ICP result, can you take a look ? thk.

[Patx]

quick history:
old 10 years tank, dino/cyno struggle for 2 years... (im good at keeping no3 and po4 at zero )
motivation down, i let the tank alone (only top off) for around 3-4 years.
coral died etc...
refugium (15g) cheato all good and totaly healthy ! (adding kno3)

the 4 past months im back on it.
big 50% water change, purit and polyfilter.
change sand (live) (1inch max)
dosing carbon (mix : vinegar,vodka and brown sugar)
microbacter7
Tank, 2 months blackout.

light on now for the past 2 months.
fish in doing great.
some diatom at first (gone for now)

working to balance NO3/PO4 whit KNO3/KH2PO4/fish food and the % of the led on the refugium (toward more on fish food and light the past 2 week)
almost there !

thk for any input (i think the results are good/not that bad)
should i use a silicates remover for the ro/di ?

ps: no coral for now. aiming for zoas, rico and montipora.
10% water change/weekly...

Those values all look fine to me (nothing concerning catches my eye). I would be happy with those numbers, including Si.
Salinity though looks low and I'd check my salinity calibration and measurements.

 

[Patx]

yeah, i have a m887 refractometer that i suspect to always be on the high side. (whit good calibration )
the sample i send was reading 1.026... i will target 1.028.
and keep calibrating whit 0ppm water....

for fun... my test vs icp (icp sample was test at 11days old)

If you have doubts about the salinity I recommend the Tropic Marin hydrometer. Ya can't beat simple physics for accuracy imo.

The salinity looks a bit low and I'd raise it.

Phosphate looks quite high.

 

[taricha]

The reported PO4 that I see is 0.03 ppm. Which is a fine target, unless I'm misreading the report.

po4 high ... huh ?

ICP: https://lab.faunamarin.de/fr/share/analysis/329471

55 gallons system.

Aquaforest reef salt.
23ml AFR/day
K+ 1ml/day
A- 1ml/day
Po4 maintain whit kh2po4. (Around 0.15)

Refugium, chaeto/xenia.

I think that i don't need to dose more k+/A-

What do you think ?
Something special to look at ?

Coral ok.
Some GHA
