Did they test the s.g. for you?

How do the amm/nitrite/nitrate compare with your own testing? It looks like your tank is cycling.

Still waiting on my results, but I'll post them when they come.

King-Kong · #3 10/24/2007, 10:57 AM

cd77: those results are freshly mixed; not tank water.

cd77 · #4 10/24/2007, 11:09 AM

D'oh! Maybe we should refrain from posting our independent (freshly mixed) results until we get the salt mix results back that Begalke and AWT have organized?

cd77 · #5 10/24/2007, 11:26 AM

And, (and just for kicks and grins, yes I understand the controversy behind this) Here is what the S-15 report got at an s.g. of 1.026 ~7 years ago. The biggest gripes in the S-15 report were that pH was dangerously high and that calcium was very low:

Phosphate (PO4) 0.55 (S-15: 0.006)
Potassium (K) 356 (S-15: 392)
Calcium (Ca) 434 (S-15: 310)
Boron (B) 4.4 (S-15: 4.28)
Molybdenum (Mo) 0.1 (S-15: 0.002)
Strontium (Sr) 8.8 (S-15: 10.24)
Magnesium (Mg) 1207 (S-15: 1310)
Copper (Cu++) 0.05 (S-15: 0.076)

Silica (SiO2-3) 4.5
(S-15: Silicate: 0.50)
Iodine (I¯) 0.02
(S-15: Iodide: 0.27)

Wow... I wonder what results you'd get if you sent in distilled water.

USC-fan · #8 10/29/2007, 07:36 PM

Wow those are strange result!

How did you set up the samples?

What kind of filters are you using for your ro/di?

I pulled the samples from my regular mixing tub after 24hrs...

60gpd Hi-Si membrane with 2 carbon prefilters and one 1 micron prefilter, outlet run through a Kent mixed bed DI filter.... all filters are brand new...

you might want to check out this thread on the Chemistry forum.

Have you tried contacting AWT about your results?

SuAsati · #11 10/29/2007, 09:13 PM

Thanks for the link, Not yet...

bmwaaron · #12 10/29/2007, 09:37 PM

Im sorry but could you name the company that you used?
maybe a link to there site would be nice

What salt were you using at approximately what s.g.? Any other additives besides Mg?

Along with others (including my own) your calcium tested higher with AWT than using home test kits, and your silica seems exaggerated. I wouldn't be alarmed.

Seeing other results though, I'm wondering why my Mo levels are so high and whether or not I need to be concerned.

I wonder if nitrate levels can naturally rise during shipping (?)

USC-fan · #16 10/30/2007, 08:31 PM

I'm going to get a spectrapure silica buster DI, your levels are A LOT lower than mine.

edit:here is my last month AWT test. I should be sending out another test next week.

Tank is 5 months old and using RC salt.

Ammonia (NH3-4) 0.010 mg/l
Nitrite (NO2) 0.005 mg/l
Nitrate (NO3) 0.40 mg/l
Phosphate (PO4) 0.220 mg/l

Since we're all posting our results to this thread:

Using half IO, half RC mixture. Original posting. s.g. at the time was around 1.025. At the time, tank was ~11 weeks young.

nauticac4 · #18 11/05/2007, 10:32 AM

Ammonia (NH3-4) 0.010 Good
Nitrite (NO2) 0.040 Good
Nitrate (NO3) 9.7 Good
Phosphate (PO4) 0.07 Good
Silica (SiO2-3) 1.2 High

Alkalinity (meq/L) 2.80 Good

My calcium test kit by API told me calcium was 380-400. I have slowly been raising the calcium. What can I do about the Silica, I am using a Ro/Di unit rated at 75GPD with a 0 TDS reading.

lactose · #19 11/09/2007, 10:11 AM

My results...

Ammonia (NH3-4) 0.004 Good
Nitrite (NO2) 0.004 Good
Nitrate (NO3) 0.5 Good
Phosphate (PO4) 0.14 Good
Silica (SiO2-3) 3.8 High
Potassium (K) 373 Good
Calcium (Ca) 382 Good
Boron (B) 2.1 Low
Molybdenum (Mo) 0.1 Good
Strontium (Sr) 7.8 Good
Magnesium (Mg) 1311 Good
Iodine (I¯) 0.02 Low
Copper (Cu++) 0.02 Good
Alkalinity (meq/L) 2.02 Low

I sent these in Monday morning and got my results Wednesday night so that is pretty good turn around.

Of course like everyone my silica was high but not sure that is real yet.

I feel good about just about everything there.

My phosphate on the merck kits always read 0 or one step up from that (don't recall the number that correlated to off the top of my head).

As for my Ca and Alk, the Alk seems in the range I have been testing (I have been planning on moving it up so hopefully future tests will reflect that). Ca appears to be lower than I was seeing with API, Seachem and Salifert kits so I am going to retest (I was seeing 440-460). And make sure I test the same 'sample' of water I send back next time to be able to compare with their results apples to apples next time.

Boomer · #20 11/17/2007, 01:50 PM

I explained all this to them via e-mail. They have some real issues here. Another issue may be Alk. The pH end-point for FW Alk is not the same for seawater Alk. Some test kits are based on FW Alk and can read 10 % to low. I have know clue if they know this or not. They are woking on it.

Yeah I use this salt and is pure crap.

Latest and probably the last for a while atleast.....

hw Marinemix freashly prepared sent 4 days after preparation.
=================================
Ammonia (NH3-4) 0.020 Good
Nitrite (NO2) 0.017 Good
Nitrate (NO3) 0.7 Good <----
Phosphate (PO4) 0.03 Good <----
Silica (SiO2-3) 0.9 High <----
Potassium (K) 289 Low
Calcium (Ca) 394 Good
Boron (B) 3.0 Good
Molybdenum (Mo) 0.3 High
Strontium (Sr) 8.4 Good
Magnesium (Mg) 1096 Low
Iodine (I¯) 0.06 Good
Copper (Cu++) 0.00 Good
Alkalinity (meq/L) 2.34 Low

===================================

I ran the prepared water at 1.023sg through Po4/Si remover in a canister filter for four days.... It was a new box of Hw Marinemix, that claims no PO4/Si or Nitrates.

reefkoi · #24 11/26/2007, 12:48 PM

Hmmm the salt manufacturer claims no phos or nitrate. But it tests as having them, Who do we believe? I don't know what to think here. Are the readings sporatic? I dunno, I am sending in my second submission today and will compare to the last months results.
Honestly I have to trust they are actually testing the water accurately, otherwise I have to spend more money and buy all my own test kits.
If I do that I won't be much better off though, as I can't read the charts well on most of them and I really don't have the patience.
It's interesting that everybodys silica is high, some 3x's higher than others, but then again that is possible.
Now can one of the Physisist/nuclear reactor/doctor/lab tech/MBA guys that are adamant with knowing the accuracy find another lab somewhere in the USA to send in a few samples to test against these results so we can move on?

Boomer · #25 11/26/2007, 01:32 PM

It's interesting that everybodys silica is high, some 3x's higher than others, but then again that is possible.

Care to explain that when pasts tests on almost all salt for Si are ND or less than .5 ppm. And when most run RO/DI and many with silica busters

Again, silica in NSW is ~3 ppm but we should keep it below ~1 ppm. Even Shimek's test done on IIRC 20 or so running reef tanks all showed below NSW. The where from 2 -80 % that of NSW. And how does Dr AWT result showing zero for NSW sound right

I'll tell you again, based on an e-mail from AWT they KNOW they have some issue with some levels. That is WHY they are L@@KING into it and bringing in a second outside source to check their procedures. You need to actually READ these posts on RC we have posted about AWT. You seem to miss allot

WE still want this AWT thing to work, owned by Aqua-Medica or not. As it does not cost one an arm and leg.

find another lab somewhere in the USA to send in a few samples to test against these results so we can move on

Sure Chris and are you going to pay for it

ENC labs
http://www.enclabs.com/index.htm

and we also found one in Washington state that wold do it for $8.00 / parameter. You seem not to know that some for these test can only be accurately done with ICP and not some probe or Spectrophotometer.
