I put this frag in and it was open and seemed good for 5 weeks, then it closed maybe annoyed by hair algae but mostly I've been able to get rid of the algae, but they still have not reopened for 5 weeks now. Can anyone see anything in my photo that might cause them to close, water parameters have all been good and unchanging, though I have not tested for phosphates. I recently ordered a kit. Light has been on the low as I hoped they were acclimating.
