brine shrimp in 24 hrs

I tried a new technique yesterday to hatch bbs and was amazed to find most hatched after just 24 hrs(22 hrs to be exact) got the eggs (1tea spoon in 1 litre of water soaked for 1.30 hrs added 2 table spoons salt and aerated) so what did I do differently? well normally I use a heater/thermometer to keep the water warm but am trying to be eco friendly so I placed it instead above where my heat/uv lamp for my tortoises is (risk of electrocution i know but am not very safety conscious) as it get quite warm but never boiling and voila loads of bbs fast- - - could the uv have something to do with the fast hatching I wonder?

24 hours is a perfectly normal hatch time if the temperature is above 25 degrees celcius. In these days the temperature in front of the window (sunlight and warmth) is good enough. I don't think sunlight is necessary, though i could be wrong.

I always have a lot of hatchlings (hundreds of them), however only about 20 survive to adulthood, I have no idea why so little.

i am aware 24hrs is normal however the thermometer read 27 c as it did with the heater only i would say all of them seemed to hatch in 24hrs normally most half would hatch in this time and i would have to wait a while for the rest i think the uv bumped up the success rate
