Guide: Reaction POSs

You don't stand a chance
against my prayers
You don't stand a chance
against my love
They outlawed the Ghost Dance
but we shall live again,
we shall live again
Robbie Robertson - Ghost Dance

I intend to make this a basic guide to taking moons, and turning it into profit using complex reactions. I intend to take you from start to finish in making Sylramic Fibers. Lets get started.

First of all, I've done the hardest part for you. I've picked out something for you to produce. If you didn't know yet, you'd want to do the research yourself into moon products. I use this tool to tell me what I can make with the resources available to me: Reaction Materials Info Page. One of the most important factors to your profitability is what you can get for free. That means asking yourself "which moon resources, no matter how cheap, can I get a hold of?" Once you know that, you'll be further on the way to deciding what to produce.

If we look at that page, we can see that Sylramic Fibers are made from Ceramic Powder and Hexite. If you click to look at the full bill of Materials, you can see that Ceramic Powder is made from Silicates and Evaporate deposits, while Hexite is made from Platinum and Chromium.

The thing about POS's, is that you want to keep the raw number of POS's to a minimum. A large POS is the standard for fuel counts. Mediums take half the fuel of a large, and smalls take a quarter of a large's fuel.

So why does it matter if I use 4 smalls or one large? Lets look at the numbers for a Caldari Large, Medium, and Small Tower. These numbers will assume your alliance has sovereignty on the system in question(Which reduces the fuel costs).

Caldari Large Tower(1 Hour of Fuel):
Coolant: 6
Mechanical Parts: 4
Oxygen: 19
Robotics: 1
Enr. Uranium: 3
Nit. Isotopes: 338

Caldari Medium Tower(1 Hour of Fuel):
Coolant: 3
Mechanical Parts: 3
Oxygen: 10
Robotics: 1
Enr. Uranium: 2
Nit. Isotopes: 169

Caldari Small Tower(1 hour of Fuel:
Coolant: 2
Mechanical Parts: 2
Oxygen: 6
Robotics: 1
Enr. Uranium: 1
Nit. Isotopes: 85

Pay special attention to the Robotics, Enriched Uranium, and Coolant numbers. Oh, and use this tool to plan out your POS setups.

You'll notice that the numbers don't scale down the way you'd expect. That's because EVE is pretty unforgiving in rounding. That and the fact that you can't use less than 1 robotics an hour. 4 Smalls actually cost a significant bit more than 1 large(Since, besides Isotopes, Robotics is the single largest cost associated with fueling), while the capacity of the POS's in CPU and Powergrid aren't increased at all. You can do as much on 1 large as you can do on 4 smalls, but pay less to do it.

There are a number of applications for smaller towers in EVE, but for complex reactions, it's almost all Large Caldari POS's.

So now you've decided on the POS to use. You'll generally want to run POS pairs for less complicated complex reactions. Sylramic Fibers is one of those, so we'll talk about why a POS Pair is a better choice than just one POS.

You produce 2X the profit. If you want to just do a complex reaction from entirely bought simple reactants, a single POS is fine. You'll make more money, and find it much easier to use available resources though, if you do the simple reactions as well. I'm going to provide you with an image, that should help somewhat in explaining this.

It's pretty complicated, but the information is all there. So each POS needs at minimum 3 Silos, 1 Complex Reactor, 1 Simple Reactor, and a choice between 1-2 Moon Harvesting Arrays and 1-2 Silos. If you're really very lucky, you'll get two moons in the same system with all of the resources you need. Otherwise you'll be stuck with the setup as displayed in the image. This is usually still profitable(check your numbers) but not always. So be careful.

So I'll explain the setup in words alongside the picture.

POS 1:
Mine or Transport in Evaporate Deposits and Silicates
Using a Simple Reactor, turn Evaporate Deposits and Silicates into Ceramic Powder. This will produce 200 units per hour, and consume 100 of each of the reactants.

POS 2:
Mine or Transport in Platinum and Chromium
Using a Simple Reactor, turn Platinum and Chromium into Hexite. This will produce 200 units per hour, and consume 100 of each of the reactants.

POS 1 and 2:
Transport 17k Ceramic Powder from the First POS to the Second POS, which is producing Hexite instead.
Put the Ceramic Powder into a Silo.

POS 2 and 1:
Transport 17k Hexite from the second POS to the first POS, which is producing Ceramic Powder instead.
Put the Hexite into a Silo.

Both POS:
Using Complex Reactor, turn Hexite and Ceramic Powder into Sylramic Fibers.

After a week, come back, pull out all the Sylramic Fibers and transport the stuff across POS's again.

After a month, what you have should pay for the POS fuel for the next month, with some profit besides. Here's a link to the POS setup(Note, you will need two of these). And yes, you've got 500 CPU free. Enjoy putting up a lab on one, and a few production facilities on the other if you'd like.

Here's a link to a spreadsheet with current prices(As of this post).

There are many other methods and ways to do this. There is no one way to handle it. You'll have to figure out what works best for you. This should get you started though, so enjoy.


  1. Some things.

    1) You can only do this in .3 or lower
    2) The Isotopes are the most expensive part of the fuel. (your not taking into account the added requirements for the online modules).
    3) You can only setup 1 POS per system per day in lowsec.
    4) Do your calculations CAREFULLY.
    5) If working alone. Make sure you are a POS gunner.
    6) Flying a freighter into Lowsec is dangerous, this is where 2 accounts really help 1 flying freighter, 1 webbing it.

    POSTracker is an epic web app. you want the "FGV" version (Frozen Guardian Version).

    There are a lot of other things to talk about when setting up POSs but that is beyond the scope of this comment. I had all kinds of help from somebody and about the basics of setup and still have issues sometimes.

    While running reaction POSs can be a lot of work in setup, they can produce enough isk to be worthwhile. Im glad I got into it. Thinking of setting up 2 more towers.

  2. Could you run 6 silos and 2 complex reactors in a large caldari tower?

  3. Can two arrays feed/deposit into the same silo?

  4. If someone wanted to just run one POS with simple reactors - it seems like you could fit 3 simple mobiles and the associated silos and a few guns and ECM. IF you could not get blown up for just one week you could make your ISK back in 10 days. Is that about right?
