magnesium reducing green alae

bobparker · 04/28/2008, 07:54 PM

I was reading several months ago that raising magnesium levels in my tank may help inhibit green algae growth. I can't find the thread that linked me to a diy mix. Can anyone help me with finding the proper mix for magnesium sulfate "epsum salts" I could make a paste or soup, but would like to fall in the middle and be able to do it again with exactness.

someone can probably point you to thread but the idea is to gradually raise your magnesium level to over 1500 and maintain it there for a few weeks. Magnesium chloride, not Mag. sulfate seems to be the key to success.

I personally had better results hooking up a Phosban reactor and running GFO.

I read those posts and tried this method for HA. The object is to raise your mag levels up to 1600 ppm and within days to a week people saw results. I did not have any luck with my situation. It only seems to work on bryopsis. I have plain old HA and did not see any effect on it. My corals did perk up and open more so I did learn now to monitor mag levels where I did not before. Even though I wasn't able to rid the HA I had positive results. I'm sure someone here will have the thread. The most results people seem to have had luck with was with using Tech M.
