Hello fellow reefers i have a serious question

[mikeclarke]

I have a Costco.ca dehumidifier in my sump/furnace room that pumps the water out to a drain. It doesn't smell. I have an ATO on the salt mixing tank and for the make up water tank (a 5 gallon pail). So far it's been good but I've only had the 100+50 tank going since August. Before that I had a 20gal tank that had a covered canopy so I never had issues. My 100dt has no cover but I've noticed that I am getting more condensation on the windows as it has got colder outside.
