CSM+B Plantex Question

[JDogg]

first what is in CSM+B Plantex? what elements/nutrients (is it basically equivalent to flourish?
does anyone have an easy way to calculate how much 1 tsp of CSM+B Plantex will give me is ppm of each nutrient in a 75 gal tank? lets say i am aiming at dosing 3 days a week to reach a total of 0.3 ppm fe every week.

also according to greg watson's page it suggest also dosing Magnesium sulfate, why?

it is roughly equal to flourish, but it doesn't have any calcium I believe.

Magnesium sulfate is just epsom salt. I don't think you really need it unless you want to do some major tweaking or your traces.

Fe 6.53%
Mn 1.87%
Mg 1.40%
Zn 0.37%
Cu 0.09%
Mo 0.05%
B 1.18%

(is it basically equivalent to flourish?

Yes in that they're both used as trace mixes. (Flourish has macros too but not enough to be significant for calculations.) We use Fe ppm as an estimate for everything in trace mixes: the ratios between nutrients are pretty much the same.

1TBL of CSM+B into 250mLs is approximately the same as Seachem's Flourish.

Here you go. A decent dosing solution would be 5tsps of CSM+B into 250mLs, with 1tsp doses of this solution every other day for 0.1ppm Fe per dose. If you want to dose dry 1/8tsp slightly overshoots your target but should be fine. 1tsp CSM+B dry into 75gals is ~1.0ppm Fe.

I believe Zezmo may be adding CSM+B into his spreadsheet, which calculates everything. http://www.aquariumadvice.com/viewtopic.php?t=86655

Mg is an important nutrient, and often in low ppm with tap. The water company should be able to provide Mg ppm. If you have reasonable GH and do not suspect Mg deficiency you can skip it, or dose 5-10ppm Mg and observe.

thanks, very much the type of info i was looking for

If you have reasonable GH and do not suspect Mg deficiency you can skip it,

i have a very high GH, so i do not think Mg deficiency is a problem, what are the signs?
