@@stevezodiac491 yes - so the dryer air is pumped in through one hole via the aquarium air pump tube and the moist air/condensation is driven out through the other open hole. The window is still clear 3 weeks on - and there has been quite a lot of rain.
What is the make of the pump
@@carolejenkin454 the pump is a generic one QZ - HQ601. Search eBay (uk source) for “Silent Aquarium Air Pump Single” - £8.45 inc p&p!
You didn't make it quite clear, did you remove both bungs and put the pump hose into one of the open holes ?
