i definately appreciate the advice... this is the one and only reason i would consider using a calcium reactor or dosing pumps... however, i did get some BRS dosing pumps earlier in the year, and decided to no longer use them as i was worried about a malfunciton with the timer and over dose something, especially alkalinity... my one and only concern with my system now, is the 1 point to 1.5 point alk swing when i do dose... i normally try to dose half in the morning and the other half in the evening, as i believe this helps the sudden swing issue...
but again, your idea with keeping the resorvior at a minimum, is a great idea that would alleviate my worries in that respect... however, it would also "un-simplify" things a little bit more... this calcium and alk thing, is the ONLY thing that i am at a cross roads with in my system...and i will admit, as i go along and my corals get bogger and more populated, this is one aspect i am going to have to address...
Yea, I understand. Here is a little information from a chemist/reefer friend (NOT me).
"Alkalinity levels drop quickly in a tank that's actively growing. Nominally, 1 meq/l (or 2.8 dKH) is consumed for every 20 ppm calcium consumed in the formation of calcium carbonate skeletons."
Here's a quick chart balancing calcium and alkalinity:
Ca (ppm) Alk (dkH)
400 6
410 7
417 8
425 9
432 10
My point is a 1-1.1/2 swing in ALK is a pretty big swing. You want to minimize this as much as possible. Calc is slow to change but Alk swings are very bad for sps tanks ime.
I may have missed it reading through, but what do you dose for magnesium and what level do you try to maintain?
Looking forward to follow your thread.
