50W, 75W, 100W? Also what are the reliable brands?

I have a 24g nano and I use the walmart brand sub heater. I have a visatherm in another tank and I sadly perfer the walmart brand. Be careful when adding the heater, the small nano tanks run hot anyway about 80F when the lights are on.

Will a glass tank stay cooler than an acrylic?

i have a 14g bio aswell i use visi-therm 50 watt. its like 20 dollers and its plastic itworks i guess lol

Thanks EC. The visi-therm 50W says its good up 10 gallons. I assume you are having no problems.

np but just not the normal visi-therm i use the "stealth" visi-therm wich meens 50w is good up to 15 gallons (lil more powerful ) =]

Ahh thanks EC! :up:

no lol glad to help =]

I only needed a 25w Hydor Theo on my tank to maintain. I have to admit though, I did not like having to trust the dial on the top of the heater. More often than not, hobby heaters are very innacurate at hitting what they are set at.
