test results-what do you think?

[btodd43]

:roll: Heres my test results see what you guys think:

No fish in tank- temp-78
salinity-1.022-1.023
calcium-415
alk-4.6 meg/l
iodide-.02 or under
mag-1300
ph-8.1
thanks for your input.....

Looks like your on the right track. Nothing looks out of whack to me. YOU COULD bump CA up a bit to 480 or so... but if nothings in there to use it I wouldn't even worry about it.

:? Yea I am not using the a+b yet because the alk is a little high-just doing purple up to suppliment the corals and bring up the calcium to 450-480 and then I'll start using the a+b -If I use kent cal concentrate it gos up real fast...

I've had GREAT results with B-Ionic 2 part additive.... it takes care of your AlK and CA in one fatal swoop Just somthing to consider.

IMO your readings are fine - if anything your SG is a bit on the low side for a reef. IMO there's no reason to maintain anything other than natural seawater parameters in our reef tanks.

FWIW, here are the parameters of some water samples I took from a wild reef in the Caribbean. I repeated the tests several times on several samples and they were very consistent:

Ca = 410 PPM (Salifert)
Alk = 7.2 dKH (Salifert)
SG = 1.026 (refractometer)
pH = 8.27 (calibrated handheld pH meter)
Temp = 80 degrees F (calibrated handheld meter)

Out of curiousity I also tested for Ammonia, Nitrite, Nitrate and Phosphate with Salifert kits and, as expected, could get no detectable readings.
