So....to summarize In-Tank and Hang-On designs:
- Co-Currents are great for smaller systems up to about 29 gallons or so.
- Counter-Current models are great for 30 to 75 gallons, both reef and fish-specific.
- Hang-On's address larger setups and are more numerous in design and flexibility, usually being recommended for tanks from 55 gallons and up.
- Air Driven models are less efficient and require a separate air pump and frequent replacing of the diffuser.
- Collection cup drain hoses are a must!
- Surface agitation is required for non-surface feeding skimmers.
In Part 3 I go into detail about Installation Options for Co-Current, Counter-Current, Free Standing and In-Sump Skimmer set ups.
Happy Skimming,
