Why is there copper in csm+B?????

I just received my ferts from greg watson.com and noticed there is copper in it???? why on earth would they put copper in this mix. It's bad for shrimp, snails some plants and I'm guessing fish too. Anyone have an idea on this?

90 gallon planted rainbow fish/ community tank, pressurized C02, 2.8 wpg cf, eco-complete,

1-20 gallon breeding/growout
2-15 gallon breeding/growout
4-10 gallon breeding/growout

currently breeding hi fin red eye swordtails, kribensis, orange platys, trying others
DIY central sump filter w/auto water changing and auto water top off, DIY in-line co2 reactor.

Copper is an essential trace element. That said, CSM is formulated as a hydroponic TE mix and is not sold for use in aquariums.

You can switch to Seachem Flourish or the new TE product from Tropica, both of which have lower Cu concentration and are higher in Fe than CSM.

This is from another post on APC about plantex and copper

Quote:
I can tell you that I have done heavy plantex dosing in my tank with cherry shrimp and their population was out of control until I added tetras (which ate the babies).

By heavy dosing, I had a solution made up of 3tbs/500mL and dosed at 1mL/5g

lets work this out
If I remember correctly 1tbs plantex=15grams, so...

3tbs/500mL= (3*15)/500=45g/500mL= 45000mg/0.5L=90,000ppm plantex
Plantex=0.1% Cu so the solution is 90ppm copper

5gallons=~19L=19000mL

So dosing 1mL of my solution into 5g it will result in ~ 5ppb copper

...assuming I did didn't make a stupid mistake LOL.

CMS has it for the same reason plants have it, it's required for growth.

Caffine is deadly...........at the higher levels, so is copper for that matter, but you still need it.

The dose makes a poison, not the addition of the chemical compound by itself.

Like any drug, too much kills the patient, not enough have no effect.

If you want Plantex CSM with a lower copper content the company will be more than happy to mix up a batch for you. I called and asked about the possibility of getting it made with much lower copper content and more iron. No problem. I just needed to order something in the range of 950 lbs.

One problem is the cash. I'm a little light right now. Cost delivered was going to be around $4000.
