Guide Review
The Precision Marine CV Series of in-sump designed skimmers are well designed and built skimmers that are rather compact and ultra efficient. Combining venturi skimming, slower controlled flow of aquarium water throughout the reaction column, against the rising air bubbles to maximize water contact time, an attribute of the air-powered skimmer, these units produce an abundant quantity and consistent fine mist of air, without the need for an air pump or air stones.
