Finally an easy solution to bryopsis!

[JB NY]

Water changes will bring down the mag. Most salts mix up to about 1100 mag with a SG of 1.025.

 

[Mr31415]

Because a Mg level of 1600 is much higher than natural seawater and it is not a good idea to keep it there indefinitely.

Nope, no ill effects from the mag. All corals, fish and inverts still look and act normal. The biggest surprise to me is that the chaeto in the fuge deals with the magnesium fine, but bryopsis is killed by it.

have you noticed any increase in coralline growth since upping the Mg?

 

[mazdaghost]

do high mag count affect Anemones. because i have been fighting this for six month and this is the only thing i have not tried.

No, I haven't, but I added a tuxedo urchin and a pincushion urchin to my system in the last couple months and they've been mowing down some coralline forests for me. Apparently they mostly like to eat the stuff on the back of the tank, not the front or sides. They're plotting against me, I can sense it.

My large GBTA is unaffected by the magnesium.

TWallace,
Did you perform manual pruning as it was dying or did you let it "wither on the vine" so to speak?

 

[neelix]

I noticed all snails have been impacted. Mostly the real large ones seem to be in shock. Also the cuke I have seems to be in shock as well.

How are the snails in your tank??

Same here....snails do not like the new high Mg levels in my tank. Everything else looks fine. Looks like I will lose a bunch!

 

[TWallace]

I let mine "wither on the vine" so that the photo series would show only what the magnesium did, not any manual pruning.

Weird about the snails. I didn't notice them have any trouble with the mag in my system. I have about 12 kinds of snails, too. Though some are nocturnal so it would have to notice them have trouble with the magnesium.

The only possible downside I noticed in my system is my pulsing sinularia turned paler, almost white. Some toadstool leathers also turned whiter, but my green polyped toadstool leather was unaffected. None of those corals look like they're in danger of dying, though.

 

[Peter Eichler]

Even at 2200+ ppm my snails were just fine. Astrea, Turbo, Stomatella, and Cerith mainly.

 

[Znut Reefer]

Interesting. T.Wallce do you have many acros in your system?

 

[TWallace]

I have 2 acros, but I'm pretty new to SPS. One is a bali green slimer which is doing great, the other is a mille which isn't so great. It only extends polyps at night. The mille was bleached when I bought it because the store had a pump malfunction which electrocuted the tank. It lost its color as a result, but had good polyp extension in the store and it was cheap, so I bought it. I have several other SPS which are all doing great: pocillopora, stylophora, hydnophora and montipora capricornus. None of them were affected by the magnesium overdose.

go to sponsors site that sells randys two part sytem can get the mag cheap

1 box epsom salts, 1 qt of water = lots of mag supplement..

Any grocery store is selling his 2 part btw :lol:

Nope. It is mentioned specifically you want Magnesium with Cloride NOT sulphate - as is the case with Epsom salts.

 

[jdieck]

Right, some of the negative effects may be due to excesive Sulphate ions comming from using only Epsom Salts.
Ideally you want to use a mix of 10 to 1 Magnesium Chloride (MagFlake) to Magnesium Sulphate (Epsom Salts).
If you will be using MagFlake be easy on it and do not increase magnesium more than 50 ppm per day and watch for Ammonia which might be the other negative effect. Although MagFlake has been safe to use it is produced using a process with Ammonia. Limiting the daily increase will give the system a chance to process any ammonia that may be present.

 

[neelix]

Hmm that would explain it. Iused the 2 part formula, maybe 2 much on the epsom salts??

Depends on what you used for your part 3, Even if you used the mix of Epsom and Mag Flake that is only a ratio of 5:3. Because the Calcium part adds Chloride and the Alkalinity part adds Sodium, the mixed part three in proportion of 5:3 is right as you are already adding some chloride with the calcium part but used as a Magnesium supplement alone you need to up the chloride portion of the supplement by making it 10:1

Just to make sure I have this straight, you are saying 10 parts mag flake to 1 part epsom salts? The formula I used was 7.25 cups mag to 3/4 ES. Since I use kalk for calcium support.
