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

Just wondering what people think of this....?

www.cichlid-forum.com/articles/ug_jets.php

Was think of doing it in a 400L planted tank, using the power head from a rio 180 internal filter.

its a homemade version of reverse flow filtration, which used to be very popular and it does work very well. a lot of marine tanks were filtered this way usually linked with external power filters.
an easier way to set it up would be to use normal undergravel filter plates and uplifts and attach powerheads blowing into the uplifts rather than drawing water out.
i'm not sure if reverse flow would suit planted tanks.

30 tanks specialise in african cichlids, angelfish and various catfish

The idea i have is to use it not as an extra filter but to add abit more water movement and direction, thats why i was gonna use the powerhead from a rio 180 in the 400l so it wouldnt have too much power behind it.

Its kinda just for flow more than anything esle.

I think you would be giving yourself a lot of work for little return in a planted tank.
I have seen this system used on heavily stocked Cichlid tanks and the substrate was still dirty. They still had dead spots.
The substrate would have to be deep enough to cover the 3/4" pipes.
An alternative to this would be to have a spraybar run the width of the back of the tank with the powerhed attached. Have the spraybay face to the front of the tank.
I think you would be better of just sticking the powerhead in the tank once a week and gently blowing any dirt that accumulated around the plants.
