"Curious about calcium" survey
 

I didn't make this a poll because it wouldn't provide all of the info I wanted, please treat it as a survey.

Please give a general tank description and what you are using for Calcium/alk suppliments?

ie: 100 gallon mixed reef, calcium reacter, 400ppm and 8dkh etc...

Thanks everyone! :biggrin:

90 gallon mixed reef. Tech CBA Ca/alk. ~370 ppm. ~10.5 dKH.

40 Gallon mixed reef
Liquid Reactor

130 gallon reef - 390-400ppm ca
kalk reactor
occassionaly add Kent turbo calcium to boost ca level up when low

180G mixed reef, calcium reactor, 430ppm and 9dkh, Kalk drip (soon to be a Kalk Reactor) sometimes use calcium if needed to boost levels up if there has been any new additions.

65 gallon mixed (90% LPS) reef.
Ca floats around 420 ppm - when it hits 400 I nudge it up to 450-460 over a few hours.
Alk sits around ... I think 9dkh? I'm drawing a blank. Anyways, I park it right in the middle of "normal" seawater.


My alk supplement is just Arm and Hammer baking soda. I don't consume too much so I'm not worried about pH drop as soem folks seem to be.

My ca supplement is a Calcium Hardness increaser from the pool supply store. It's a 77% calcium chloride, essentially the same as Dowflake or Turbocalcium.

I test with Salifert tests a couple times a week, maybe even less than that now that I've more or less mapped the system's consumption.

75g, mostly lps and sps, kalk spiked with vinegar and kents 2 part. Calcium 380 and alk 8dkh

~75G water volume SPS only tank, Calcium - ~400ppm, Alk - ~3.20mEq/L, Calcium reactor and Kalk reactor.

Calcium Reactor used and Kalkwasser mixed with all top-off water.

Calcium is 420 and Alkalinity is 9dkh.

120g SPS tank.

72 gallon, Kent Liquid Reactor, Ca 425 ppm, Alk 3.5 meq
