I'm already planting my veggie seedlings in my greenhouse today with my daughter Felicia. Also moved my citrus tree collection from the front of my home to the greenhouse since the long range forecast shows no more nights below freezing (maybe -1C outside but it should stay above freezing inside the greenhouse.

BTW, back on topic, my 165g with 90% coverage w glass tops and open top 90g wide sump loses about 5g every 3-4 days. My new system with a 30" cube and 2' cube (both with full glass tops) and open 2' x 2' sump loses about 1 gpd. Its the main reason I use glass tops, even if they can be a bit of a pain when working inside the tank.

I was losing a pile of water from my tank 550 gallons water opened top with lots of surface agitation, covered the sump up and it stopped a pile, kinda nuts on how fast you get water droplets forming in the lid.

Yikes! I have been really curious as to how much those big open tops evaporate.
I shall consider myself very lucky to be adding a mere 2 liters every 3rd or 4th day on my 95% closed top 33gl-WOW!
