Dealing with a case of Ick so I went to increase my water temperature, but found my old heater (150W) would not get the water warmer than 79 F.
So I replaced it with an Aqueon (150W) turned it on to 85 F and waited for 24 hours. It too would not get the water to the desired 85 F even after turing it to the max of 88 F.
So I returned it and exchanged it for the Aqeuon PRO (150W), installed it last night and after performing a 30% water change set the temperature at 85 F and this morning my water is 81 F.
My water was 79 F after completing the water change and I expected to see mid 80's this morning.
The RED light on the heater is on which seems to indicate the heater is still in the heat mode and the temperature setting has not yet been reached.
I have TWO thermometers showing the same readings.
Is it possible I have another defective heater?
Are the heater dial's this far off from actuality?
How long should it take my 29 gallon FW planted tank to reach the desired temperature?
Am I not being patient enough?
I would prefer to try and iradicate the Ick through heat, but I'm getting concerned that I need to go with med's as I can't seem to get my water to the correct temperature.
Thanks for your feedback and suggestions.
