I got the visi-therm stealth 100 watt heater for my 20 gallon tank today. I have noticed the difference immediatly, with the all-glass heater i used to have the temp would go up and down 1-2 degrees all the time, it would either be like 83 degrees in the morning, and 80 degrees at night, never stable. But with the stealth, it is at a constant 81 all day. Thanks everyone for the suggestion, im sure me and my fish will like it a lot. Now i dont need to worry about a heater over-heating and cooking my fish :)
 
I myself have a Visi-Therm Stealth heater, it is possibly the greatest heater I have ever bought for an aquarium. You never have to worry about it breaking and hurting your fish. I would never buy any other heater ever again. Definitely recommend it!
 
Glad you are happy with; sure love all of mine.
 
musho, I notice you have danios in that tank. 81* Tis a bit high for them.
 
Just wondering why no one mentions Rena Cal Top Light Excel heaters, is it because they cost more ? The 300 watt we have regulates to a 1/2 of a degree. useing 2 digital therms.on each end, constant temp is between 77.5 and 78 under controled conditions....Thank's....:idea:

yeah i got danios but i also have bolivian rams, the danios are fine in this temp, no behavior change from when i had them in 74 degrees. But higher than 81 they start to act different and lower than 81 the rams act different. So 81 is middle ground.

Also another great thing about the heater is that i set it at 81 degrees.... and its at 81 degrees, if i set the all-glass at 81 degrees it would be at like 90 degrees. Only con i can think of is that there is no light that shows you when its on :(
 
The no light is a plus for some of us. More than one story over the years of the bigger cichlids attacking heaters when the light came on and off.
 
well its a win or a loss for everyone :)
