Mangroves and Magnesium

I was down in my old stomping grounds of Sarasota a few weeks back and I found myself checking out the local Mangroves whenever I had the chance. They do a lot of kayaking out on Lido Key where apparantly they have pretty elaborate mangrove networks, manatees, etc.

Anyway I stopped by one of the local reef stores to see what the local market was like and he had lots of Mangroves growing in his fuges. I have never seen nor read anything comparing the nutrient export of Mangroves VS Macros, although I agree that mangroves win easily in the coolness factor. But what really struck me was that the shop owner told me that Mangroves really deplete your Magnesium. That in my book is a huge negative and makes macro a no brainer in my book as the top-dog for biological nutrient export.

I know of one ARCer that has a gorgeous system, including Mangroves, and had shockingly low MAG (<1000) and was having difficulty understanding why. Makes sense that its the Mangroves.

Interested to hear other thoughts, opinions, and experiences.

I found this mangrove video Thomas done on mangroves with Julian Sprung [well renown in ReefKeeping world] at MACNA 2013. The interview with Julian Sprung is located between 12:00 to 17:15 of the video. An important part of his interview may help you [located at 16:23 of the video] where Julian talks about the filteration process of mangroves.

I hope this information is helpful. The link is: http://www.youtube.com/watch?v=RiqjwhRA_Eo">http://www.youtube.com/watch?v=RiqjwhRA_Eo</a>
. It can also be viewed under the MACNA section here at ARC if you are a paid member of ARC.

Magnesium is absolutely essential in chloroplast construction of plant life, so yes. How much, I don't know. I suspect regular water changes should far exceed the effects of mangroves commonly found tied to our systems. On other words, one or two shrubs on a 100 gallon system, no effect. Full grown tree on same setup, maybe.

Riverview Class of '95

I can't believe how much that area has developed. Downtown used to be dead now it is vibrant with tons of investment.
 
I've got 6 1.5' plants on a 150 gallon system and have been struggling with keeping Mag up....
