Example of my last test, measured after I topped off with 1 liter R.O. to
the "full mark" on the tank

Size 55 gal plus about 10 gal in sump 3 inch DSB. 7- pounds rock. 4 JBJ 55W
( 2-10kk, 2-actinic) with 1 Sailfin tang... misc. critters are doing well,
No outbreaks of illness, or weird algae's, blah... blah...

Salinity 1.024
Temp 79 F (varies from 78F to 82F with room temp and lights being on/off)
pH 8.3 ( stable within 0.1 for over 5 years)
Amm. 0.0
Nitrite 0.0
Nitrate less than 0.03
Phos, 0.1
Copper 0.0

This listing will tell you this an established tank, and not only that I
THINK its ok, but you have the data to show what is going on.

Before the folks in this group will try to help you, you need to show that
you have the initiative to care for a tank. If you are experiencing a
dye-off, then everyone would assume that you have done a round of water
tests. They want the readings. What's the temp, specific G, where does
your
top-off water come from.. etc... No one will reply to "My water is
good..."
