Help - Holy Coralline

6 mo. of not cleaning glass probably means 6 months of no water changes / addition of concentrate to dosing unit...

how in the world are your parameters still in spec? that's impressive!

I agree on the flush and nuke option. remove everything and go to town.

Or replace with glass, IMO
 
I have been somewhat keeping up with water changes, probably once a month. I've been testing my Alk about once a week or so and its been rock solid. I dont have to add kalkwasser too often to the reactor as I dont dose too much, just enough to help blow off excess CO2. The calc reactor is way oversized for the tank so it only needs media added once a year or so. Thanks for the idea of the kent scraper, I got one of those around I'll give it a whirl along with my Magnavore 8 with the scraper. Im going to continue the elbow grease approach before doing anything drastic.
 
I got about 30 mins on the left half, I'd say good progress. I'll get there in due time. Definitely got a good arm workout!

 
get a few pencil urchins, they will eat all of it.


I have a pencil urchin and recently decided keeping the back wall clean was too much work and let the coralline take over. Back glass was completely covered and the urchin never left my rocks.
 
i helped a friend clean a tank that looked exactly like this except his tank was made of glass. i broke and bent a few metal blades trying to scrape it off, i can imagine how hard it is clean with a piece of plastic. Good luck
 
Move all your livestock to a new tank then switch out the saltwater with vinegar water to this tank and let it run til the coraline disintegrates.
 
A credit card, and Mr Clean magic erasers. The original kind, not bathroom or kitchen. You can use em in the tank with livestock, and they're like, well, magic on coralline. Acrylic safe, as long as you don't get any sand or other particulates under it while you scrub.
