Ricordea shrunken bubble??

[FrostyKevin]

My ricordeas's bubbles in the inner ring have shrunk dramatically. I suspect the lighting isn't strong enough, but I want some opinions.

Temp: 78-79F
1.024 ppm salinity
NO3: 25-30 ppm
Phos: 0.20 ppm
Dkh: 8.8

Temperature is too low, you should aim for 80-82. And phosphate is too high, you want 0 phosphate. It could be a lighting problem, or a temperature issue.

I'm pretty sure phosphate shouldn't be zero for ricordea. I'll bump up the and see what happens.
