    Aquarium Products Reviews
    Just a head's up, Cobalt Aquatics is kinda new on the block, so I gave them a go with trying their EasyTherm 75 watt heater. I purchased it October 7th 2014, and it died last week, first spiking a high temp in the tank, then dying completely. However, it has only taken me 3 days to get a RMA...

  6. Do you find you have to adjust your heaters?

    Aquarium Products Reviews
    I have two Aqueon, 200 wt. heaters in my 55 gallon tank. They are very reliable, and I love them, EXCEPT when the weather changes. If it's pretty warm, I have to adjust the dials to around 72 on both heaters to keep the tank around 78-80. In winter, I keep the house around 62 degrees at night...

    Freshwater Aquarium Equipment
    Do any of you have the same problem I have with the tank temperature? My house gets cool in winter (often down to 60F) so I have to turn up my heaters quite a bit to keep the tanks around 78-80. When its warmer, I have to turn the heaters down again or the tanks will get too warm. Sometimes...
  10. My advice reguarding Hydor Heaters

    Freshwater Aquarium Equipment
    Never buy a Hydor heater. They are garbage! Mine, after 5 of 6 months of use just suddenly stopped working for no reason. I went online and researched the problem and it turns out I got lucky. Apparently Hydor is infamous of getting 'stuck' and frying people's fish! The sensor breaks and...

  13. heater for a small tank

    Freshwater Aquarium Equipment
    I have a tiny 2.5 gallon tank. I have a small heater by Tetra that I buried under the gravel. It works fine, but there is no way of regulating the temperature. So if I leave it on all the time, my water goes up to 85. It's a pain having to remember to turn it on at night when the house cools...
  14. Heating aquariums - thermostat settings and temperature

    Beginner Freshwater Aquarium
    I've ended up with three small (20L) betta tanks added to my fish menagerie. It's autumn and starting to get cool at night so I've been studying the temperature settings to ensure that everybody's warm enough. I have 25W Aqua One heaters in the tanks. The box said that that size was suitable...
  15. Heater Suction Cups - Advice

    Beginner Freshwater Aquarium
    I've been having issues getting the suction cups to stay stuck to the glass. They are for my 150W Heater. I decided to give up on them and ordered magnetic holders online. I haven't received them yet but was wondering if anyone here has tried them. I'm mostly worried about the magnets...
