i have a 60g marine aqaurium with a 30g refugium pc lighting.i've switched from using the liquid calcium to the dry turbo calcium, i mix it in a cup of ro
water before adding it to the sump.i cannot seem to keep my levels
up where they shuold be. my kh is about 12dkh. any ideas or advise would
be greatly appreciated.

What is your current CA levels?

[dr reefinski]

335ppm ,adding 3/4tsp of turbo calcium raises level about 10 ppm,can or should i be adding more than that?

12dkh is awfully high. You want to have kh around 8-9 in a reef tank. This is probably why you can't keep your CA levels up. I haven't used the dry turbo calcium though, I use the liquid type.

You really need to checkout the Mg levels first as if this is too low you won't stand a chance of getting the Ca/Alk levels correct. Mg needs to be around 1400ppm, When you've got this balanced then start correcting you ca/alk but remeber don't try and do this to fast! Any of them.
When your mag levels are ok you can then try and use a two part buffer called c-balance.This is a good simple method and it's also clearly marked on the box how much you need to add to buff up to the right levels

i will check my mg levels,that is something i have never been privy to.
i have been doing this for a couple of years and i have probably learned
more in the last few months than the entire 20 months prior.thank you guys
for the support.this site is already great!

I dont know why Ryan doesnt have these posted somewhere for everybody.

Check out you system with these.

Keep in mind anytime you change something in your tank (especially water chemistry) it needs to be watched closely. It may say Ca on the label butthat doesnt mean your tank we react the same as it has been with a different type or brand. Good luck!!!

I'll ask the simplest question first. Why did you change what you were doing? Were your CA levels always low?
