You have google adsense I don't think you need any other ads network to manage your faucet. google adsense is enough. you just need to work on the promotion of the faucet and get good traffics everyday.
one suggestion give small reward and reduce the time. I see some faucets pays 100 satoshi but the time between claim is too many hours. like 6 to 8 hours. I think it is better to give 50 satoshi and reduce the time to at least 15 minutes. with this more people come into your faucet.
one more thing, I think you are only investing to pay users you didn't spend anything on faucet design and layout. better to do little work on your faucet also. a custom faucet gives you more benefit instead of a random API.
One pop-up ad and a bunch of banners are enough, imo. If you want to get loyal visitors, don't put a thousand ads that would take you 10 min to close. You need light but profitable advertising. Try to send your faucet site to different rotators and faucet lists, that might boost your visitors number.
Also, a lot of people are using AdBlock. That would mean 0 earning for you; implement some anti-adblock script on your site.
Best of luck!
Pop ads are not recommended at all, never ever use pop ads for a faucets.. with pop ads you can't get good revenue but all your regular visitor will run away. google adsense is enough and perfect. and google adsense don't work with pop ads. if you need your adsense to be banned then surely use pop ads.
