Black Spots

[engelphotos]

So as a beginner there's all these questions that are probably simple to answer ? So hear goes it.

Yesterday did my check on the tank and all parameters are good !! Tank is been running for about 3 months now. I have two fish in Q.T. that will go in display tank in 30 days been in Q.T. 30 days. I have these black small spots in certain places in the tank on the glass and their usually in clusters of several. their difficult to get off with just a magnetic tank brush ? Any idea what they are. I'll take a picture tonight. Also the substrate looks a little dirty what would be a effective method for cleaning the substrate ? I don't wand a sand storm ?

Thanks,

Fred

Pics would help. Are there spots on the fishes, or just on the glass?

Almost sounds like coralline algae but they aren't usually black.

so the spots are only on the tank no where else. not on the fish !! So in the first picture

Your coral is a green hammerhead coral.

You'll learn quicker then you think I've only been doing this about 6 months. I've learned sooo much. That's a hammer coral in the pic. It looks very healthy.
