sgminer mining pool hub HELP

I am trying to mine Digibytes from miningpoolhub on the Digibyte-Groestl Pool. I downloaded sgminer from the suggested site on mining pool hub and when I start up the miner it asks for a server address which I entered as ---- stratum+tcp://hub.miningpoolhub.com:20499. Then I put in my worker name etc. Then it asks for the algorithm and I have tried to put in multiple things for this but nothing is accepted and it uses cklivas.cl kernel. What should I be entering for this? Any help would be appreciated I have been trying to set up a few miners the last few days and after days of trial and error I have decided I would like to mine this particular coin in this pool. Thanks allot for any input you can provide to assist me in remedying my issue. Basically I just need to know what to type to make it recognize I want to use a certain algo...Thanks again
