Key Features to Look For
When you’re shopping for a hob protein skimmer, keep these important features in mind:
- Size and Capacity: Skimmers are rated for specific tank sizes. Make sure the skimmer you choose is appropriate for your aquarium’s volume. A skimmer that’s too small won’t be effective, and one that’s too large might be overkill.
