high ca why ???

[Hi_Bear_Bear]

my ca is always high at 550ppm , i using red sea test kit, previously using sera also the same.i using coralife sea salt change 10 percent every 2 weeks and kh at 7, still trying to bring it up with seachem reef builder. i intend to dose kalkwaser bring the kh up but will it cause ca and ph to shoot up also ? help.

I've heard that red-sea test kits tend to be generous at results.. maybe you could borrow from another to test/verify the kit.

If the kit shows verifies correct, stop using reef-builder and kalk, try something like baking soda to hold ur kh, as there is no Ca ions in baking soda. Ur calcium shd drop after a while(a week or so),... then test again

how about the dosage?

will it increase the kh or only maintain it.

Why bother bring it down?

Ppl want high no luck too.

Unless you dosed something that caused the high CA. If its the quality from your new salt water, better.

That depends on how much you dose. Did you check out the link I posted above... It tells you how you need, based on 3 inputs, your tank volumn and what the current level is and what the you require. Choose the alk part.

Can you please advise the brand of baking soda that can be used for alkalinity increase? Does anyone will do?
