Are my parameters ok?

[Reefhaven]

Just got my measurements back from ATI. Are these pretty reasonable? My cal is back to 428 and the mag is 1330 since the test. Still having sps rtn from the tips but polyps are totally out. Torches are bailing out. After doing a weekly water change things get better for a bit. Tank is 230 gallons and been running for over 4 years. Had a huge crash (lost everything) about 2 years ago but left everything running. Ever since then when I add sps or torches it starts to die.

What about alk, n03 and po4?

Alk is 8.28, nitrate is 6 and phosphate is 0.03

You might or might not benefit from a trace element supplement. I’d personally feed more to get phosphate a bit higher.
