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

Sorry for the late reply.

The reason why I added the internal filter as a pre-filter is to cut down maintenance to 2213 which was my main biofilter at that time. My reason to cutting down maintenance is to not disturb the hardworking bugs in 2213. As for the pump output, I don't turn on the pump so it does not matter to me. As for assist to prime 2213 after water change, it works.

As for logical or not ... my conclusion ... it works.

As for your nitrate problem, do a search on my previous post on Seachem purigen.
