I'm setting up a plastic tub to throw in some rock to cure for a few months.
I know I need a heater and a powerhead.
However, I'm curious how steady I need the temperature. The container is quite large, and I'd need to go out and buy a 500w heater to reasonably keep it steady. Also, how much flow would I truly need?
Last but not least- how often do you change out the water in those months to get rid of the nitrates? Or is it a waste?
TIA
