This should be interesting. I sent water samples to be tested professionally by AWT. Sometime next week, I should get results back on the following params, which I'll record here later:
For comparison purposes my own test returned the following results at a density of 34.5 and salinity of 1.025.5:
- Ammonia: (API) Undedectable
- Nitrite: (API) Undedectable
- Nitrate: (API) Undedectable
- Phosphate : (API) Undedectable
- Silica
- Alkalinity: (API) 8dKH
- Calcium: (API) 460ppm
- Potassium
- Magnesium:* (Elos Kit #1 w/ 100 per drop) 1300ppm; (Elos Kit #2 w/ 75 per drop) 1350ppm
- Strontium
- Molybdenum
- Iodine
- Copper
- Boron
My results from AWT are in!
Water Test Summary
Ammonia (NH3-4) ........................Good ......................................... 0.003
Nitrite (NO2)................................Good ......................................... 0.003
Nitrate (NO3)...............................Good .............................................0.5
Phosphate (PO4) ..........................Good ........................................... 0.11
Silica (SiO2-3) ............................. High..............................................1.2
Potassium (K) ...............................Low............................................. 260
Calcium (Ca).................................Low........................................ 256Boron .................................... High............................................ 12.4
Molybdenum (Mo)......................... High..............................................0.3
Strontium (Sr) .............................Good .............................................9.1
Magnesium (Mg) ..........................Good .......................................... 1163
Iodine (IŻ)...................................Good ........................................... 0.04
Copper (Cu++) ............................Good ........................................... 0.00
Alkalinity (meq/L).........................Good ........................................... 2.88
An important thing to note from these results are AWT's
LOW calcium readings compared to my
HIGH results @ 460ppm from the same water sample. This is what they say about Boron as related to calcium:
"Boron
Natural Seawater Value: 4.6 mg/L
Acceptable Range: 3.0 – 6.0 mg/L
Tested: 12.4 mg/L
(HIGH) Your boron level is too high. We recommend the suspension of any buffer
containing borate salts until levels stabilize. You may also wish to perform a partial water
change. Borate is an important part of the water buffering system, and it helps keep
calcium levels stable. An overabundance of borate can cause dangerous fluctuations in
alkalinity and pH, as well as causing
inaccurate calcium test readings."
Could this mean that due to my extremely high Boron levels, I've been getting erroneously high readings from my own API calcium tests? If so, could it cause it to be off by that much? AWT tested Ca at 256 mg/L, where NSW has a value of 400 mg/L. I tested at 460ppm, where NSW has a value of 380ppm. Weird.
Now I wonder, which of my additives contains high Boron? I've heard from someone on NR that SeaChem Reef Salt contains high boron. Hmmm. Can I get a little help?
