High magnesium effects

[Reefermadness]

Ive been having some issues lately I had not tested but performed big waterchanges just to try to get my unknown problem under control
I performed a series of 50% waterchanges using Red Sea Coral Pro and was noticing a very high amount of white material on my bucket and powerhead with this new batch I bought
Mainly wondering what all this build up may be due to. Figured it was precipitation of calcium but not too sure..
tested my aquarium minutes after a waterchange to find these results

Ph 7.8
Alk 3.5
Mag 1520
Calc 410
Salinity 1.026

Anyone have any input as to what may be going on? I dose Salifert all in one 3x a week. Weekly 25-50% waterchanges. 14g Biocube
of course I should also test a fresh mix of salt. That will be done tomorrow

Sounds like you may have a bad batch of salt. If say first thing to do for now would be to mix up maybe 1/8-1/4 teaspoon of baking soda in a cup or container of tank water & put in high flow area in your tank our sump if you have one. This will help to raise your alk & ph & help to get it up & more balanced with your high ca & mag levels. You wasn't to go very slow with this though because changing the alk/ph too much too fast will cause shock to your livestock. You can do this every day until you can get your alk raised to whea more optimum level. You've got to get your all raised though asap. Just don't forget... Do it very slowly! Test before & after to see how much it changes, & mix in cup well before porting in tank. Good luck.

I Have the same thing happen to me with some batches of Red Sea Coral Pro and its even worse with aquavitro. I talked to someone at the MAX show from Aquavitro and he said its do to the high level of nutrients in the salt mix but putting the water in a little cloudy (as long as the salt has mixed properly) should be fine and will clear up in a bit (it does clear up in about 30-40 min). He also said you cant use a sponge or something to rub on the side of the bucket to get the white film off and back in the water would be ok. I've done that and its worked fine (even though some have said not to). My ph is 8.2-8.3 alk 7-8 mag 1300-1400 and no damage or signs of stress on the corals of fish when i do that (just add the water slowly and in a high flow area).
