From what I have read it will hold the settings for a short while. But when the power goes out for a long time everything is lost even the clock settings. AS nice a unit it is it is extremely difficult to program.

Yikes! Roasting corals sucks - it's a long road to recovery.

I just re-started NaNO3 dosing too, but I'm adding KH2PO4 as well since I have neither measurable in my tank. Makes sure you don't bottom out PO4.

I am hopeful the corals will be OK. The only one I may loose is a mystic sunset monti. Not the end of the world as I am battling the early stages of monti nudibranchs Likely stress of the water changes combined with stress from the lighting combined with the nudibranchs.

I am trying to get 2ppm NO3 and .03 ppm PO4. As of yesterday I was at .003 ppm Phosphate 1/10th of where I want to be.

MY tank is sucking up the phosphate and the NO3 right now.

Where do you get the Potassium phosphate? What rate are you dosing?

I got it from a friend, pretty sure he got it from "The Plant Guy". Google it, he's Canadian. Not allowed to post a link.

I'm adding 0.02 ppm per day right now to see what happens. So far only dosed twice.

Great let me know how it goes with the phosphate. I tested mine last night and I had .02ppm phosphate. I am happy with that for now.

Apparently the too much light issue is worse then I thought. About half of my acros are showing stress, I have tip dieback on my pearlberry and red planet. My aussie toxic yellow large colony has been hit hard I am not sure if it will survive, my highlighter is not looking too good.

I am wondering if the intense light (week) combined with the extremely low phosphates has caused the problem. I was running the GFO for several days with no phosphates and bright lights.

I knew the power outage affected the timer but I didn't think it would have affected the program.

I have covered my tank with a layer of transparent tracing paper to reduce the light to the corals, once they are responding well opening their polyps I will slowly remove the tracing paper.

You should see if your alk is fluctuating...I would start with that first then worry about your lights. You should also stop the GFO for a week also.
