ICP Test Results

[aedds2]

Just got my results back on RODI and Salt testing from ICP. Basing this off what "ICP Suggested Reef Tank" is I'm a little confused on the results. What should I change?

Side note: some LPS does not do well in this tank. Using Fritz red box salt.

	RODI	Salt Water
Aluminum	0.01	0.16
Boron	5.29	6.72
Barium	0.05	0.01
Calcium	435.36	466.25
Chlorine	18397.19	19110.73
Iodine	0.02	0.04
Potassium	375.83	435.36
Lithium	0.02	0.09
Magnesium	1259.8	1361.58
Sodium	9987.92	10572.47
Phosphorus	0.05	0.93
Rubidium	0	0.06
Sulfur	925.45	858.76
Selenium	0.01	0.01
Silicon	0.39	0.25
Strontium	8.2	11.92
Uranium	0.01	0.01

Values that both had a 0 in the columns were removed to shorten the spreadsheet down.

Chlorine stands out right away, along with some others.
How old is the carbon & membrane?

Def need to change membrane out. Carbon was just changed last month.

And what else stands out to you other then the chlorine?

A lot. When I looked @ mine most RO values were -0-.

If you were to send water samples to three different ICP vendors, you would receive three different sets of results. Which one would be closest to reality? No one knows.

Which vendors provide evidence about how close to realty their results are? Exactly none.

Did you know that using a Hanna Checker ito measure PO4 is more accurate than the result obtained from ICP measurements?

Not convinced ICP measurements are going to help you very much.
