Skimmer not skimming?

[drillsar]

I made a diy skimmer from here, It was working before now I cleaned the cup over a week and no foam?

I see bubbles but no foam what could be the problem?

When was the last time you gave everything a good cleaning? Maybe there is some kind of blockage or calcium build up? :)

Ill take it a part again tommorow and Ill see im getting good bubbles but no foam.. Strange...

Some DIY skimmers don't always work correctly. What design are you using? Are you using the right pump if you use one?

im using the easy as pie skimmer, Using a Mag 5 which supposed to work with this, I also have a mag 7 but didnt try that.

Make sure the design is right and you followed right messurements and everything. Not much you can do if its not skimming besides adjust it.
