Treating Bryopsis with Brightwell's Hydrat Mg

[teebone110]

Came across some good information and thought to share incase it helps someone. I'm wondering if anyone has successfully treated byopsis by increasing their magnesium level?

It is a very tough algae to eradicate, since many clean-up crew will not touch it.

The first step is to ensure that you can identify it as bryopsis
(This is not from my tank ??? Got these pics from another thread)

Bryopsis looks like green hair algae from a distance

and up close, it has a feather-like appearance

I have read many threads about treating it by increasing magnesium levels to 1800 ppm and holding it there until the tips start to die and wilt away, sometimes it takes a few weeks.

People recommend using either Kent Tech-M or Brightwell's Magnesium.
I found some Brightwell's Magnesion-P and thought I would contact Brightwell to find verify the proper dosing for my water volume and whether this would actually work.

Chris Brightwell is the marine scientist and president of Brightwell. He corresponded to my question and recommended that I not use the Magnesion-P formulation and instead use Brightwell's Hydrate-Mg.

Not sure if I will do it, since my problem isn't too bad, but just curious about others thoughts? I have read that many who have utilized this treatment experienced no adverse events with their sps, etc.

Re: Treating Bryopsis with Magnesium

I Thought what i had was hair algae until you posted this link  :?

i guess i have bryopsis too

I have heard of this and have had a couple of customers try it and keep it consistant at 1300 ppm and it has worked for them.  Good post though and I am sure it will help a bunch of people as it has already helped one.

Did they use the Brightwell's Hydrat-Mg formulation?
This product is designed for maintaining Magnesium levels of 1500-1800 ppm

In some instances, marine and reef aquarists may find it beneficial to maintain the magnesium concentration in their aquaria within a range of 1,500 - 1,800 ppm for prolonged periods of time. The period of time will vary between systems and is completely dependant upon the magnesium concentration that is maintained, as well as the extent to which maintaining the magnesium at an elevated concentration is associated with obtaining the desired results.

Additionally, evidence suggests that the specific magnesium salts utilized are important to obtaining the desired results. Hydrāt-Mg is a concentrated magnesium solution that makes use of these specific, hydrated (not anhydrous) magnesium salts, in proper ionic ratios. Brightwell Aquatics Magnesion and Magnesion-P are composed of anhydrous magnesium salts, which offer greater purity than hydrated salts; Magnesion is also more concentrated than Hydrāt-Mg. Regardless, the conditions that would dictate that the magnesium concentration in a reef system be maintained within a range of 1,500 - 1,800 ppm are, in most cases, more rapidly addressed with Hydrāt-Mg than with magnesium supplements composed of anhydrous salts. Choosing to maintain an elevated [Mg2+] for an extended period of time assumes that the aquarist understands the impacts and potential risks that doing so can have on a marine aquarium.

I believe it was Kent's tech m.

I wouldnt try it ....I have heard good and bad things.  I also read that it's only one brand that works and they think its an impurity in it that does the trick....not the fact that Mg is high.

It might be kents.

I think it still is an impurity found within the hydrated formulation of the magnesium, (not anhydrous).
It's possible that Kent-M might consist of a hydrated formulation too?

A mag level of 1800ppm seems crazy. I have had mine over 1600ppm before and things seemed okay.
