So I'm finally here to discuss an "issue" I've run across with little, to no changes through personal assessment. I have a 90 gallon with a 33 gallon sump. Very heavily SPS populated with some LPS. I've been stuck at 0.00 pO4 and difficulty raising dkh. There has been additional colonies added to the system over a fairly short span. I figured chemistry will take some more frequent attention as they settle in. Ideally I planned 2 to 1 times a day testing of alk and pO4. Over time of monitoring these numbers have the fastest impact on basic health. Coloring is a different story. Lighting, flow, trace, temp, and other stable base parameters ect. I've been researching p04 relations to par and flow. Par is not measured. I know it's decent. 36 x 24 x 24 dimensions with AP9X (4) t5 with (2) blue plus (2) true actinic and a custom built led strip with 470nm- 405nm 3w each x 27 diodes on the front hybrid fixture @50° to the back with 120° lens. Base start is TM pro reef. Currently dosing 120ml TM balling A, 130ml of TM balling B, 120ml of TM balling part C. CaL remain 400 ppm, 6.5-6.2 dkh and mag at 1380 with TM bio-magnesium, 10ml of TM A- and K+, an additional 10-20ml brs sodium bicarbonate x2 a day, (yes dkh is under "ideal" number. Preferably 8.0, at least) just trying to avoid swings and increase slowly. Dosing TM phyton powder and zoo powder, 1 scoop, 2x a day benepets 1/2 teaspoons with 1x 5ml of acropower Amino. Feeding fish 5 frozen cubes. Fish eggs, spiralina brine, (2)brine, mysis mixed with oyster feast and 5ml of acropower. I feel like adding a lot to still register 0.00 pO4 per Hannah HI 713. I've read about carbon locked system per neo phos directions. I know a lot of specific info but hey!
