Sorry...here's the reply (maybe MBay could show this to his chem friend too):
"Why are so you adding L-Ascorbic Acid , sodium salt (Fw : 198.11) instead of using
L-Ascorbic acid ( Fw: 176.12 ) ? The L-Ascorbic acid (Fw:176.12 ) is available in a
99+ % ACS Purity with <0.002 % Heavy metals & < 0.002% Iron where as the
L-Ascorbic Acid, sodium salt is not available in even a 99 % purity level .
The L-Ascorbic Acid, sodium salt that you are using contains higher levels of
both Heavy Metals & Iron impurities. These heavy metals specifically lead may
be deposited in Invertebrates.
Next point : has one performing this test considered the effect upon the synthetic
salts trace elements ? Marine synthetic marine salt mixes use EDTA as a chelating
agent except for one specific brand , Marine Enterprises EPA Certified Bio Crystal.
Adding L-Ascorbic acid , sodium salt into aquaria containing EDTA chelated may further
reduce the availability of trace elements.
If the test participants are instead using natural seawater has anyone considered
the effect of adding these amounts of L-Ascorbic, sodium salt upon the Poly phosphate
& Tri Poly phosphate buffers ?
During the mid 1980's we were aware of attempts to use L-Ascorbic acid +
Methylene Blue ( in bare aquaria ) plus heavy aeration for cyanide caught fish .
Poly-Filter (r) was used in the aquaria after the cyanide - reversal attempt
and appeared to increase survival ratios.
As for our comment about using Poly-Filter (r) in this test, we wonder how
long the 5 milligram to 30 milligram doses of L-Ascorbic acid, sodium salt
actually remain viable : 15 minutes , 60 minutes when added to a highly
alkaline buffered reef aquaria. It would be somewhat similar to adding
very small amounts of HCL (Hydrochloric acid) or Sulphuric acid ( H2SO4)
into reef aquaria ! Using a pH meter you could see the mineral acids
neutralized within seconds. The organic acid would last longer but by
how much , a few minutes maybe one hour ? We don't believe this
small amount of organic acid (L-Ascorbic acid, sodium salt )would last long
enough in any reef aquaria , larger than 30 gallons , for a water pump to
pick up the traces to even pass through a Poly-Filter (r). Has anyone
spent the money to actually have a Independent Certified Research Lab test
the experimental reef aquaria water for residual L-Ascorbic acid, sodium salt
( in 5 - 30 mg. additions) after one hour ? Use a Independent Certified Research
Lab not someone associated with the experiment, or a friend of someone ,or
some company involved in the experiment.
