another calcium reactor question.

[geo*SanAnto]

why is the alk of my ca reactor so high?10 bpm/40 drops per minute of effluent-
Ca-675ppm
alk-45 dkh or something high like that
tank Ca.-350ppm
alk.-9dkh
ph.-8.3
temp- 80.0/80.8
sg/sal 33/34 - 1.024/1.025
50 gallons total
when i first started the ca reactor 2 weeks ago all was fine now its unbalanced.what should i do?any advice

whats the ph slow down the effluent and the ph will lower


or add more bubbles

thanks for responding chadfarmer ph of eff. is now @ 7.4 ,so lower ph =more dissolved media=higher calcium?should the alk be that high.
