How much media?

[bradleyheathhays]

Feeling like I should have been able to find this listed somewhere in the lit but so far I haven't. I've got two new Eheim 2078s which I think are also referred to as 700s and I'm trying to determine how much of the Mech and Substrat Eheim media I need to get for them. The manuals show the bottom tray to be filled with Mech and the other three to be filled with Substrat. Found a deal for 5 liters of mech for 80 bucks which seems like a good deal when compared to the by the liter price, and if I'll eventually use it then seems worth it. But if 5 liters is way too much then I'd rather save the money.

Any advice?

Hey, nice filters. This is how i would set them up, starting from the bottom up...
1. Course Filter Pad(Traps large particles)
2. Full tray of Seachem Matrix(Bio-Media)
3. Full tray of Seachem Matrix(Bio-Media)
4. Full tray of Polyfill/Filterfloss(Polishes)

With the third tray of Polyfill/Filterfloss, i use cheap bed pillows. They are only a couple of Euro's but if you live in the US, i believe the polyfill is widely available from Craft/Hobby stores, very cheap. This stuff will last a very long time, a couple of years!!. I don't have your model of filter but most canisters can be set-up this way... In your case i would fill the last tray(top) with the floss and put the fine/polishing pads on top of the floss. This will stop any loose floss from entering the motor and clogging the impeller.. I would put a 100g bag of Seachem Purigen on top of the top pads, so it's the last media that water passes through...
With this set-up, you will have sparkling crystal clear water.... Ian
