Question

Answer 1

you will have to get a tank thermometer, then gradually turn up the heater a Little at a time leaving it for about an hour between each raise in temperature checking the thermometer to see if you need to raise the temperature again

Answer 2

Just move it up a little.not all the way.Try buying one of those stick on thermometers that stick to the outside glass. They only cost about 2 dollars. Or, if you really know what your doing put an oral baby thermometer in the tank,,but hold it there for three minutes and compare what the readings are.

Answer 3

Ihave no idea what you r talkin about

Answer 4

It depends on your fish but since im assuming they are tropicals 100 watt is not enough for a 29 gallon tank the minumum is about 150-175 watt so go ahead and put the heater as high as you can. if you just need the water to go 3-4 degrees celcius then put it max if you need it fareignheit leave it.
