I would personally not use it. It seems too high in boron, manganese, Zinc and copper for a planted tank. Below is a comparison of Plantex and Rexolin. Plantex has been widely used without problems. Rexolin? Never heard of it. Copper levels greater than 0.03 ppm have been shown to cause issues with sensitive creatures such as shrimp.

Code:
Plantex CSM +B

B		0.0613
Cu		0.0069
dGH		0.0896
Fe		0.5
Mg		0.1072
Mn		0.1432
Mo		0.0038
Zn		0.0283


Rexolin CXK

B		0.2206
Cu		0.0735
Fe		0.5
Mg		0.1765
Mn		0.4706
Mo		0.0074
Zn		0.6176

Thanks for ur reply!
Following is written on the pack :

Zn 4.2%
Fe 3.4%
Mn 3.2%
B 1.5%
Mg 1.2%
Cu 0.5%
Mo 0.05%

Those numbers are consistent with the results Zorofox got, at least in terms of ratio...

It seems really strange that there's almost half as much boron as iron... that doesn't really reflect any plant usage ratio I'm aware of and boron can be quite toxic to plant life in all but trace amounts. Maybe it is designed for use on soil that is already high in iron???

The numbers I listed were an average single EI dose comparison.

The actual fertilizer percentages are this...


Code:
Plantex CSM +B		Rexolin CXK

Fe 6.53%		Fe 3.4%
Mn 1.87%		Mn 3.2%		
Cu 0.09%		Cu 0.5%
Mg 1.4%			Mg 1.2%
Zn 0.37%		Zn 4.2%
Mo 0.05%		Mo 0.05%
B  0.8%			B  1.5%
Still far too much Zinc, Manganese and especially Copper for a Planted tank IMO.

Thanks!
Then I thing I should stay safe and should avoid this.
May be I will use it on my garden soil then.

Can I start EI dosing in my tank ?
My tank is low tech and without CO2.
Problem is I can't afford any water test kit and weight machine to measure chemicals.
What are the min chemicals required to start EI dosing ?
How to calculate amount of dosing ?
Water using in tank is hard water.
Recently facing thread algae problem.
Light on for 2x2 hours per day 36Watt PLL.
30% weekly water change.

Thanks for the link.

I have chosen EI low light/weekly but what shout I chose for "Round to digits past the decimal" ?
I'm going to 1000ml solution.
Can I use mineral water instead of distilled water ?
Most important which chemical are most essential for my low tech tank ?
There are lots of option at that page to chose like KNO3,EDTA Fe 13%,KCl etc.

The "core" fertilizers are kno3, kh2po4, k2so4, and micros (csm+b typically although some use microplex)

K2so4 and a micro mix are important for pretty much all planted tanks. Depending on you plant/fish ratio you may or may not need kno3 and kh2po4. Fish waste provides nitrate and phosphate, so the more fish you have, and the fewer plants you have, the less you'll need. High tech tanks always need these two, but some low tech tanks with heavy fish stock can do without. If you need lots of these two, then k2so4 becomes less important, and some high tech tanks use enough kno4 that they don't need k2so4.

Beyond these, some tanks need a gh booster to provide calcium/magnesium, but this is more for folks with very soft water or using rodi.

A few folks find they need a separate iron fertilizer. Csm+b has edta iron in it, which works well in most water, but high carbonate water will tend to precipitate it. Thus some hardwater folks add dpta fe, which is harder for plants to absorb, but more stable in hard, alkaline water.

Thanks for ur reply!

I guess I more fish but more plants too.
Water is hard and water left a stains on glass.
So I guess I don't need to worry about calcium/magnesium.

So,far my dosing calcukation as follows for 60lit/15gal low tech tank.

1.K2SO4 250gm + 1000ml water
2.KNO3 200gm + 1000ml water
3.KH2Po4 50gm + 1000ml water

I will dose each of 5ml of mixture once in a week.
But,problem is csm+b is not available here so I have find alternative for that.

Bump: One more thing.
Sorry may be off-topic question.
I read that for low tech tank changing water may cause algae due to change of CO2 level.
But,if I don't change water then there will be too much of ammonia due to to excess bio-load or fishes.
So,is there any way(plant) which can help to reduce ammonia from aquarium water ?
Then I don't have to change water weekly.

Check for milllers microplex. It may be available where csm is not, since it is a product of the UK instead of the US.

Facing Brown Dust(diatoms) algae problem my old tank.
Water become cloudy.
Tried to black out but did not work.
WC many times but did not work.
Feeding fish very less amount but not working either.
The Brown dust covers all the plants including substrate all over the tank.
Its also looks like mud in water.
But,how can much/soil come up all of a sudden from below.
My Hard Water may be cause of this but I got no option to use other water.



Keeping the following Trumpet Snails can be useful in this case ?
