1dF wouldn't do anything to the fish, or the heater.JEAE21;1180138;1180138 said:When you say directly on the heater, are we talking about outside of the tank?
My heater is on the middle of the tank and I usually pour in warmer water all over the tank. but today I had water hat was 1F colder than the tank..I poured it on the right corner of the tank..so do you think my heater is safe?
so are the stealth heaters not gonna break even if I pour colder water in the tank? Would the rush of the water getting poured in, reach the heater?
