Hey guys,
I'm having issues with my new acro frags and I'm uncertain of the cause. The frags are 2 weeks into the system and have bleached and recently possibly some RTN. Initially I believed I had hit them with too much light to soon and so after 2 days I reduced the intensity, but the bleaching did not stop. My parameters are stable and test most daily/every other day. 8.4DKH, calcium 450ppm, 1.027SG, Magnesium 1350ppm, PO4 0.08ppm, Nitrate 1.5ppm, temp 29c. I am dosing 2 part with tropic marin trace elements. The temperature is high but stable, and has been historically set at 29c, I believed it was due to inaccurate temp probe, but am now testing via 3 methods which all confirm 29c. I have now realised that the thermostat on my eheim jager has failed, for the second time in just over a year and is stuck at this temperature. Could this high temperature, although stable, be the cause for the bleached acros? My other SPS, LPS and Zoas are thriving. I would also like to add that not all of this batch of acros have bleached, my miyagi tort and acropora yongei appear fine.
I have attached a few examples of some of the acropora frags
Thanks for any help
