I sent my minidos for service today, the piston is finaly worn...Dosmatic have been bought out by Hydro Corp which also owns chemilizer. I just order a chemilizer since the service takes about 2 sweeks and I don't feel tlike doing water changes

Also, I've been dripping about 20 gallons per hour between 540, and the fish room. I dripped 10 hours per day.
Thanks for the update flemenco-t, any updates on the longevity between the need for a new diaphragm? Hope someone back in '08 can answer this, looking into doing a drip system on my 240G as well. Want to keep that water fresh for the rays and fish.
