I had this problem this year and was looking at the hrv route but decided that it's only for a few months that this is a problem. Pick yourself up a dehumidifier from crappy tire they are always on sale right now and put it next to the tank and it will solve most of your problems. When I first started I was emptying every day but after about three weeks it's every other day. Cheapest fix for what you need. Hope this helps.
