Alkalinity High Calcium Low

[marie]

The alk, while high, it isn't too high nor is the calcium that low but if you want to balance them a bit more just add the calcium part (of the 2 part additive) for a few days until the alk drops a bit. 10 dkh is probably a good figure to shoot for

here's a very good calculator to tell you how much calcium media to add to ballance your alk/calcium. from experience, it's fairly acurate. and it has a nifty little chart for us visually minded people

I think that Holmes-Farley would probably suggest that this is just the result of overdosing both parts. Cut back on your dosing quantity, but continue to dose both parts. I think you will find the Alk falls, while the Ca doesn't move much.

You could try to manipulate the Ca/Alk separately, but I doubt that you need to in this case.

you levels are very good actualy. higher Ca levels than 380 will actualy start to slow down coral growth. I used to keep my tank at 380ca and 13 to 14alk and had the best results for both color and growth.
