fishbulb,
i've always used seachem mg, which i think is magnesium chloride. what's the dosage like on the epsom salt? thanks.

Has anyone considered that the concentration of Mg or sulphate has nothing to do with the abundance of Bryopsis. Afterall, there's no reason to think there should be any relationship

Why? Why would elevated Mg or SO4 be in any way harmful to Bryoposis or any other algae?

I don't know why. I also don't know why Raid Ant Bait kills ants, but it does. I believe a thread full of first hand experience by people who raised their Mg to 1600 pm and watched their Byropsis completely melt away. Again, this is algae that they had for months or in some cases even years and suddenly it was gone within a couple days of raising the mag. This is with a lot of people. Obviously it works, I just don't know why. Read the thread. It's pretty hard to imagine it just suddenly died on it's own for no reason.

There is a "sticky" thread that shows that elevated Mg levels are harmful to Bryopsis.It also appears that it seems to only affect bryopsis sp. & not other forms of algae.I have done a few google searches & there have been a few lab type results posted that seem to support the evidence.I currently have an outbreak & have just started to raise my Mg levels.Hopefully I will be able to report back with good news.Apparantly the boosted Mg directly interferes with the bryopsis' normal processes,without affecting most other lifeforms(some people have reported loss of snails).HTH

also there are definately some heavy metals that do contribute to growth,such as molybdenum/strontium for corraline algae growth.

yes that is true but mcsaxmaster will deny it to his grave.haha.

There could be a lot of things going on, and there's no reason to think that somewhat elevated Mg or SO4 is in any way harmful to Bryopsis (or much else). There do tend to be a lot of impurities in magnesium salts though, perhaps one of those is responsible?...

Holy heck no. Firstly, molybdate is a nutrient used by nitrogen fixers in miniscule amounts, so it most certainly isn't a heavy metal, and it is a nutrient only to N-fixers. Coralline algae don't use it whatsoever. Strontium is incorportated into the skeletons of calcifying organisms at about the same concentration as it occurrs in sea water (though there might be a bit of fractionation). There is no evidence whatsoever that it increases the rate of growth of any organism. By your logic lead, mercury, and uranium should increase the growth rate of coralline algae :eek2:

So are you saying no organism utilizes heavy metals?
MCsaxmaster

I'm saying no organism uses heavy metals as a nutrient. Heavy metals are variably toxic, therefore increased abundance of a heavy metal can result in anything from no harm to severe harm to an organism depending on concentration and the ability of the organism to detoxify the heavy metal.

isn't magnesium sulphate used to fetilize plants because of how well it disolves in water (this is also known as Epsom Salt, used in this hobby as well)? I'm pretty sure magnesium is essential in the developement of chloroplasts, so I would assume that Mg actually benefits photosynthetic algae. Am I wrong in this inference? You can raise Mg with epsom salt, as it disolves fairly well in water... something like magnesium sulfide hetrahydrate or something (when placed in water).
On that note, I don't think raising Mg levels will get rid of Bryopsis, although I am not sure of the effect of extremely high concentrations of Mg.

If you put a large amount of snails and mitrax crabs they will become very good at cleaning hair and red slime /bubble algae from your tank....this only happens if you have what seems to many as to many....you need very large turbos to trim dowm the hair then all the snails can do the job for you....you remove the snails and crabs as they get large as they will turn over corals....sallylightfoot crabs are one of the best hair algae eaters their are,if you look at their small claws they can not catch any heathty fish....Most of the people on the net give bad advice or make simple algae problems into chem problems....keep adding small snails and crabs as you remove the large ones and you will never have any problems....

credible scientist have done credible research and have concluded that heavy metals do help to increase growth of algae.and yes it was heavy metals including aluminium,and copper.it sounds crazy to me but i cant deny their results.
