Every 1000 mg of calcium ascorbate will increase calcium in 90 gal of system water by less than 1/3 of a ppm. Only about 10% of the amount added of calcium ascorbate is actually calcium or around 100 milligrams for each 1000 mg. that is 1 ppm in 100 liters or 1 ppm in 25 gallons or 1/4 ppm in 100 gallons.<a href=showthread.php?s=&postid=11649322#post11649322 target=_blank>Originally posted</a> by madadi
regardless if the magnesium levels hint that calcium ascorbate is OK to use, i would prefer to use sodium ascorbate. if my calcium levels are already at ideal levels, how much vitamin C i can add would be limited because i don't want calcium to be raised even further.
sodium ascorbate and calcium chloride is a nice combination because its ionic balance (Na+, Cl-). salinity will rise but not enough to be noticed if your doing biweekly water changes where you adjust the salinity accordingly.

Same here. Now that I've got some buffer, I'm upping the dose.

Guess I should have ordered that instead but how much salt could really be in there?
As far as my pH, it's OK now that I added the Kent buffer, but my alk is now 15. I'm going to do a WC & stop adding the C, until I get the bufffered one.
Can you guys test for nitrates before during and after the treatment?<a href=showthread.php?s=&postid=11656250#post11656250 target=_blank>Originally posted</a> by cr8signs
Been dosing for 2 weeks now. Only 1000mg per day, 100 gal tank. All softies look good except 1 rock of hairy mushrooms are bleaching, but other hairy mushrooms that were struggling, are growing and showing better color. ONE BIG DIFFERENCE, all my algae is dying. Hair, bubble, bryopsis,(not sure if that is it) nasty stuff is going fast. What I think it is, my vit c tablets are from walgreens and they have magnesium stearate in them. My mag is now 1600. I don't want that any higher so I will have to get some pure vit c. and dose with the old when I need to raise mag.
No; calcium ascorbate does not contain calcium carbonate and as I mentioned before the amount of calcium ion it provides is neglegible (1000 mg will increase 50 gallons by only 1/2 of a ppm).<a href=showthread.php?s=&postid=11657378#post11657378 target=_blank>Originally posted</a> by Myrddraal
Is it possible that the Ca Carbonate caused my Alk to crash?
