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

Difference between internal and external filter

What are the difference? Do they both do the same thing but at different scales?

Identicle in action but different in a few ways, the volumes differ greatly, the flow rates differ hugely.

An internal releases heat via the motor casing directly into the body of water, the external releases the heat into the room leading to slight heat loss in the water making your heater work a bit harder. Externals make cleaning easier as you don't need to take off lids of Aquaria and they also allow you to add things like Carbon, Peat and Peat granules, Water softening Pilows etc etc etc.

Very generally,internals are for smaller tanks,although we do add some to larger tanks that have an external,for certain purposes,eg,specialised media,wter movement,etc,etc.

Both types have their own merits,but I prefer externals.They easier to maintain,dont take up tank space,can be hidden out of site,less likely fish can get trapped between them and glass(I've lost fish that way),and you dont have an electric cable running into an electric gadget in the water.

Are you looking for a filter for a specific tank,if so what size is it?

always on the lookout for interesting corys.pm me if you know off any!

I've just bought an eheim classic 100 (288l) and I'm sticking in a 2217

Was interested to see what the difference was because before had I thought it was just size

I've a question too. Would you get the same filtration out of an internal that does 1000lph as that of an external that does 1000lph

I doubt it, the surface area on which the beneficial live will be much bigger in the external, the plastic surrounding the holes in the sponge, if spread out would equal many meters of area like the Human lungs so they support innumerable colonies of good Bacteria, although you are getting the same flow of water, your internal would clog much more quickly slowing your flow considerably.

Theres prob different trains of thought,but to my simple mind,the more filter capacity,and the slower the turnover,the better the filtration will be.


That Kev fella keeps typing faster than me.
