That is what I wanted to hear, it makes sense that the condensation shouldn't have much of an effect now that I think of it. It's just water like the rest of the tank.

Thanks, that was a good

Like others have said, only if there was a lot of mineral buildup that might happen.

Great!! Hoppy knows his stuff.

Since most people's algae issues are because of light, it makes sense to try to raise the fixture instead of buying a new one.

I raise lights to reduce the value balancing new tanks rather than changing fixtures.
Thanks for the input, it's all about balance and sometimes that requires raising the light, especially for low tech. Thanks, hopefully this thread will help some other people.
