My Urchin isn't making a dent in my Coraline. Atleast he aint starving HAHAHA

I gave up scraping the back glass and have learned to live with it...sort of

marie, i dont think you'll ever have a coraline free tank

I stand corrected :biggrin: I suppose that since they have tube feet, this wouldn't be a difficult task.

Yup, they climb the glass!!!!!

Let your Mg drop down below 1000 and you will see a bleaching/die off, learned this the hard way :cry:, couple weeks of dosing has brought it back pink as ever though.

This might not be the best suggestion for a reef tank, playing with your parameters to kill stuff usually ends up killing more than you want to kill. IMO coraline is nice on the back of the tank, just keep scraping it off on the front/ sides, keep an urchin and you should be good to go.

Not a suggestion, just a hard learned lesson. Coralline is part of a reef tank and something one should be willing to live with in a healthy system.

Just stick one of these onto the back of a Magfloat and say goodbye to coralline:

Dollar for dollar this thing is the best buy I have ever made for my tank. It cleans coralline of the back glass with ease.

I will never use another cleaning magnet in my life! I find they scratch up tanks pretty bad if you leave them in the tank all the time or get even one little sand grain caught in it. Even the coralline stuck in the magnet seems to scratch the glass!! :eek:

I just use the long handled scrapers, and find it's an easy job with the replacable blades. Just keep the blades replaced. I use a scraper that uses household blades so it's super cheap. :D
