Water Parameters

[Rambo64]

My LFS came back to me with these numbers for a water test they did for me and I question their results

Ammonia 0
Nitrites 0
Nitrates 10
PH 8.2
Iodine .01
Alkalinity 3.0
salinity 1.020
Phosphate .1
Ca 420

They told me that my Iodine was low and that my alkalinity was solid. They also told me that my calcium was a hair low. Do you guys agree with their assessment? The Alkalinity number does not appear right to me unless they are testing with different units. Thanks for any help

Alk I assume is in meg/l so 3 meg/l is good. 420 Ca is fine as well. As long as it's not allowed to dip below 380 ppm and kept fairly stable, 420 won't be an issue. Here is an article(s) about iodine that may shed some light on it- http://advancedaquarist.com/issues/mar2003/chem.htm

Thanks for posting that article on iodine. I was wanting to know a bit more about it too!!
