dosing traces

Can anybody tell me how to calculate traces for a 20g tank. I was using a commercial brand, but I bought some bulk mix from a hydroponics store. I have chucks aquarium calculator, but I can't find anything about how to mix and dose the traces.
My bulk traces mix ingredients list is as follows;
Iron 7%
Maganese 2%
Zinc .4%
Copper .10%
Boron 1.3%
Molybdenum .06%

Any hints, please...
even if it's 'go back to the fish place and buy the prepared stuff'

What is the brand name of the trace mix you purchased?

It's from Homegrown Hydroponics (gotta love that name) #6 in their "six pack"

Rex I think he got the raw ferts from a hydroponics store.

I can't really comment on how to mix those up. Hydroponics and aquatic plants aren't the same thing...those traces might not be the right ratio for an aquatic system.
I only suggest Flourish for a trace (in high light tanks) or a solution of Plantex CSM+Boron.

It's probably Plantex CSM or close enough.

Mix one tablespoon of the trace in 500 ml of water and dose a couple ml a week and you should be fine.

Yet another coincidence. I was just doing a search on this topic, and I have the exact same #6 pack. My tank is a bit over 2x the size, so I can follow a similar regimen.

However, from other threads I've been noticing lately, it seems like folk dose traces every day or every other day. Is that a better approach than a couple of ml's at a water change?

I'm still trying to figure out why my NO3 doesn't drop much throughout the week, even though my tank is heavily planted and my growth is decent (...and maybe that's a good thing!). Just got my LaMotte 3110 test kit, so I can start doing some reliable NO3 tracking...

Well, visiting Rex's site yet again, I can always follow the following advice, "I also make up a solution of Plantex CSM using two tablespoons of Plantex mixed into 500 ml of water. Using this solution one should dose .5 ml three times a week in 20 gallons of water on a medium light tank." and just adjust it to my tank size.

Oh, and I bought this trace before I learned about Greg's site. I was planning on using it as if it were CSM+B. When (if?) I exhaust the supply, I'll go get the "regular" stuff.

Actually, this "six-pack" fert could be CSM+B.

Plain CSM:
Iron 7%
Manganese 2%
Magnesium 1.5%
Zinc .4%
Copper .10%
Molybdenum .05%
Boron 0.0%

Six-pack fert
Iron 7%
Manganese 2%
Zinc .4%
Copper .10%
Molybdenum .06%
Boron 1.3%

CSM+B:
Iron 6.53%
Manganese 1.87%
Magnesium 1.40%
Zinc .37%
Copper .09%
Molybdenum .05%
Boron 1.18%

If not it is almost identical. When they added the B which must be done in addition to plain CSM, it seems like they did correct the other percentages.

Hey thanks, all! And Rex for being the quickest reply ever! I will mix that up and go for it. I bought the Homegrown Hydroponics as it was available in Canada.
This forum is a treasure trove of information and helpful people.

Yes, most of us with high light tanks dose trace every day or every other day. I alternate between a little iron on one day, then trace the next...back and forth. I also dose potassium 2x a week, since I don't often have to dose KNO3...I don't want a K deficiency.
If you have a lot of fish, your NO3 levels might stay pretty stable - enough fish waste to meet the plants' demand for NO3.

This doesn't matter much, but at least good to know. Your six pack fert is Plant-Prod Micronutirent Mix. The percentages of the first post exactly match the percentages on this site (scroll down abit).
