So I went on a backpacking trip while a friend watched my tanks and since I got back my kenya tree is no longer opening up. I have read that this normally happens occasionally but apparently it hasn't opened up since I left on thursday.
Ammonia / nitrite - 0
Nitrate - 5
Phosphate - .5
Calcium - 420
pH - 8.2
Since thursday the pH has risen by .1, dKH
has dropped by 1, phosphate has risen by .25, and nitrate has dropped by 10.
Barring the coral being angry at my leaving it alone for a few days, the only thing I can think of is an increased phosphate level causing issues.
