Here is his thread: http://www.plantedtank.net/forums/sh...hlight=pps-pro
If you scroll down he offers a number of a la carte fertilizers, as well as blends including PPS-pro and EI. I bought the "EI Liquid Ferts"
"EI Liquid Ferts
Want to dose ferts but the cost of liquid ferts is too expensive???
Dont want to go through the hassle of mixing dry ferts yourself???
Then this is for YOU!!!!!!
What you get- 2x 500ml dosing bottles(1x Micros, 1x Macros)
2 complete refill packets( so you are essentially getting enough to make 1500ml of both micros and macros)
Cost- $28 shipped
It will be shipped without water, all you will need to do is add 500ml of RO water to each bottle. When the solution in each bottle runs out, simply add the refill packet to the appropriate dosing bottle and add 500ml of RO water and you are good to go again.
Add 5ml per 20 gallons of water for each the micro and macro 3x per week on alternating days per the EI dosing instructions.
How long will this last me??
20 Gallon tank- roughly 2 years
40 gallon tank- roughly 1 year
80 gallon tank- roughly 6 months
and so on...
Special thanks to WETS dosing calculator:
Warning: Micro solutions will sometimes grow mold, to prevent this you should either refrigerate it or add 10ml excel to the solution
Concentrations(as per wets calculator):
Fe 0.50 ppm
Mg 0.11 ppm
Mn 0.14 ppm
Mo 0.0038 ppm
Zn 0.03 ppm
my personal confusion aside, i recommend purchasing anything you might need from him, as many others have
