As we all know the warm weather is coming! Make sure to keep an eye on your temps of the tanks, Recalibrate your digitals and have a second source to confirm temps.
My tank reached 85 today and it was only 73 in the house.
As always slowly cool the tank by adding some ice packs to the sump (or filter aera). Add cooler top off water.
Open canopys and add a fan to move the heat off the water surface and lights.
As always please feel free to add ANY ideas to this page that work on keeping tanks cool during the summer months without a 500$ chiller.
