Rainbow Digital Temp. Alert Thermometers


I just got these - whatever Grahamling needs, he gets! He was too cold - so we got him a thermometer! And the tropis will need very warms tank, too! What on earth did we do last winter...?



The giant one is for the GF tank - it is great - wherever I look I can see the tank temperature - as an added bonus, I can see the room temperature! And, with high and low alert settings, I will know if the tank gets too cold right away - works in reverse in the summer! This stands upright or can be mounted on a wall (comes with brackets and screws - oh yeah - comes with a battery, too)!

The little thermometer comes with all the same features it just displays one at a time, a switch on the side flips from room temp. to tank/water temp. in an instant. It also has sticky pads so the thermometer can be mounted anywhere. (also comes with battery)!

I was carful not to place the probe too close to the heater - any advice on the best place to put it? mid-level inthe tank, bottom, or closer to the surface, away sorm air bubbler? I guess I will experiement while it is not too cold...

BTW - I was using the plain old traditional thermometer and it really works just fine! But, the numbers were very small and hard to read as often as I wanted to! I think they are very fine gadgets and I have used them elsewhere in the house - this is just a nice upgrade I am very pleased with that I thoguht worth mentioning. smile.gif

I am using digital thermometers too and they are very convenient :D 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! :D
