The Opae ula shrimp Forum and online store

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".
and off at 2am.

No kidding, we need a chiller for us humans!

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.

Opae really like it warm Mine start to be more active now that the water has 26 C from ca. 23 C.

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.

Well... mine rose to 28 today I am not worried about Opae Ula at all. But the snails might cook

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.

I'm running a small tank in a down stairs room in my house and its sat at around 20 - 21deg C which is pretty good.. no heater needed but we are due a heat wave this weekend so it will be interesting to see how that goes.

Any babies in there?
