That's interesting. I'll have to look into the article in more detail.

I know this wasn't your question but you will have a hard time getting you calcium up with your mag that low. Did you find the silica source? If do don't have it in your water could you have some silica in your rock or sand? Mostly diatoms blooms burn themselves out once the silica source is gone. You can kill the lights for a day or two as well and that will dampen the bloom somewhat. Kalk can also help some with silica.
