  • heater in sump...

    i've seen many people put heater into their sump, now do you put the heater that is rated for the sump or the tank it self? or total water volume?

    I would go with one that's rated for the tank.

      Total water volume.

      What are the facts? Again and again and again--what are the facts? Shun wishful thinking, ignore devine revelation, forget what "the stars foretell", avoid opinion, care not what the neighbors think, never mind the unguessable "verdict of history"--what are the facts, and to how many decimal places? You pilot always into an unknown future; facts are your only clue.

            I use a Stealth visitherm 200w in my sump on my 180g tank. Holds the temp VERY well... less than 1 degree change.. now please remember I keep my house at 71-72 degree's so yes it does get used all the time.

              +2 on the water volume. I am unsure if the plastic on a sump is built for the heat or not so you may want to make sure the heater glass isnt touching the sides directly. Use the suction cups.

                  One of my heaters does not have suction cups and it lies down on the acrylic... but I am going to agree with Darbex... put the heater in using the suction cups.. makes it more stable.

                    Total water volume to start...


                    If it's kept in a colder place then you might need more... vice versa.

                        yes 200w is rated for about 75g. However, other things heat up the water: lights, filters, and powerheads. It's also important what the room temp is.
