The Precision Marine Mach 1 and Mach 2 protein skimmers are finally getting a release date and some tank ratings. According to PM, the Mach 1 will be suitable for aquariums up to 400-gallons, while its big brother can handle up to 700-gallons. As for a release date, the Mach line of skimmers will be available in a little more than a week. Despite their quickly approaching appearance, a few minor tweaks still seem to be taking place. For example, the Mach 1 in the photograph above the air intake for the Reeflo Dart needlewheel has been attached to the protein skimmer’s collection cup. There’s still no update on the price of these skimmers, but as with any updates, we’ll try to get more details.
