One week to cycle ?!

Man ... I feel so ripped off.

Anyhow, I've taken mine offline for now. Will tinker around tomorrow or the next day time permitting .. I agree about the sulfur amounts -- seems to me if it's too small it should just not be able to pull down the tank nitrates as quickly -- but should still cycle and still output zero. At the very least I'm going to swap the pump leads to reverse the flow, and if the recirc pump isn't enough to draw sump water then I'm going to fashion some kind of gravity feed and see how ridiculously slow I can make the flowthrough.

Don't know what to say about the Midwest units using a smaller pump. All I can say is I gave it a month .. and it wasn't cycled so I know something's not right. All I can do is guess at what ... I wish I had more answers.
