Evaporation

Like yesterday here it was 74 outside and 17% relative humidity outside and I opened all the window and doors and The water level went down fast the house was at 26% humidity and with 3 400 M/H's and some serious fans I bet It evaporated over 7 gallons all day . Today its cooler and semi rainy and it will be far far less today . Thats the good thing about an AutoTop Off it keeps the systems salinity level and far more consistent and steady..

 

I have MH's over my 90 and use a fan to push the warm air out from under the light. I'm thinking I was topping off 1-2 gallons a day depending on the day as stated above. All I know is it was enough water to drive me to purchase an ATO which made my life a lot easier!

 

ok so ato sounds really good i know what it is but how and where does it work?

 

You dont have to add salt when you add water that is just being replaced due to condensation Right?

 

No you don't have to add salt just fresh water.

This is the ATO I use:
