2nd riser tube lenght

[mungus]

I am wondering how long I should make my second riser tube. The main riser is 6.5" ID x 21". The tube I have for the second riser is a 3.75" ID. It is going to be a single beckett skimmer run with a blueline 55.

Thanks

I am thinking I should go with either 6" or 8".

Is there anyone with an MR2 or MR3 that could measure the second riser on their skimmer?

Thanks
