.
