blueether Posted January 2, 2011 Report Share Posted January 2, 2011 Do fish like freon? My DIY refrigeration/chiller just decided to start blowing bubbles in my tank, and upon removal it was hissing at me :tears: I hope that just the fan will be enough cooling for my natives as I wont be around to keep an eye on them as I'm off to enjoy the summer sun on the east coast. Edit: offending cooler Quote Link to comment Share on other sites More sharing options...
Zev Posted January 2, 2011 Report Share Posted January 2, 2011 2008FR DuPont Page 7 Material Safety Data Sheet # Ecotoxicological Information Aquatic Toxicity: "FREON" 22 48 hour EC50 - Daphnia magna: 433 mg/L 96 hour LC50, Zebra fish: 777 mg/L Biodegradation: according to the results of test of biodegradability, this substance is not readily biodegradable. EC50 of a quantal dose response curve represents the concentration of a compound where 50% of the population exhibit a response after a specified exposure duration. LC50 value is the concentration of a material in air that will kill 50% of the test subjects Retrieved from: http://msds.dupont.com/msds/pdfs/EN/PEN ... 007210.pdf Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted January 2, 2011 Report Share Posted January 2, 2011 mg/litre is also ppm w/v but not sure if that is in the air or in solution. The solubility of freon is not given and I think freon has also now been replaced as a gas used in refrigeration. So "pass" I have no idea.

blueether Posted January 4, 2011 Author Report Share Posted January 4, 2011 On coming home from the beach the house was at over 30deg and the tank at 24deg. 5L of ice and a 30% water change and the temp is down to 21.7, should cool off much more tonight with the windows open and the fan still running.
