Coralline algea going away

[Ruth]

Oh Chin I know. I hated scraping it off as well particularly right in the front centre as I would just about have to go swimming to try and reach it. Then my carpet anemone took up residence there so trying to scrape around him was impossible because he would stick to you - so I just left it. The only thing is that my back and side walls are now all green and it's ugly - even with an algea pad or a razor blade it is hard to get off and there is no way I can reach the back wall because of my rockwork and not enough access behind the tank. If it would just stay on my rocks and off my walls I would be soooooo happy.
