Tank ID please

Nitrate is at 1.2 ppm
Phosphate is at 0.06 ppm
The corals have been growing like crazy lately, I did a 10 gallon water change Sunday
Not sure if I should cut back on the skimmer for a week so the nutrients can rise back up. Any help is greatly appreciated, I went to California for 5 days and came back to this stuff on the sand and tank walls.

Your phosphate is fine. Consider dosing ammonia.

PS: Not sure why, but I can’t see your video. Take a full tank picture with white light.

Ill have my partner dose the tank while I'm gone, how many drops should I put in? I have three bottles of Dr Tim's ammonia left over. I can get you a picture tomorrow!

In 55G macro algae growout tank, I add 10ml twice each day during lighting cycle. On 25 year mature 75G display, I add 5 ml each day.

PS: On 55G grow out tank, I had water tested after dosing 20ml of ammonia every day and 5ml of liquid kelp concentrate every other day and nitrate showed zero.
