My tank finished cycling about 3 to 4 weeks ago. Been great so far, I added two clowns and 4 cromies so far and a 1 banded shrimp, 4 hermit crabs and 1 jawbone which hides in his hole. I am using RO
water from glacier vending machine. I have base rock and live rock from fls.
This week I noticed brown coloration on my rocks and sand, live rock has no issue still beautiful. Can someone tell me what's going on? My water parameters are great 0, 0, 20ppm, temp 76 and ph 8.2 and everyone in the tank is great. Just weird that brown colorization is happening..
