I have a 55gal tank w/ HOB refugium & crushed coral bottom.
Ive had a problem with NO3's. They have always been high since the tank first cycles 4 months ago.
I have added a 8oz bottle of Copepods 3 times. (lights & filters off) with he hopes of having a Mandarin someday.
The last water change 3 weeks ago, (40%) I let the water change bucket settle and drained it down to 1/4" of water.
It was FULL of copepods! I used this water to populate my refugium.
Last week i did a water change and 1/3 bedding change to Sand & I did not find a single Copepod.
My NO3 reached 40-50ppm. (before water change, now 20ppm)
NH3/NH4 & NO2 @ Zero
Salt, PH & Alk normal
Cal 420ppm, Mag 1100ppm
Did this kill my Copepods? Is there something else that could do it?
Thank you.
