Where should I be earning??

I currently use adsense on my forum which has around 3000 unique visits per day. The problem is that with adsense I have a massive amount of page impressions (188,574 last week) and around 300 clicks in one week and earn $23.79. I feel that for 300 clicks and 3000 uniques I should be earning more than 25 bucks….it’s pretty darn standard.
Yesterdays stats:
Page impressions——Clicks———Page CTR—-Page eCPM [?]—-Earnings
28,959—————–53———–0.18%———$0.09———$2.71
53 clicks and I earn $2.71 :S
Is there a better advertiser I should be with? Keep in mind that I don’t want to send out adware…
Please help
