hey guys this is my first post here.
first my question, then background on the tank.
i have a piece of white coral and crushed coral as substrate.
having read some threads here and google searches i've decided to get rid of the crushed coral, but until then.
my coral is turning a weird color. i noticed it a couple days ago only on the large piece of coral. i took it out and rinsed it under my tap. the "color" came off as soon as the water touched it.
today i wake up and my crushed coral is turning the color and my coral piece is that color again.
i tested my water 2 days ago, right after i first noticed it on the coral piece.
my results were
ph = 8.2
ammonia = 0.8 mg/L
nitrate = 0 mg/L
nitrite = 0.2 mg/L
alkalinity = 3.0mEq/L
these tests were done with the instant ocean test kit.
i did a water change 3 days before i noticed the color (5 days ago)
tank back ground:
the tank is 20gal
it was set up 3/27/07, on the 30th i bought fish. i had 6 damsels in the tank, i listened to a guy that thought he knew about tanks. now i have 3 damsels left cause the others attacked them.
now i know that 6 was way too many fish.
so any help would be great. i'm really thinking about putting the fish in some containers and starting over with sand, but i really want to figure out why my coral is changing colors before starting over.
here are pics of the coral piece, the crushed coral pics didn't come out good.
