Not sure that would be the best option. A slow decrease in temp would be best. To much to soon would most likely cause issues.Rather than fool around with ice cubes I would have scooped out a good portion of that hot water with a bucket and replaced it with cooler water.
Well,it was when I was faced with that problem,obviously the temperature can't be changed abruptly.Not sure that would be the best option. A slow decrease in temp would be best. To much to soon would most likely cause issues.
300 watt, 75gallon tankJust out of curiosity, how many watts is the heater and what size is the tank? Just a suggestion, but one thing that works for me to keep heaters working well for a long time is, keep the dial end out of the water. I know they're all called "submersible" these days, but every one of them will eventually get water in them if you keep the dial end under water.
300 watt Marina. it was cheap, ~$15. i have had it for a couple of years, just glad i caught it when i did.What heater is this?
