Looking for some help with water chemistry and corals dying back.
30 gallon RSM 130d that’s mostly modified, leds etc. Tank is about 8 years old. Mixed reef, 4 small fish, clean up crew, etc. Last few months frog spawn, torch, candy canes are suffering. Lost several heads of spawn and torch, and the canes are shrinking back to just a cm or so left on each head. In fact find a few cane heads floating as the flesh has come detached from the stony part. Also lost a few colonies of zoos about 4 months ago.
Media is Purigen and phosfiltrum. Dose kalk 1/2tsp per gallon in ATO and 3-5ml Nopox daily.
I don’t dose anything else. My numbers are as follows. Temp 77, salt 1.025, ph 8, calcium 489, alk 3.9, mag 1400, phosphate 0.25, nitrate 4. Have RODI filter for ATO water. TDS = 0.
tank has always had lower ph until about a year ago when I started dosing kalk.
About 2 months ago my 8 year old serpent starfish died after his Arms started falling off. My numbers are more in range now than they have been in years past but yet the tank seems to be doing worse. I’m certainly not an expert and looking for thoughts or suggestions. Thank you in advance.
