Coraline in freshwater?

[phoenixkiller]

What would happen if a very small amount of dead coraline was placed in a freshwater tank?

P.S. I ask this because I got a whole bunch of supplies from a guy on Craigslist. When I went to pick the stuff up, I realized the supplies were used for a saltwater tank, and were covered in long-dead coraline. I actually scrubbed most of it off, but I absolutely could not get the coraline that had grown in the nooks and crannies of the supplies. So I was wondering if a very small amount of coraline would release ammonia, mess with my pH, etc.

I would soak in bleach before using it.

Ok. But is bleach dangerous to fish??

No reason to use bleach IME. Soak a paper towel in white vinegar and lay it on the affected area for a few minutes. The vinegar will soften up that coralline so you can easily scrape it off. I have done this with numerous glass tanks, and also with a 4'x4'x2' acrylic frag tank because I couldn't use my glass scraper (would scratch the heck outta the acrylic). It worked perfectly. Rinse well and you'll be good to go.

Ok, will do. Any idea what would have happened if I had put the equipment in the tank WITHOUT getting it all off?
