purple up enough for calcium?

[ShrimSkin]

On the bottle of Purple up I think it tells you to maintain calcium levels to a particlar number which I do not recall. But as stated above you wanna be over 400, I think going with a calcium supplement is a good idea. I just switeched to Tailored Aquatics Calcium and DKH and so far I am very pleased with the results. I do also add Purple Up on the days I dose calcium and its been working real well for coraline and my SPS.

A Ca of 380ppm is on the low side but wouldn't say unacceptable.

i agree 380 is a bit on the lower side i'm slowly bringing it up to the 400's, mark the reason i started thinking about changing is i'm finding that it's hard to get it too the mid 400's without it falling quickly back down to the 380's, is this because of my alkalinity level? (8 dkH )

It could be because of Alkalinity or Magnesium. Can you tell us your readings for everything that you test for?

calcium is now 380 and magnesium under 1100 last time i checked

had problem before as well trying to get Ca with low Mg. It goes at about 3:1 ratio.

Is that all you test for? You don't test pH, Ammonia, Nitrite, Nitrate, Phosphate, Alkalinity, etc?

Your magnesium should be around 1350. Think of Mg as the fulcrum on a teeter totter. You can't keep alkalinity and calcium up if your magnesium is very low. In your case, it is very low. Try to aim for Calcium 400-430, Alk 8-10, Mg 1350-1400. pH should be 8.0-8.4, and Am, nitrite, nitrate, and phos all 0. Not close to zero, but AT zero.

I am testing for all of these too. As some others have reported there was a batch of Kent that had some weird parameters. Calcium is continuously high, while Mg is low. So I have recently been dosing to get the Mg up.

My Alk has been too low. So before dosing for alk I think I am going to hold off on the purple for a few weeks to see what happens.

no no i test for all those, just thought i'd point out the important ones first..

pH 8.3 ; ammonia undetectable ; nitrite 0.25 ; nitrate 0 ; alkalinity as mentioned 8 dKH ; phosphate 0

i'll start dosing some form of magnesium in that case, think kent tech-m will do it, i've been relying on my salt mix (seachem reef salt) as a constant source for magnesium!
