Rainbow Digital Temp. Alert Thermometers

Wow, thats a great idea!! I always have trouble reading those TINY aquarium thermometers. Thanks for posting!

I am using digital thermometers too and they are very convenient I have attached mine to the opposite side of where the heater is as that is what was in the instructions.I have my heater on the left side and the thermometer on the right side of the tank

I don't have any heaters (bought some but not installed - never used before).

I think it is DEF a good idea to keep the thermometer probe away from the heater but I was wondering if placing it too close to the air stone would decrease the temp. reading or too close to to the filter intake would increase the temp. reading... OR if placing the probe low in a deep tank would overheat the tank because the temp. would be read at its lowest - yet placing the probe too high (i.e. near the light) would underheat the tank becasue the temp. would be read at its maximum?

So, I guess the best placement is away from the heater, not too near the air stone, not too near the filter intake, not too deep (esp. for those with tropical tanks), and not too near the surface (esp. depending on how much/how many hours the ligh tis on) so that an average and accuate temp. can be taken so as to adjust the heater... particularly if a thermostat is being used!

I will experiment a bit but I guess the mid-level probe will reveal the average temperature best. I will compare beteween tanks, once I use the heaters, and check back in!

I have one on my Dede tank Shes been sick for a long time and its great, All I have to do is look over and see what temp shes at.

I also have one on the salt water tank and I tell you its a life saver for that tank

I have a rainbow too and I love it. Got it at a great price, new off ebay.
