Tank in front of window?

[KrisReef]

Yes, tank will back up to the window and blinds will most likely remain closed at all times.

I support placing a tank in front of a darkened window if the house lacks a wall for the tank to sit on.

Care to keep the curtain unsplashed is the only thing I would be concerned with

I also live in Florida (South) and my peninsula is sandwiched between a large window and my large sliding glass doors. It receives a lot of natural light, especially in the AM. I don't think you should choose to do it if it can be avoided but its not a dealbreaker. Your typical reasons for not wanting to:

(1) Algae: Yes, the areas of my tank receiving natural light have more algae. You have to clean the glass more often for sure. But the corals receiving natural light are also thriving? I don't think its a big deal. I would be willing to bet tanks that have unmanageable algae issues would have had it with or without the ambient lighting.

(2) Temperature: Not as much of an issue in Florida. Now I see you are up in the Jacksonville area, so maybe heating is something to consider. Winter lows in the 40's vs lows in the 60's where I live. However, depends also on your windows. Mine are the hurricane rated impact windows. They don't transfer a lot of UV or temperature, hot or cold. Depending on your home, in the winter your heater may have to work a little harder but most the time it will be negligible. In the Summer, you have A/C. Unlike some people in other regions who do not and have to manage heat.

Let there be light! The sun is ensuring everything gets the proper spectrum lol it’s only for about 1 hour each day

I get ~ 30 mins a day of direct morning sunlight on my reef tank, through my fish room’s UV laminated multi-wall polycarbonate door windows!

My lights turn on at 8:30am, but every leather coral is showing significant polyp extension 60-90mins before… they seem to enjoy it!

The exposed sump wall facing the doors does have a consistent algae biofilm, but that will be mitigated with a sheet of HIPS plastic during the next remodel!

Continuing the journey of setting up my IM 100 mixed reef tank. Can I place the tank directly in front of a window or will that create problems? Additional info, located in sunny FL, window has blinds, and back of tank is blacked out.

Are you nuts?????
Too much sun
Too much heat
Too much trouble !!!!

The horror stories I've read, you'd be fine if the blinds stay closed, .... I think.
