Moisture on windows

[littlesilvermax]

I have a HVR and they are great! When you have a reef tank always get one way bigger then what they recommend. Mine is twice as big as recommended (190cfm vs 90 cfm) and I wish it was bigger yet.

A low to mid efficient furnace will actually make the air in your house dryer due to the chimney forcing moisture out. A high efficient furnace will generally result in a house with a higher moisture content. New energy efficient windows also keep the moisture in.

For best results you want to use a min of 7 inch diameter tin ducting to and from the unit. Besides having the regular inlets in the bathroom and the kitchen hook a large one over the tank if you can. Of course this is easier to do when the house is being built rather then after the fact.
