Looking to see if anyone can tell me what this is...
When i built my tank, I used some seeded clamshells I got from addictivereefkeeping.com to help with spreading coralline as early as possible since i'm using dry rock during the cycling process.
I just finished my cycle last month. Since then, I've only added 2 clownfish and some low budget coral to see how my tank is doing. I haven't seen much algea growth anywhere in the tank with the exception of my clamshells. It's a brownish color that rubs off fairly easy. I can't tell what it is. It's only growing on my clamshells and not anywhere else. I'm debating if I should just toss these things out.
Any help would be appreciated. Thank you!
