Well I finally got around to giving the tank a good old cleaning. I made up some water.
Pulled out what dead frags would come out.
Scraped as much gunk off as I could then changed the water.
I just gave the tank another scrape and have another batch of water ready to go, so I will be doing a water change soon. Tanks looks 100 times better and I think I will be ready for another clean up crew next week.
