CORALS NOT OPENING HELP!

[yayaaa]

Advice on lighting please. See above

Forget PH. sorry but that’s a waste of time.
Your phosphate is Ok if that number stays solid and doesn’t increase.
Your Alk is fine provided this is what your system has been running at.
You could bring nitrate up from 0 to say 5ppm or so by dosing something like brightwell Neo-nitro.
Corals MUST have trace nitrates or they will starve, slowly, but surely

You think 12 DKH is ok with no nitrates? I think for sure that can cause coral stress. He can fix PH with a small fan in his fish room.

I agree 12 ain’t good with zero.
I was hoping the poster would just dose nitrates upwards.
Some concern at trying to change both at once.

I would not touch light as you may affect those corals doing well.

You need to get chemistry in check first.

So, dose up your nitrates if your testing zero.
Be sure your test is accurate, zeros a bit unusual with .25ppm phosphate.

No other changes for two weeks.

Sorry if I missed it, but what test kit are you using?

The "advertised" par from the manufacturer is not a good way to judge lighting. Better to advise the type of light, and wattage and tank size.
