Where To Put Sensor For Thermometer

[howmany]

I got a new thermometer for my aquarium today. (lost all my fish to a new heater that over heated)

I replaced the heater that cooked my fish with a new one and different kind & maker. I have been using a stick on strip thermometer that was a cheapy from Walmart. I figured I needed a better one.

I got a new digital thermometer today that the sensor goes inside the tank and the readout is placed outside the tank.

My old strip thermometer was put on the front of my tank, on the right hand side (same side as heater. Filter is on left of tank, with bubble stone in right rear corner of tank)about mid way up the tank.

Where would be the best place to put the sensor of the new digital thermometer for the most true and best reading?

I put it in middle of the glass of the tank. Not to the left, nor the right, not up at the top, nor at the bottom. I tried to get it as close to the very middle of tank as possible. It is on the front glass, not on any sides of the tank.

I have a 30 long, freshwater with platies, longfin black skirt tetras, black neon tetras. And of course a few cory cats and a couple small plecos.

I would position the sensor right over your bubbles. That is the spot in the tank that is going to have the best water circulation.

Would that give me the best accurate temp of the water? I have the heater over the bubbles so it gets plenty of good circulation. I thought you weren't supposed to put the thermometer that close to the heater.

I put mine on the opposite end of the tank to my heater to check for flow circulation.

If you have the heater in the bubbles, try putting the sensor below your bubble wand. That way you expose it to a well mixed and moving water flow while not getting any of the heat right off the heater.

I have 2 thermometers in my tank. One either end of the tank. Also use I use external heater so the water should be even throughout the tank.
