Calcium and Clams

[jumpfrog]

I'm researching to add a clam to my reef tank. 125 with approx 850 watts of mh and pc.
How much affect should 1 clam have on my calc consumption rates? The rest of the tank has lps and softies. Right now I dose 2 part to maintain alk and calc. Able to keep steady at 11-12dkh and 460-480 calc.
I don't have an interest of going full scale sps or adding any reactor or dripping. That's why I'm looking for a little feedback on the clam.
Thanks

you should be fine with one clam you might have to up your dosage though just test for a while to see if u need to up your dosage or not
i have 2 crocea clams in my 100 with about 8 other pieces of sps some lps and softies and i dose b-ionic 30ml a day of each my alk doesnt get above 8.6-9 and my calcium is at 420
