Bill - I bought a pair of Algae-X® units at the Lauderdale show last Oct for my
Cummins 6BTA 250's and put them in over the winter. I have them in my Bertram 31. Have about 150 hours on them, and drained the Racors last Sunday for the first time since installing. NOTHING, I mean nothing, in the Racors. Normally I would get an inch of crud out of each filter after about 50 hours, but NOTHING. I could never get 100 hours out of a 30 micron Racor 500 cartridge before, and now I'm up to 150 and counting. Plus, the smoke is greatly reduced, the exhaust smells cleaner, and - here's the best of all- fuel economy is up over 10%. Magic? You tell me. A trip I made last November prior to installing the units, yes with a dirty bottom and one slightly dinged wheel, burned 126 gallons. Two weeks ago made the same trip, plus another hour of running, yes, this time with a clean bottom and true wheels, burned 100.4 gallons. I am a true believer now. Thanks for talking me into buying them.
