The BRS reef chemistry testing kit has been 'rejuvenated'. I will be bringing it to this meeting and I will be there to test the tank water of BRS members. The cost (Payable directly to the BRS) will be $2 for specific gravity (salinity) and alkalinity (both tests for $2). $4 for calcium, magnesium, and phosphate (all 3). $5 gets you the 'works'. Minimum sample size is 250 ml (about a cup). DO NOT skimp on the volume or some tests might not be able to be performed. Make sure the sample goes into a CLEAN container or your results (particularly phosphate) may be meaningless. I recommend using only a clean zip loc bag.
I will attempt to test the samples at the meeting, but might run out of time as some of these tests take a considerable amount of time to get accurate results. If so, I will send you your data by PM within the next 24 hours on the forum provided you clearly write your username on your sample container.
I will be there from 12-3 PM. Please get your sample in as early as possible to facilitate the testing.
Details on the BRS testing methods:
The phosphate test is the low range spectrophotometric method (Hanna meter, good down to 0.03 ppm). The specific gravity is with an accurately calibrated refractometer. The calcium and magnesium are using the modified HACH test kit compared with a lab prepared standard. The alkalinity is using a titration with 100 mM acid to pH 4.2 using a calibrated pH probe/meter (the definition of alkalinity).
