I’m not getting any foam production in the collection cup of my skimmer. Why?
There could be several causes for this: • The skimmer is still in its break-in period, which could last three days to one week. • The aquarium is not established and does not have enough dissolved organic compounds in the water. It may take one to three months or more depending on, among other factors, bio-load, feeding/maintenance habits and other types of filtration used. • Air intake is clogged with salt deposits. If you suspect this to be the case, run hot water through the air line and venturi intake to clean them. The air line may be changed periodically, if desired. • The pump and venturi intake may not be submerged to the proper level. The venturi intake should be submerged two to three inches. Evaporation and fresh water top-off can alter the water level enough to affect skimmer production.
