Solana Skimmer Question!

[schwimmair]

I just got a used Solana yesterday and my skimmer pump blows out water but no bubbles. Is the pumps supposed to blow out bubbles if so can I do anything to it to have it blow bubbles or do I need to purchase a new one?

Thanks

does it have the air hose connected to the pump? there should be a hose that sticks above water level to inject air in and produce bubbles
