    I would like to get an idea of the evaporation rate you guys have..

    At this stage it looks like I'm having about 5-8 litres a day.

    Seems that when I have a lot of surface movement, the evaporation rate goes up.

    I also had 4 10cm fans runnning in the Top to keep the lid and light areas dry. I now have 2running, and is considering having only 1 running.

    How many litres a day/week do you guys have to top up?

    Biggest questions

    Are you running a chiller?

    Are you running a fan?

    What lights do you have?

    How close to the water are they? and do they have fans in them?

    Do you have a light in your sump?

    Is your sump open or closed?

    All these things impact the evaporation rate.

    This is alarming...i do about +/- 5ltrs a day...when we hit the hot summer days we need to re-look at this..and keeping the water cooler...topping up more..

    Your evaporation is normal. I add 4.5 litres per day at the moment!
    My R.O unit barely stays ahead:(
