Protein SKimmers and air pumps

[APEX_AIMZ]

Can u have a protein skimmer without a sump and do have to have an air pump in a reef tank

 

[hkgar]

Yes to the first Q. There are external skimmers and HOB style also. No do not need an air pump but have enough circulation to have some surface agitation

Exactly what hkgar said. You would actually not want to use an air-pump. It would cause massive salt creep.
