Thanks,
This Elevated magnesium thing is perplexing.
I would love to try this test and share the results, but I checked the medicine cabinet & pantry.. no Hydrochloric Acid.
Is this google find related?
"Do not use a strong base, such as sodium hydroxide, to neutralize a strong acid like hydrochloric acid. ... The sodium bicarbonate will not neutralize the spill, and acetic acid could react strongly with the base. If you spill an acid or base on your skin, immediately wash well with water.
Laboratory Safety"
Came across this because im having the exact same issue. I only dose kalk, And use salifert mg kit (3 test in a row yesterday), my salinity is always good and check daily with properly calibrated refractometer. I AM however doing weekly 15% water changes With red sea coral pro, but that would make it stay more regulated I wld think. My mg is at 1560-1600. Calc 445 449 alk 8.5 ph 7.9 8.0 nitrate 0 phos 0.0. I wouldnt care too much if everything was growing fine but My corals arent growing and even took a downhill turn past few days. Esp, torch frag keeps receeding and cant figure out why. I feed alot & even target feed. So checked mg, which I hadnt tested often.
I think that Mg wasn’t being utilized either so the Mg in the kalk and that in the water changes caused Mg to build-up as well.
.
Possible mg precipitation issue due to ionic imbalance? It makes me wonder if the already elevated mg precipitated onto pumps/heater etc. due to either calcium or alk being in the “goldilocks” zone for it to happen and then was released when those parameters shifted, causing mg to further skyrocket. A reef chemist would probably know that answer.
have you every found why your magnesium is raising ?, I have the same problem , I can see it on my trident , everyday is going up about 20
Like I said it’s going up everyday , testing with my Neptune trident and Salifert , I did turn of my calcium reactor and now I’m dosing alk(baking soda ) and calcium and still the same , magnesium is going upIt is testing error if you added nothing and salinity is stable. Magnesium does not simply rise. Note that the salinity rise for a 20 ppm rise in magnesium is not detectable with a hobby refractometer.
I did sent my water to Triton lab and magnesium was 1660 , I did a lot if water changes with regular red seA salt it’s got lowIt is testing error if you added nothing and salinity is stable. Magnesium does not simply rise. Note that the salinity rise for a 20 ppm rise in magnesium is not detectable with a hobby refractometer.
Then something doesnt make sense - if its really going up '20/day' that means that 20 days ago it would have been 1260. Now there is no doubt that it 'is high'. Are you absolutely sure that you aren't dosing something with Mg in It? Are you sure that your salt was well mixed - i.e. the 'dry salt' ? Before you added it to water - and that the 'salt water' istelf was well mixed. ? Seems like there has to be another causeI did sent my water to Triton lab and magnesium was 1660 , I did a lot if water changes with regular red seA salt it’s got low
Magnesium about 1250 , so I drop it down to 1440 and since that time it’s going up and up
Like I said it’s going up everyday , testing with my Neptune trident and Salifert , I did turn of my calcium reactor and now I’m dosing alk(baking soda ) and calcium and still the same , magnesium is going up
Salinity is steady 1.025 All the time , I’m using brs calcium chloride. Maybe that’s gonna help , couple mounts ago maybe a year ago I’ve got a problem to raise the magnesium , I add to my calcium reactor two packs of remag media and I still needs to add liquid magnesium to raise it up , now my calcium reactor is turned off , I’m dosing nowI know, but it cannot ever rise on its own, so there is some source or salinity is rising.
How much total rise?
what exact calcium product?
what about salinity?
