Freezing temps.

Tank is in garage with front and back panels on stand with glass hood for dust reasons, has low watt heater set at 72* and woke up to 70* water temp. Pretty happy about that. Hope it conveys to moderate water temperatures in Summer and the chiller not running that often. If at all.
It‘s on an interior wall unlike others that were along an exterior wall facing South that outside weather had an effect on. Have a 200 watt heater on my shallow 10” deep 45-50 gallon pond due to keeping swordtails and platies in, temperature is 68. Pretty close to their minimum. It’s in a South East corner of the yard in shade all day long this time of year.

its fun to deal with summer or winter if you have tanks or sumps in the garage.
winter means heaters running more than we want
summer means chiller/ fans running more plus way more top off evap

past few nights ive been dealing with 30 degrees at night and system stays around 74-75
larger water volume helps in a lot of ways

have to love this pain in the @$$ hobby

Part of the fun/challenge is engineering the set up to work the way you want and having it work the way you want. Makes one less thing to deal with long term.
You mention evap. Yesterday at 7:30 AM I put a sticker where water level was in sump. Today at 3:24 PM it’s dropped 3/16 of an inch. We’ll see what it is next Wednesday at 7:30. Get me close to what size top off reservoir I’ll need.

yah the vap is the hardest.
last summer i went through 50 gals a week and i had less open top tank area.
this summer i think ill be close to 70 or more a week since i now have roughly 78 sq ft of open tank area
