50% water change and still 20ppm nitrates

[Milad]

about 20 total fish, bunch of them are small with only 4-5 fish i would consider large (3"+)

I do 10% water changes weekly on the money

Salt is stirred for 1 week

Skimmer runs 24/7

Lights are on a timer

Autotop off is set with RO/DI water so the level is solid

Ive reduced feeding in the last week to almost nothing, enough that someone took a huge bite out of my xenia

I felt bad for the tangs so ive feed them a small piece of nori (1x5) last couple days.

I'm fine with not doing anything but this wasn't something that has been around this whole time, thats whats bugging me. All of a sudden all these things went wacko.

ill get a phosphate kit and test it out.
