Coraline Removal - Yes Removal!

reef6414 · Feb 3, 2016

Alright, I'm starting to get some decent coralline growth in my system. Good news right? Well, I love the clean look of a lot of the reefs out there...and am trying to keep the walls of the tank as clean as possible (in wall system with back and side walls painted black).

I am able to remove it from my glass with a razor, that's the easy part. My question is, how do you all remove it from the plastic overflows that are in all our reef ready tanks? I have not tried the razor as I figured it would get caught in the textured plastic and I would have unsightly cuts and scratches in it. Any input would be greatly appreciated!

I used my old i.d. to scrap. It isn't as easy as a razor, but it does work.

Are there not chemicals in the eraser that would impact the system?

I just use a regular glass scrubber pad on my overflow box.
The real trick is to stay on top of it. I scrub it weekly.

Nope. Not if you use the ORIGINAL Mr. Clean Magic Eraser.

Eheim Power Cleaner is what I use. Leave some coraline where you can see it. When you see coraline algae turning white and you did no changes to the lighting or left it expose to air, something is really wrong with water parameters... in my case was the Alk Hanna checker giving too high readings. Gladly I noticed the coraline algae dying, tested alkalinity with a Salifert kit and adjusted my calcium reactor accordingly.
