This is my first post on the forum. Forgive me if I’ve posted in the wrong place. On April 15th, I added a fire urchin. It was vibrant in color. This week, we noticed that it appears to be losing color. Spines are intact. It has loads of algae to eat and does a great job cleaning the rocks.
Here are the tank specs:
90 display/25 sump
Reefmat and skimmer for filtration
Weekly 10% water changes
The number below have been stable with exception to calcium and magnesium. We’ve been trying to raise those slowly.
Tank is 5 months old
Temp 77
Salinity 1.024
PH 8.2
NH3 0
NO2 0
N03 20ppm
Pho 0.009 ppb
Calcium 430
Magnesium 1160
KH 10.4 dkh
Testing with Red Sea and Hanna
I know phosphates are lower than they should be. Algae seems to eat it up.
I’ve attached photos of how he looked on April 15th and as of today. This is an awesome creature. I don’t want to lose it.
