It hits some corals and others look like they love life. Tank is 2 years old. Over the past two months I had made changed to lights, replaced GFO, and removed one of two overflows. I run a skimmer, GFO, Cheato with a bright light, calcium reactor, 450 par on the top shelf and 100 on the floor. Corals had been growing better than I had ever seen until 3 weeks ago. I upped the light and burned two corals. Dialed it back down and things seemed to mellow. I thought it was just the lights. Feedback on the forum leaned toward low nutrients and High Alk. My Salifert test showed >.1, leaning toward .03 phosphate, Alk 10.5, Cal 450, Mag 1350, Nitrate <.5.
I turned off the GFO for 3 days while waiting for a Hanna tester. Next test showed .27 ppm po4. Big surprise, but great coral color. Dropped it to >.1 over the past 3 days with lanthanum. Having new tissue loss in some Pocillopora, some Monti, but not all, some frags from dying colony are doing fine. Meanwhile great looking polyp extension from the milli and some Acro and encrusting Monti.
All of the changes other than the overflow have been moved back to what it was when the tank seemed to be bulletproof. The extra overflow is still gone. I dont know where to look? Checked the pumps today for broken impellers or some kind of metal exposure. Sent out an ICP test to ATI two weeks ago to see if there was some way off base target, but I haven heard back. It never takes this long.
PH shift from 8.2 day, 7.9 night. Temp shift +- 2 degrees f day to night.
I have an additional 40g tank that doesn't grow things fast but is always stable. I generally ignore it. I throw SPS frags in it some times. It grows Porites and Monti, Does really well on zoa's and mushrooms. Tested po4 and it was at .40. Also totally unexpected. 1 of the 3 sps moved to that tank did not recover.
Any suggestions as to where to look? What to look for ? Any suggestions for faster turn around with ICP testing?
