Ever since I moved my lights the tank took a turn for the worse. I did cut back on intensity two days ago. The leathers in pic are cheap and have been since I upgraded.
This is why I hate touching anything; the slightest change and poof.
Added BRS calcium powder.
Added baking soda for Alk, Randy Holmes recipe.
Added powder BRS Magnesium.
Added Phosguard to sump.
Lowered light intensity.
Did a small 10g water change.
Added 3 small urchins, penny size, all they had.
