What i do is, i buy the big pack white wool and cut it slightly bigger than the tray.I will fold the side to make it a tight fit in the canister tray.Originally Posted by mercur1al
They are not worth much since it's fairly cheap to buy a big pack of wool and cut, but for lazy people like me who have OCD (diy cut pad needs to be as round and as identical to original pads), it makes maintaining the filter easier.
Though now I am undecided about how many coarse filter pads to use.

I didn't use the blue sponge, all are whites.
Thanks for the tip! That's what I will look to do in future.
Just realized the white sponge I have been using all along is in fact pretty coarse as compared to the original eheim white sponge. Guess they are similar to the blue ones, just different coloured.
Have to hunt for finer white sponge eventually I guess.

Yeah, the coarse sponge used for first stage mechanical filtration is usually those made out of tough nylon material and you can see through it easily... while fine filter wool is like a dense "wool" fibrous texture.
Most people usually buy those rectangular sheets of 3rd-party brand fine white filter wool and DIY cut them to shape (i always pre-cut a stack of them for standby too), because its usually changed at every filter maintenance. Once it turns brown and clogged with dirt its impossible to effectively wash away the tiny trapped particles for re-use anyways.
I never recycle them even though it says reusable.

I just curious; for the inflow pipe(to the filter canister), does it matter if the short end is in the tank or the long end?
Does not really matter as long as fit your need. For example, sometime there are rocks or plants under it, thus you put the short end in the tank.
Yeah, you can position the eheim plastic intake pipe via either end... though it is usually better to have the intake closer to the bottom of the tank to draw in more of the larger debris and sediments washed across the substrate by the flow.
Guys want to seek some advice.
I'm running a 2213 for my 2ft tank with a chiller.
it seems a tad weak but water is pretty much gushing out.
My tank is less than half planted with co2. Small fishes of tetra gourami danion and rummy nose.
Do I need a bigger canister? Classic 350 or economic 300?
Best can used back all my double taps and 12/16 hose and lolly pipes.
2215 is using the same double taps for 12/16 hose

You reckon 2215 good enough?
My output 1 end at the direct opposite end...my long tall grass don't move. Does that means not enough flow? Total fishes 40 to 50.
2215 equivalent will be Eco 300 and pro 300?
But was told classic most reliable. ...how bro?
If the chiller is reducing overall flow and you find that more flow is required, then upgrading to an Eheim 2215 (350) would be good... it has a 620 l/ph flow rate and larger filter media volume, so it'll help improve the overall circulation and filtration.
The Ecco Pro 300 has an even higher flow rate at 750 l/ph and comes with inbuilt taps with an easy priming system, and its more energy efficient (only uses 8 watts), but it costs more, so it just depends on your budget.
The Classic series is considered more reliable mainly because its design is very simple (without any extra features), so there are potentially less things that could break or go faulty. I guess it depends on how careful you are at handling and maintaining the filters.
Thanks UA. So u reckon these models enough?
Cos I feel is not enough now with my 2213 as leaves at the opposite side doesn't move. is that a good gauge?
Either eheim model would be suitable... both will improve the circulation. I use an Ecco Pro 300 connected to Co2 reactor for my 2ft planted tank and the overall flow was just right, didn't need to adjust the taps.
Whether there is enough flow and circulation in the tank would also depend on your hardscape and plant layout, and also the position of the outflow pipe. Adjusting those factors can help improve circulation too.
Ideally most of the plants in the direction of the flow should just be swaying slightly (not too much though, just a little), but even if they don't seem to be moving, as long as you can see suspended particles floating past the plants, it can also indicate there is already sufficient flow in those areas.
The power saving of ecco pro 300 vs 2215 is 8w vs 15w and the ecco has higher flow rate. However I have some concerns.
The ecco pro canister is very small...even smaller than my 2213! So little media. The classic series can have lots of media...that's a big big plus right?
Just worried if getting the 2215 the flow similar to 2213....then I will feel so genna plug.
Got another idea..what if I add a skimmer at the 'dead' corner...just drop 2 dots of coloured medi to see flow...is moving towards the corner....then very slowly back. My inlet and outlet are side by side.
Yeah, the Ecco Pro 300 filter media volume is similar to the 2213, while the 2215 is larger with more filter media volume (less features, more space)... so it'll just depend on whether you prefer higher flow rate + less power consumption or you prefer higher filter media volume.
Installing a surface skimmer and facing it at dead spots or lower flow areas can help, it's quite a common way to solve circulation issues and also get the benefits of removing surface oil film too.
Hijack abit since I saw the surface skimmer bought up.
Saw a few setups when a surface skimmer is used the inlet is opposite of the lily pipe. Instead of the same side why is that so?
I think that's to facilitate flow. Lily pipe out towards skimmer...skimmer draws water in and output 90 degrees from lily. Thus water will move about.
Quick check with you guys running Eheim 2215 with purigen.
Where do you place the purigen pack? Usually, it goes on top of everything, right above the white fine pad. However, the 2215 come with lattice screens, and has a fat "leg" right in the centre.
I am using the 100ml purigen pack with the original seachem bag provided. When placed last and above the white filter pad, the "fat leg" presses into the purigen bag. Concerned if prolonged usage will cause the bag to burst. How do you guys place your purigen?
