High MG Levels

OK, So my MG levels are over 1500, I run out of the 1ml which is 1500 and it is still pink so somewhere over 1500.

Two questions.
1.) How bad is high MG for the inhabitants ?
2.) How can you lower MG amounts ?

If you do water change, the salt has MG so that doesnt seem to help. If you fresh water only, then my salinity will go down.

Any ideas on how to lower or should I not worry too much ?

The extra magnesium will eventually be abosrbed. Don't worry too much. It will stabilize in a week.
Just check the health of corals and fish in your tank.

 

Well, no corals yet, just a few shrooms. Without corals will it still be absorbed somewhere ? It has been 2 weeks and I did a water change in there somewhere.

 

Hi, simply allow more time between water changes (4 weeks) and it will fall naturally. When you do mix a batch of new water for a change, test it to see how much Mag is in it and this will give a better understanding of what is going in. While you are delaying your water change, test Mag weekly to Gage the fall off rate.

 

How did your MG get so high? are you dosing anything?
Like unclejed stated it should fall naturally.

 

When I started dosing MG and CA, I obviously dosed too much. I guess I will wait it out and stop dosing MG for now.

 

mg at 1500ppm I consider ideal, just keep a close check on the ca, if not low by now
eventually will drop some

 

It will get absorbed, and some will get skimmed out as well. It's not THAT high where it will cause problems. Coralline algae growth need Mg as well as Ca. Keep an eye on your dKH as well as that will keep your tank from snowing. Just make sure all 3 elements are in balanced proportion and it should be fine. I keep my Mg just under 1500, Ca at 500 and dKH at 12 and my rocks are starting to grow purple, pink, red and orange color.

 

Many people raise Mg to 1600 to help erradicate bryopsis... There should be no issue.
What salt mix are you using? Opp, I just noticed you said you were supplementing, sorry I read fast.

Happy reefing!!

Trendy Magnesium Solution
Some reports of a Bryopsis bloom mysteriously correct themselves over time and in fact, may disappear altogether where water quality is kept in good standing. This may go a ways in understanding why some people are insisting in the latest trend of elevating the levels of magnesium from the normal range (1,280 ppm) to 1,500 – 1,600 ppm. Most aquarists who have tried this method feel it is the fastest and least detrimental way to correct the dilemma. The theory behind this is that the magnesium stops the photosynthetic processes in the Bryopsis, but does this without affecting other desirable macros and life in the reef. There are some, though, that suspect the elevated levels of magnesium can kill desirable invertebrates, so as with most things in reef keeping, slow is best. Also, ask yourself, would you rather chance losing some snails or some corals?
You decide.
