Did a par reading at the end of match and it's about 200-220 with the screen on. Taking the screen off adds about 100-150 par but I only do that for about a half hour to hour a week for water changes and stuff.
Water parameters fluctuate between these ranges always
Po4: 0.07-0.14
No3: 9-15
Alk: 7.4-9
Ph: 8.0-8.3
Salinity: 35-36
Salt was always hwmarine but have recently switched to red sea blue bucket a couple months ago for consistent availability.
This icp test is from April and shows a bit of elevated tin but and I have cuprisorb on hand just in case but I've been told not to worry too much about that and just check equipment as all these companies seem to show different metal results when given the same sample.
I occasionally add 5 ml of iodine a couple times a week. A couple of my gonis also seem unhappy...while the others right next to them seem to be thriving. I think I need to start adding some manganese for them. I think I'll start dosing that and do another icp test soon
I hope it isn't nudibranchs... I was thinking during water change this weekend I'll pull that frag off and relocate it somewhere to see if it recovers in higher flow, its grown onto the rock there on both side of frag and that newer growth seems fine and separate from the frag issue so far. So I'll reef dip and iodide dip it first and see what falls off. Do sps like iodide dips the way lps seem to love it?
And the flow pumps are on either side of that rock on back of tank so the only flow it gets is the water on top flowing back to the overflow
