SeaSide Aquatics has been blazing a trail paved with new products in recent months, the newest of which being another noteworthy hang on protein skimmer. The ES1 Hang-On protein skimmer shares some similarities with the JNS-built DeepWater Aquatics hang-on protein skimmer.
A Shark pump powers the entire assembly of the ES1 hang on protein skimmer, but the field of conical nozzles and diffuser plate is replaced by a more conventional mixing chamber and basic diffuser. A standard issue skimmer cup does stick up out of the body of the SeaSide Aquatics ES1, but overall this model looks like a slightly beefier option as far as hang on skimmers go.
The entire body of the ES1 hang on is 16 by 4 by 7 inches in volume with just the intake pipe and spillway protruding from the body into the tank. SeaSide Aquatics rates their $199 ES1 hang on skimmer for tanks between 75 and 100 gallons but that value will depend on your real world stocking level. [SeaSide Aquatics]
