Low Calcium... Kalk Doser?

Hey guys,
just recently, i have been having trouble getting my calcium up to good levels in my 75g. it hovers btw 250-300...
Every thing else is great (Nitrites, Ammo, Nitrates, PH)

I have been dosing extra calcium suppliment, but it never changes.

I read a few conflicting articles on WWM and on reefkeepers:

I think I might drip Kalk w/ a doser?

is this a good idea?
How much kalk do I use?
Do I drip it 24hrs? or just at night?
Or do i just mix it up in my top off water and not use a drip?

:thanks: Jarrod

I dose B-ionic every morning when ph is low..
works great for me
I don't have the best lights and I still get descent growth

What are your alkalinity and magnesium levels?
