I have also noticed conflicting ads on the microns of a Dolphin filter bag. Aquabot makes a real point about marketing their 2 micron filter bag. If Aquabot never brought a numerical rating to their marketign campaign, no one would have ever thought to ask, and they would just look to see if the pool was clean. Anybody who asks Dolphin about microns is going to put them on the defensive. It would be like calling up Aquabot and asking them if they used a drive belt.
