larger skimmer for raising ph?

I currently have a reef octopus 1000sss and ran my airline outside to help raise my ph and it is now between 7.9 and 8.05 which is better then it was but my question is would a larger skimmer with a better air draw help more? My alk is at 11 dkh and cal is 440 and was lookingat getting a octopus dc skimmer thanks
