heater in sump...

[76dragon]

I usuall have 2 300 Watt heaters on big tanks.

[mahoro]

how long is the 200w heater? same size as the 150?

[myjohnson]

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.

[mahoro]

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.

i got a jager heater 150w on my 55 for my turtle in the winter, works great, isn't 200 w only rated for like 75 - 100?

Total water volume to start...


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

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.

[mahoro]

plastic on sump? oh, i should of stated the sump will be made from either a 20L or a 29g tank...

[Darbex]

+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.

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

[mahoro]

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?
