Hi All,

I'm wondering if Seachem chart and EI are the same, and if they are different how close they are to one another?

I wish I found EI before I bought a complete line of Seachem. I'm doing 50% water change weekly, following Seachem chart for my 30 gallons heavily planted tank, but I cannot control staghorn.

Overdose 3x Excel for 14 days, without success.

Please help, any suggestion is appreciated.

here's my tank setup.

50 gallon tank (but only hold 30 gallons of water)
2.5 wpg
pressurized co2 at 20-30ppm
50 neon tetras
50 cherry shrimps
12 crystal red shrimps

Regards,
Kevin

Well I'm not sure if this is about money or starving plants.o_O

A standard, directions off the bottle dose of Seachem Nitrogen adds 1.07ppm of NO3 per dose(9ml?) twice per week in a 150G.:mad:
If you used a 64ml dose you would reach the EI target of 7.5ppm NO3, three times per week. Total of 192ml per week.
We could call that 200ml per week, this sounds costly!:eek:

If you purchased 1 pound of KNO3 @ $3 it would make almost 17-250ml bottles of Seachem Nitrogen.:cool:

There are calculators to solve all this, even one on this site.

Staghorn is poor co2 or dirty filter/low flow , you say you have 20-30 ppm of co2 but the difference is so big between 20 and 30 ppm .
By the way, how did you measure your co2 levels ?
