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

External filter inlet/outlet placement

Hi

Been googling inlet/outlet placement and finding mixed results.

So what do you guys/gals recommend for best flow? I was thinking of changing from opposite sides to same side top bottom to get better circular flow.

Advice welcome
Thx

I think if you have the in and out flow at the same end you might find debri gathers at the far end of the tank. In other words, the flow fromthe filter will carry it there but as current flows down and back around, it'll have lost a lot of its power and just dump waste at the far end. By far the cleanest of my tanks has a spray bar at one end and the outflow at the other. The filter is nothing super-duper, just an Eheim classic, but the water is crystal

Hi

Thx for the reply

When I look at my tank and apply my very simplistic logic without any knowledge of hydrodynamics I kinda think, a three foot tank with spray bar top right and outlet bottom left I would be getting dead water below the spray bar with flow going kinda diagonally top right to bottom left.

If the filter (2217) is strong enough would having the spray bar top left push water across and down the right of the tank and back across the bottom of the tank?

Thoughts?
Cheers

ah, but you wouldn't have dead water below the spray! as the bar is forcing water across the surface, it'll be displacing other water and causing a draw behind and below the bar. I could be wrong, but it seems to work that way in my tank. the only dead spots I ever get in it are caused by tank decor
