Nice. How'd you manage three tangs that get along? [emoji50]Update:
25 gal water change yesterday. Things still looking pretty good, I continue to occasionally touch up areas of the rock but it is very manageable. Continue to dose nopox and it may be starting to show results as nitrate has come down.
I tested the water before the water change:
No3 4ppm
Po4 0.0
Kh 10.1
Ca 450
Mg 1560
Ph 8.21 avg
Tmp 78
SG 1.026
Took a little video.
