Hey R2R members,
I am wondering if you can help me figure out what is going on with a number of my SPS. Tank has been up for over 2 years and have kept all my SPS frags and mini colonies alive and well for that period of time. Over the course of about 4 weeks I have lost a few SPS but a number of other SPS are showing similar signs of tissue necrosis. Parameters are
35ppm- salt
ph 8.1-8.3
alk 8.6
mag-1400-1440
calcium- 435
Nitrate undetectable
I have been trying over the last few months to raise my nitrates to a detectable level by using an automatic feeder to feed consistently 2x a day.
