Hello,

a bit of advice on what temp to set my heater on for my shrimps. I have yellows, blues, cherry, bloody Mary's all mixed in. I have read that you don't need a heat, you need cold water, then you need a heater set at 25 degree's, so I'm not sure. I just turned mine up today to 27 degrees due to it getting cold but may do more harm than good.

Regards

Byrnesy
