is it an all in one like a biocube or JBJ unit?Sorry, 24 gallon
If so then I have heard good things on the Tunze units, but personally I would go with water changes - those skimmers are so small and the collection cups are so small you will need to change it out every day
If you have a sump then skimmer choices become much more vast.
Do you have one?
