New 73 gallon tank setup

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.

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.

Alk is at 9.5dkh. It went up from about 8.5 naturally when I brought my nitrates up. I have added very little buffer in several weeks

I haven't been using GFO since April 13, since my phosphates zeroed out.

I am currently checking nitrates, phosphates daily, alkalinity every other day and calcium twice a week.

My calcium requirements have more then tripled.

I checked everything last night

Alk-9.8dkh
Calcium- 450
Nitrates -1.5ppm
Phosphates at .006ppm or 2 ppb phosphorus on hanna ULR

If I were to guess without looking at your tank, I would think po4 might have been striped way too fast. I think you'll need to let it runs its course and don't do anything drastic, bump up the feeding a bit for sps corals using oyster feast or sps food like vitilas or any filter feeding food along that line. Wait a few days and see how the corals react.
