Sps issues

How is everything starting to look?

You should get phosphates up higher. I recommend turning off the refugium and running a cryptic sump for now.

I would also crank up those lights significantly. With those lights I would run all channels at 100% or near that level for half the day then reduce whites / go heavy blues for second half of the day.

So here is an update on where I am at, Lighting changes got the ATI back today.

Still struggling with SPS but only been running the G6's for about a week.

Parameter	ATI result	Assessment
Salinity	29.91 PSU	Critically low
Alkalinity	7.87 dKH	Acceptable
Calcium	441 ppm	High relative to measured salinity
Magnesium	1,160 ppm	Low for a 35 PSU reef
Potassium	298.5 ppm	Low
Iodine	1.35 µg/L	Critically low
Molybdenum	1.41 µg/L	Critically low
Strontium	10.11 ppm	Elevated
Nitrate	11.58 ppm	Reasonable for a mixed reef
Phosphate	0.06 ppm	Within our target

Equipment / Setting	Current status
Main lights	2 × EcoTech Radion XR15 G6 Pro
Spectrum	AB+ preset
Intensity	50%
Previous intensity	75%
Previous lights	2 × Red Sea ReefLED 90, removed
Supplemental lighting	Orphek OR4 UV/Violet ordered; installation not confirmed

So you have changed two 90W lights for two 105W lights. That is not going to make any significant difference.

The AB+ schedule dims down whites. You don’t have the extra power providing the wiggle room to do that.

Most important issue is find a reliable way to measure salinity. Least brain damaging is Tropic Marine Hydrometer or reliable refractometer like the VeeGee STX-3

For lighting, if you want to focus on SPS you need more lights. I have the same rank (ie, RedSea 525) and am SPS dominant. When I was considering Radions I was planning to go with three XR30 or six XR15. I was also going to supplement with two of the five ft AI Blades. With your current setup it is okay with mixed reef. Even then I would run the lights for at least half the day all channels at 100%.

I am old skool, i am not replying to dicate/disagree with any fellow reefers.
My reply is from my experience.
Maintain simple sea water parameter's

35ppt
Mag 1280+
Ca 400/410
Alk 7/8

Quite a post, srry, i bypassed most of it!

Maintain ph above 8! , Regular water changes will supplement what you don't manually dose, I'm not referring mag/ca/alk,. You are only keeping water.. It is Simple!
