Retirement and forum shutdown (17 Jan 2022)

Hi,

John Howell who has managed the forum for years is getting on and wishes to retire from the role of managing it.
Over the years, he has managed the forum through good days and bad days and he has always been fair.
He has managed to bring his passion for fish keeping to the forum and keep it going for so long.

I wish to thank John for his hard work in keeping the forum going.

With John wishing to "retire" from the role of managing the forum and the forum receiving very little traffic, I think we must agree that forum has come to a natural conclusion and it's time to put it to rest.

I am proposing that the forum be made read-only from March 2022 onwards and that no new users or content be created. The website is still registered for several more years, so the content will still be accessible but no new topics or replies will be allowed.

If there is interest from the ITFS or other fish keeping clubs, we may redirect traffic to them or to a Facebook group but will not actively manage it.

I'd like to thank everyone over the years who helped with forum, posted a reply, started a new topic, ask a question and helped a newbie in fish keeping. And thank you to the sponsors who helped us along the away. Hopefully it made the hobby stronger.

I'd especially like to thank John Howell and Valerie Rousseau for all of their contributions, without them the forum would have never been has successful.

Thank you
Darragh Sherwin

Need advice on pre filter

Just wondering did any of ye using pre filter or mechanical filter before main filter?
I'm running FX5 and after every weakly water change I change dirty filter floss on a top basket in fx5, but a minute I'm turning filter back I'm getting small amount of waste blow back in a tank,
So I'm thinking if I put pre filter to stop some waste going into main filter, I can use top section of fx5 for bacteria filtering.
Any advice?

What are you planning on putting into the second canister? Filter wool? Sponges?
I'm not totally against the idea but surely the secondary canister is not going to cope with the flow from the fx5 effectively?
I could possibly be wrong, but it would concern me that the secondary canister might put unwarrented stress on your fx5 pump?

In theory it might work well enough.... but you would need to be sure the smaller canister wasn't going to slow the out take from the tank to your fx5 too much that the pump would be pushing out water faster than it was being drawn in!

Ie If you went with the eheim idea, and put sponges or something into it, you might need to use 2 of them to match the intake requirements of the fx5?

Every Filter gives a second or two of dislodged mulm and grime but with a Filter like an FX5 the suspended material won't be such for very long, Personally, I wouldn't give it any thought.

I would get rid of the filter floss in the external for the first thing. It is too fine for an external filter if all water has to pass through it.

Having a pre-filter on the inlet is not necessarily going to put a strain on the external. I have large-pore sponge pre-filters on some of mine.
I would not, however, recommend filter floss unless used for a day or 2 to polish the water.

If you need to use floss with an external filter then you could think about setting up a cascade external over which the output water flows back into tank with floss added to that (not in sealed system though as that will put a strain on the external).

But to be quite honest, the fx5 is a big-boy. It has a massive volume chamber and ceramics, open-pore sponge etc (not filter floss) are not likely to clogg so easily and they will also keep the water nice and clear.

The thing is I hate to turn fx5 off doing water changes, I usually do 30% changes twice a week, so in this case I don't need to turn filter off, but if I do 50% water changes, I'm turning filter off cause sucking water out from the tank , the outlet stays out of the water , and no matter how I'm rushing to do this I'm getting bacteria bloom for couple days.
So my idea was fx5 to use as biological filter only.
I suppose I should try to use fine sponge on the top instead of filter floss, I never buy an original fx5 mechanical filtering stuff, I think it is waste of money, I was using floss from the pillow on the top, and in another 2 sections I have seachem matrix, and I find it very effective.
Thanks lads for the advice.
