200 - 300 reward/30 min at this bitcoin price is good and faucet is very easy to claim. You have to see how much money you get from adds and how much you can pay your visitors, and set rewards by that.
Referral commission is different thing, this is new faucet, you need free promotion from everybody, and you should give higher commissions, at least in start
hope this will help
cheers

+400/hour is good for an easy faucet like this one.
A lot of people asking for higher rewards just don't understand how it's difficult to run (and make profits) a faucet
