EI and PPS

they are the same thing right? other than the amount of ferts that you add?

i found a great deal on theplantguy.com

they have a PPS fert package for 15$ with free shipping

while EI package is 30$ with shipping and taxes its 50$

I was planning on EI but Ive changes my mind to PPS

i did some reserch and they say theyre the same.

i want to get some of your input on these two types of fert methods

since im just starting

thanks!

Hi squatingdog,

PPS Pro dosing requires substantially less nutrients per dose, therefore the quantities of the nutrients provided is substantially less in PPS package he is offering than in the EI package.....just look at the size and number of the bags in the pictures. The PPS package only makes 2 liters of mix....not very much.

I have used both methods of dosing. When I first started planted tanks I did PPS-Pro but I was constantly dealing with nutrient deficiencies. I have used EI dosing for about the last four years; it is a much better method for growing healthy plants.

First, you can check what is listed on each to determine if they are she same nutrients.
Then check out the quantity you will get/w each.
Then check to see of any other equipment comes/w it.
Did you check the quantity/prices on this link ?

The shortest distance between any two points is a straight line...in the opposite direction...

Understanding the dosing concentrations differ (EI higher), can a member comment on the difference in required water changes?

Not trying to divert from the OP's question, but if you have a very large tank (180g), and want to use 'treated aged' water for water changes and have limited capacities for storage, would you favor one method over the other?

pps/ei

I have been using pps pro for over a year now with minimal to no difficiencies . check out GLA website for EI and pps ferts and procedures. Way less water changes with pps. Large weekly water changes with EI. I orderd my pps ferts from GLA almost a year ago and I still have some. They are both good if done right.

EI and PPS

I also use the PPS-Pro but only for 2 months. I choose the PPS -Pro because I can only change 64 gallons of water at one time . My tank is a 125 gal + a 30 gal refugium and a FX6 canister filter. My substrate is Eco complete 5" in the back down to 3" in the front with a 1" cap of very small natural gravel. So maybe I'm using about a 145 gals. That was one reason I chose the PPS Pro. I know when I am able to change a larger amount of water I will switch to the EI method.
