Hello. I have an opinion question regarding evaporation. I apologize for the long post, but I feel like a little background is needed. I live in the Dallas area, and we are having a crippling experience because of this winter storm. I have been one of the lucky few to have had electricity through all of this, but now our cities are running low on water. Many places do not have water and some are on severe restrictions. My city has been asked to severely limit water use. So here's the question, my open- top aquarium has been losing about 2.5+ gallons of water per day since this started. I had an adequate amount of top off water to get me through the past week, but I am running low. In an effort to conserve water for those that have none--and because of the freezing temps--I do not want to/can't use my RO/DI unit. I have about 6 gallons left. Should I cover the aquarium to reduce evaporation, and if so, how much do you think that will affect the water parameters and the livestock? Is there a better option? I just upgraded from a 40gal to 75+ sump about 2-3 months ago, so although the aquarium has been quite stable and is doing well, I believe it is probably in a quite fragile state given the timing of cycling, etc. Any advice is appreciated.
