How do you know you need to add the "essential elements"? Are you testing
for them?
I could ask you the same question about your soft coral toxins couldn't I?
If you are doing partial water to dilute toxins, how do you know they are
present if you can't test for them as you stated?
Is this addition *really* essential? :-)
Or is "essential elements" just a way to make more money? :-)
To answer the above questions: Don't get sucked into the hype.
