Finally an easy solution to bryopsis!

I'm on my second day of dosing Tech M. My Mg level is very low so it's gonna take me quite a few days to raise it up to 1500ppm. I have taken a before picture and I'll post it as soon as I get some results. :)
 
There's some speculation that increasing magnesium too much at once can cause some corals to bleach. I think some people reported snails dying from it as well. I never experienced anything dying from boosting magnesium, but my toadstools and a sinularia bleached, then later recovered. Also, some zoanthids seemed less vibrant, but also later recovered.

Why not? What happens?

What TWallace mentions usually comes from impurities in the supplement. In the case of commercial supplements like Tech-M the risk is lower due to their source of raw material and quality control. In general it depends on the process used to manufacture the main ingredient Magnesium Chloride, it might have Ammonia as a result if produced by the Solvay method so in some instances you may create an Ammonia spike. The idea of limiting the amount supplemented in one shot is that in case there is ammonia in the product, the system has a chance to process it before the next shot is added.
Even some high purity Magnesium Chloride Hexahydrate analysis I have seen are allowed to contain up to 100 ppm of Ammonia and typically contain about 50 ppm, similarly high purity may contain some Arsenic, Lead, Aluminum and similar so caution is advisable.

That's good to know. Thanks for explaining that. I never knew the reason why, and just accepted the recommendation for what it was and tried to follow that guideline.

What is bothersome is that we assume normally that if we did not have problems with one product then it will stay that way forever.
One of my concerns has always been when using materials not intended for the hobby we are running a risk that the manufacturer changes the spec and we will not notice.
As an example, because bromide had never been a specification of Calcium Chloride Dow Chemicals in their manufacturing starting 2006 stop the portion of the process that removed the bromide. As a result products we normally use like Dow Flake, Peladow or the food grtade of anhydrous Calcium chloride saw their content of bromide increased from the level of 150 ppm to levels of 7000 to 8500 ppm by weight.
This has a lot of implications for people using Ozone and or UV sterilizers as bromide will turn into very toxic bromine compounds.

So how do we sweet talk these guys into extracting the bromide again?
 
Create a market for it :D
It seems they were extracting it to sell it as a by product and the market did not worth the cost so it could have been a cost saving action, who knows.

So the handful of us that needs it isn't enough of a market?

You mean the bromide? Are you into biocides?
 
I meant we all need the Magnesium Chloride for our hobby, so if the mfg's of Mag Flake would take that into consideration and continue to create a nice safe batch for us it would be appreciated.

I know we don't use nearly as much of this product as they sell to melt snow and ice, but if they could do limited runs like ESV does for B-Ionic, clubs across the nation could order it a pallet at a time annually.
 
I'm not getting this, I'm on my third day dosing kent tech m, but my magnesium level is dropping each day lower and lower. What's causing this??

I think the market will still be small. Actually high purity is produced but is too expensive for our purpose so basically what has been reaching the hobby in commercial supplements is the food grade low ammonia type. Same quality used for pickling.

How much water does your system contain, how much tech-m are you adding and what is your present level of magnesium?

The magnesium is at 930ppm right now so it's very low. I haven't done much with it since the bryopsis went crazy cause I hate to look at it. It's a 55 gallon with a 10 gallon fuge. I guess I wasn't adding enough or something, I used that little cap thing that keeps the gallon bottle seal during shipping and dump 3 caps of that at a time. I used a syringe tonight to do the calculation. I think I might of over done it tonight by dumping 110 ml of this solution into my tank.......We'll see what happens tomorrow when I re-test it..... :eek2:

110 ml of Tech-M will increase Magnesium by about 30 ppm in 60 gals of system water.

You will need 325 ml per day to increase the max recommended of 100 ppm per day; so, assuming your initial test of 930 ppm is accurate, a total of 1200 ml to increase your level to 1300 ppm and a total of 1,850 ml to increase it to 1500 ppm

So you still have about 5 daily doses of 325 ml each to reach the 1500 ppm.

I would recommend a water change to help normalize the levels and to check calcium and alkalinity and adjust them if necesary to 420 ppm and 10 dKh if necessary.

You can use the chemistry calculator to help you determine the amount of supplements to add.
