Anybody know a way to reduce condensation on glass canopy?

[vfc]

I have glass canopies on all my tanks. The problem I am trying to solve is how to reduce/eliminate the condensation that forms under the canopy.

My water is very hard and I end up with so much calcium build up that it significantly reduces the light passing through it. It's a PITA to remove.

I have the lids propped up about 1/2", but that doesn't help much.

Any ideas?

not much you can do about that. the warm moist air above the water condenses on the cooler glass.

the only think I can think of would be to get a reverse osmosis unit and perhaps use 1/2 RO and 1/2 tap water for your water changes which would cut down on the hardness.

Make the room(or just the glass) warmer than the tank water?

use a small computer fan to blow a constant flow of air through

I agree with this, but how you would make the glass warmer I have no idea.

Also more ventilation under the glass would help... again how you would do this I have no idea

The tanks are in the basement. Some in the unfinished (unheated) side; so raising the room temp would be expensive.

I like the idea of a small fan. I have plenty of computer fans from all the PCs I have made over the years.

The downside of using fans is more evaporation from your tanks.

I've been thinking about the same thing. I wonder how polishing it up with Carnuba Wax would work. I'm not entirely sure if Carnuba Wax is fish-safe though.

worm the glass with a heating pad fore a dog or snake.

If your lids fit so tight that its a pain to take them off & scrub them, why not just get a mag-float for the glass tops?
