Some UK retailers have been receiving Fauna Marin’s blue line protein skimmers in stock these past weeks. There are 3 models in total, each with the option of either having mesh wheel or needle wheel impellers. Besides all that pricing has also been leaked out and it isn’t pretty for the US. Pricing for the Blue line protein skimmer 3 is right at Â£799.99 or about $1,590 million US dollars. Interesting too is the mesh type impeller is an additional Â£50 ($99.50). Whaa?
