The weather here is starting to heat up. Today's 83 degrees. A bit too high for my freshwater Neocaridina & Caridina shrimp. I decided to use my CoolWorks IceProbe to lower the temps. I bought these used off of eBay. I would idealy like to be around 74 degrees but I think it will only lower it 3-4 degrees in a 10 gallon tank. I tried this on my 5 gallon tank last year and it worked great. That was in the winter. I plan to turn the lights on at 6pm. I know the opae can take the heat but the FW shrimps need to be in the 70's. I still would prefer my opae to be at or around 74 degrees.

Now the manufacturer states:
"A single IceProbe can cool 10 gallons of water 6-8F below ambient air temperature in a standard aquarium. Multiple IceProbes can be used in a single aquarium to achieve higher temperature differentials".

Yeah it weather ended up at 93 but I was able to keep the tanks with the chiller at 76 and the rest were around 80.

I would prefer mine to be at 23c/73 degrees. That's about where mine has been. Now the tanks are at about 27c/81 degrees now. The two that have the Iceprobe cooler are at 23c/73 degrees which is perfect. It took around 24hrs to bring the temps down.

Overall I never worry about the adualt opae. I've had an outside tank get up to 96 degress without any deaths. Granted it was only for a day. I've never had any issues with adults in any of my tanks. The bebies well that's a different story.
