What temp do you keep your nute tank at? I've read everything from 20 to 24c but that's quite a range....and want to set the tank heater up to keep a constant temp.

between 18-21, remember to raise the temp from cold to warm, not from warm to cold(kills the o2 in the water)

Thanks man...in this weather I don't think I need to use it at all....will save it until the winter or maybe winter nights and go with room temp until then.

do you have a water temp meter?
