Nitrate?

[bertoni]

The tank might need some time to become stable again. How long ago was the tank rearrangement done?

Neither nitrate nor phosphate are likely to cause soft corals a problem. If the alkalinity is extremely high, that might be an issue. Typically, that's caused by the use of pH buffers, which are all just high-pH alkalinity supplements.

Thanks thats what I was looking for.
The rearrangement was done almost two weeks ago.
I'll try and keep my hand out of the tanks for a while, Should I wait a few days to add more sand, Or just get it over with and stay up on water changes?
Thanks again

(edit) If you look to one of the first posts, I have been trying to raise ph throught the use of PH up ( sodium bicarbonate) I added 3 tablespoons with no affect.

How can I raise PH? I'm stuck at 8.0

8.0 is fine, especially if that was measured in the morning. I'd stop all the alkalinity dosing (which includes baking soda) until the alkalinity reading shows dosing is needed.

Baking soda lowers pH, when added to the system, and then causes a slight rise after the carbon dioxide produced is outgassed. It's not useful for pH problems per se.
