Does anyone here have recommendations to keep purple/coraline algae from growing on my glass? I'm scraping it off with a razorblade, but would like to not have to do this. It reforms pretty quick.

Thanks

Thanks Metal and Wake. I need to start that. I have one, but don't use it. I appreciate the advise. I do notice that it won't take off coraline that is already there, but you have a good point, in using it to prevent it from starting :-D
