Visi-therm stealth

my visi-therm is always having these small bubbles grow on it, i tried wiping the bubbles off but a few hours later its back.
 
LMAO!
 
lol, well it would be nice finding out whats inside..... although you end up rendering it useless.....
 
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:

just because it costs more doesnt make them better.

when i was setting up my tank everone was saying use jebo heaters. i found visi therm heaters and really liked them. never bought another brand before.
 
does anyone have an explanation for the bubbles?

I did'nt say they were better, but they seem to be accurate, I was just wondering why no one seem's to be intrested in them,maybe because they cost more....
 
I got the visi-therm stealth 100 watt heater for my 20 gallon tank today.


Excellent heaters! It's what I use in my tanks.
