Tom, I think this depends a lot on incoming water properties. In SF
with very clean water, I need to clean my disk about every five
years. But I have customers with very hard water that seem to
precipitate CaCO3 on the disk. And some folks seem to grow algae on
the disk, my guess is they have a very acid-tolerant strain of algae
that I do not have. So I recommend that those without mega-hard
water try a small disk diffusor, such as the Eheim.
