Reply To: MY NEW FISHROOM..

The room is heated by a largish oil filled radiator, this works out cheaper than individual heaters in each tank. The oil filled radiator is good as when it hits the preset thermostat temp it stops using electric but the oil stays warm,when the oil temp drops it then resumes using electricity.
Top rack is stable at 82-84f, middle row at 79-80f and bottom tanks between 74-76f.
I have plenty of spare heaters incase any tanks need extra heating.
Filtration is by a large pond airpump and sponge bio filters, this was a cheap way of setting up but was prefered over a sump based system, that would of ment all tanks being drilled and connected to one large filter, the downside to this apart from the cost was that i would be forced to have the same water conditions in every single tank. This way i can run completly different water as and when required.
