Coralline Algae on Corner Overflow
I picked up a 125 off Craigslist. Tank is in great shape but it has a lot of coralline on the overflows. Anyone have any suggestions on how to remove it? Vinegar didn't work. I'd actually like to replace the overflows, but I can't find anyplace online that sells them. Any help would be appreciated.

Muriatic acid and water. 10% acid and 90% water. Spray it on with a spray bottle and watch it bubble. Rinse it off with water and repeat until it is gone. Once finished rinse the tank well with water. I just did this on my 210.
Be careful of the mist and vapors, best to do it outside in a well ventilated area. |

Thanks for the feedback. Did the acid discolor the overflow after removing the coralline?

Just get some paper towels and vinegar. Lay the tank on it's back. Soak the paper towels in the vinegar and lay them over the overflow. Let them sit for 10-20 minutes and the coraline should come right off with a soft scrub brush. You can also use a credit card to remove the coraline. Alternatively, just put the vinegar in a spray bottle and spray it on and let it sit for a little bit.

Do like Slief says and see how it works, Vinegar should do it, but the acid will remove the coralline in minutes. I even used it on some lock line I got with the tank. Made it look brand new and it swivels perfectly. |

would it be bad to just leave it on there when starting up a new tank? seeing as its going to get coraline on it anyways?

I'll give the vinegar another try. This time I'll really let it soak.

Ok, so vinegar and a razor scraper did the trick. But the glass is stained where the coralline was. It doesn't appear to be coming off with vinegar. Has the coralline permanently etched the glass?

Personally I would have just left it... We all work toward getting coralline coverage any way. Worst case scenario was that it would die off a bit and help your tank cycle. Best case scenario is that some of it perks back up and seeds the tank. Either way you'd have been fine!

Thanks, but at this point just wondering if I can clean the glass or are those stains permanent.

When I got my tank I ran the entire system with vinegar/tap water for a few days while working off the dead coralline algae. It took a few days w/ a credit card scraping away to get it all. Then I drained it and rinsed it out a few times. |

I was planning to scrape off as much as possible (probably all of it from the glass) and just cycle the tank. Assuming I run a filter sock and skimmer in my sump during the cycle wouldn't that take care of any of the crust/dust that falls off the overflow? |

Dead coralline on corner overflow
So what do you do if your tank is already up and running and there is still dead coralline that hasn’t come off?
