Is that your tank water?

Silica (SiO2-3) 0.7 High

wow! that is the lowest i seen. What is your ro/di setup?

[B]Silica (SiO2-3) 0.7 High

Totally agree, don't be worried about that. Mine was 5.8!

Which salt or NSW are you using?
What's your w/c?

I'll bet that AWT have changed their Si measuring scheme somehow due to the many complaints, maybe a new probe or something.

You might just want to adjust the Mg up a tad, but you have awesome results, congratulations!

Your boron was super low as was mine. I've used Kent salt for some time with decently frequent water changes, but am trying out Tropic Marin Pro now. I purchased a Sailfert test kit to verify the results and supplemented with "Borax" (you probably can get it at your local Target) which is available in the laundry section.

I really like to know how his is sooo low compared to everyone else.

DrBegalke post your secret!! :D

Hey USC-fan...
Yes, that is water from my NC 12g. I use two units of Chemipure Elite (with GFO) on that system... maybe that is why the silcia is relatively low?

I try to do a 2-2.5g water change once a month, but sometimes it goes longer...

I use a mix of IO/oceanic, grocery store and/or LFS supplied RO and/or DI water.

What I don't understand is the B and Mo levels?

and BTW, I am excited that Ohio State plays USC in 2008 and 2009!

and also, I adjusted the Iodine (I¯)... should be fine next time around.

The elevated Mo is coming from your salt mix. Most synthetic salts have a little higher Mo than NSW. Not a concern IMO.

The Boron issue might well be explained better in one of Randy's older articles.

Boron in a Reef Tank

Ya, I have read Randy's article... what's strange is that I use two-part to adjust Ca/alk, so I would think that would replace boron.

I am not very concerned with it though, since all my livestock is doing great...

You know what Doc.

You hit the nail on the head (so to speak)

I always say...... if it looks good........ It is good. :)

Time to drop this remark again :)

AWT gives Mo as .01 ppm and that is NSW by most sources. I see they changed that after my e-mail that they where off a decimal as they use to give it as .10 ppm. Mo Most seasalts have nowhere near that.

past values thye gave

[b]Molybdenum (Mo)
Natural Seawater Value: 0.100 mg/l
Acceptable Range: 0.080 to 0.120 mg/l
Tested: 0.311 mg/l[/b]

All salt studies over the last few years show them to be around .001ppm . What I'm saying is the numbers that you guys are getting from them are wrong, just like their silica and PO4 numbers are wrong. There is no way, IMHO, someone has .3 ppm Mo unless they are adding it. That is 30 x NSW. You may get it you have crap loads of algae dying off and then their is the GAC, which most use, that sucks up Mo like a sponge :)

They give NSW silica as 0.040 mg/L, sorry it is way higher than that , @ 3 ppm in NSW. Yon only get that 0.04 or so where their have been massive diatoms blooms as they suck all the silica out ot the water. We ask to try not to let it get higher than 1 ppm for diatoms sake. Most salt test out to around 0 .5 - 1.5 ppm or so.

I would not worry about Mo anymore than one should worry about Iodine or Boron or even potassium and in most cases silica. :)

I have sent them crap loads of info and data to back me up and as to the why's. They are bringing in an outside source to re-look at their testing procedures. As I told them, seawater is NOT FW and you have to know what you are doing as the salt in seawater interferes with many test. I think once they get everything in order it will be great service. They are working at it hard. They just need some more time.

that is really good news!!!

I really like the service but i hate having so much doubt about the results.

Well overall I think most of their tests are good. There are just a few variables in specific tests that need to be refined.

I agree Eric. Most of the tests are worthwhile. Some should not be tested at all. It only confuses the aquarist.

I am happy with their service so far... it's good to see they are making some changes. :)

...come to think of it, the water I have been using lately is 2.5 g jugs of distilled water from the grocery store... not sure if that makes a difference or not...

AWT and PO4 numbers are wrong. [/B][/QUOTE]

Boomer, are you stating that their results are wrong for PO4 or that there suggested values, or decimals, or all?

Would you tell me if they state my phosphate (3 tests) is Tested: 0.040 mg/l, Tested: 0.061 mg/l, and then last month it's Tested Phosphate (PO4) 0.13 Good is that totally wrong? It matches my Merk kit pretty much.

Thanks,
Ralph

It looks like the test value you guys for PO4 is off and they are working on it. Meaning, your PO4 is lower than what they state for your water. Same for Molybdenum.

Well that's good news! (not really, but you know what I mean!)

So, should I correct the boron or not?

I would say no, but read Randys article on Boron in the Reef Tank and decide for yourself. :)

is mg/ml the same as ppm? they measure in mg/ml

I haven't seen mg/ml and no that is not the same as ppm.

mg/l is very close to ppm and for our purpose is samo samo.

Doc, I question the boron results in your results. I find it hard to believe it is that low. It would be interesting to know how they tested for that.
