Using Internal Filter As A Pre-filter For External Filter Options

[leochm]

Sponge filter (guppy brand) simply superb.
Canister - Eheim 2213 I can't say more its great
Eheim Liberty - Very good mech filter, handles the shit issue together with my tom battery cleaner, just keeping everything clean.
Tom Dive Clean 85B - My prefilter for Eheim 2213, the secret of less maintenance for my 2213 and my prime assist.
Rena Air 200 - simply the best power for my 2 sponge filter.

Lionhead - the magic to the coloration and growth of my very ugly fish. Seriously!

Hi All

I read this post by jhansolo that was posted quite long ago. Just like to find out, is it a
common practise to use an internal filter as a pre-filter to the external filter. How do you know whether
the internal mechanical filter is suitable for your external filter. Curently, im using a eheim 2213 ext. filter with an pump output of 440l/h. If i want to attach a internal filter, should i get one with a higher pump output?
The reason i ask is because when i tried attaching one of my old jebo internal filters to my 2213, it seems like the flow rate is kind of slower as compared to when im using the internal filter on its own. Has anyone face the same problem before.
Please advised.

Thanks in Advanced

Hi gohks

Thanks for your advise.
By the way, i have already converted my 2213 into a bio-filter yesterday(thanks for your recommendation again),will monitor the nitrate lvl.
Since you were saying the pre-filter setup will not help much, i was thinking to add another over-head filter on top of my current setup. The gfs are producing too much poos, too much for 2213 to handle. Can i also use back the same setup as what you recommended for my bio-filter. Please advise.

Not sure your setup can remove nitrate if this is your concern. There are other means to remove nitrate already discussed in the forum before.
As for the OHF, not sure which type you getting, (wet, wet-dry....). Slightly different setup, 1st layer at water inlet usually fine foam to mechanical filter off the particles and dibrics (as water inlet will be spread by plates), before the water reach the bio material. As space is usually limited, sponge or bio mat is usually preferred.
