I am very pleasantly suprised so far. Inside temperature right now is 73F. My tank for the past 2 weeks has been in the range of 78-82F with running the actinics for 12 hours a day and hallide for 10 hours.

I notice the forecast is for temps up to 35F for the next week and our rancher is south facing. I have an air conditioner that I can temporarily install in the window when necessary so this is going to be a major test.

I replaced the fan that came with the tank (it was way too noisy) with an Ice Caps variable speed fan. It has a temp probe that is installed between the water surface and the lighting unit. It is set to automatically come on the lowest setting at the same time that the hallide starts. The fan speed steps up as the air temperature increases. This fan is also super quiet which is a bonus.

I do have a 2nd fan that I received from CadLights. It is nearly silent although it is either on or off.

So next week I will shorten the time that the hallide is on and install the additional fan. In additon I have had a JBL top off setup so with all of this extra evaporation due to the fans, the salinity of the tank will stay relatively constant.

Next week will certainly be a big test.
