How to choose the hang-on or in tank skimmer

Obviouslywe all know that not all skimmers are right for all systems.

One area of concern is the INABILITY of In-Tank and Hang-On's to skim the oil and other dissolved organics that float at the surface. By having their pumps below the waterline, these harmful accumulations are left unattended. A simple solution to this is to place a small powerhead just below the surface. This creates turbulence and keeps the accumulations more in solution, Thereby Allowing the pump to deliver them to the skimmer for processing.


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.

One last thought regarding adding to Hang-On Skimmer AFTER you have gotten your established aquarium, plan ahead and make sure that there is at least 6 inches of free space between the rear of the tank and your wall! Nothing is more frustrating than to buy a skimmer (or any other device Hang-On) only to find that there is not any room to mount it! Been there, done that.
Any other comments are welcome!!!
