i have a salt water tank water cooler. if i were to fill a 150 gallon tank with 5 inches of water, then have it so that the plants are sitting on top of a divider supported by pots, then use the cooler at night, would it have the same effect as using a aquarium heater to heat up the tank? the cooler can easily freeze water if given time, and can be ajusted to different power levels.
would this work?
thanks in advanced,
