hello. It's time for me to buy a heater!
I'm a college student on a budget (even though I don't mind spoiling my
Timmy now and again). I see from the site that The Marineland Visi-Therm Stealth Submersible Aquarium Heater (100 W is $35) is very popular. I have a RES in an approx 20 gal tank. What other heaters would you all recommned? How important is having the heater fully submerisble?
Please give me your opinion of the following:
Visi-Therm Deluxe Aquarium Heater (100 W @ $25)
EHEIM Jager Aquarium Heater (100 W @ $22)
THEO UL Aquarium Heaters from Hydor (shatter-proof glass, 300 W @ $30)
