Not for the novice

This new NEXX filter is the result of a large engineering effort.On the whole, it well thought out and well made. Unfortunatly the the designers knew the product too well. These units fit together only one way and the clues that that are not as bold as they should be. Note the extension unit does not the contain the biostars that are included with the basic filter. They are available from the retailer if you can find them.Warning tech support from API is hard to get to. I had the retailer give them a call -- that worked.
