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

I have been cleaning / replacing my white filter floss alternately every week (ie replacing it every 2nd week & washing it out in tank water in the interim). I went to buy a nitrate removal sponge today in my LFS & they didn't have the right size (compact). When I asked the guy if it was possible to buy a jumbo one & cut it down to size, he said that actually all I needed to do was pop the tablets out of the centre of it & put them into my existing green sponge.

Is this a reasonable solution? Is there a simpler way of just buying the tablets & not wasting all that sponge?!

What about the blue ones; do they also work in a similar way or is it actual filtration?

Thanks!

Hi Fishie Girl,
i only use one Jewel A record sixty so i not up to speed with their system and never will.

if your tank is cycled correctly beneficial bacteria is spreed throughout the tank.

the floss type filters the water and polishes it the sponges grab the bigger detris.

keep your sponges after washing in tank water and return to filter the floss can also be wash and return but this will need to be replaced as it will brake down

test your water regularly for a few weeks just to be sure!!!

I have one Juwel 70. In the beginning I only had one or two plants. The filter had

a) Coarse blue sponge, never replace it, just rinse in tank water every 6 weeks
b) Fine blue sponge, never replace it, just rinse in tank water every 6 weeks
c) Black Carbon removal sponge, it soaks up bad chemicals, so when its full you must remove it from the tank. Again about every six weeks. When you have lots of plants and you feed them with nutrients, you should remove the carbon sponge, as it will just absorb the plant food.
d) Green nitrate absorbing bacteria sponge. Treat it the same as the black sponge. Again if you have lots of plants you will not need it.
e) White polyester pads to trap debris. Wash each week in tank water.

You may need to replace the blue sponges after a year or so. Only replace one at a time, in fact some people would cut each one in half and only replace one half at a time.

The more you wash the white polyester pads, the cleaner the rest of the filter will be. Also the more plants you have, the less you need the green and black sponges. I have actually replaced them with blue sponges, increasing the surface area for filter bacteria.

Hope this helps.

Personally I never leave my carbon in the filter unless Im looking to get rid of meds. Anyone agree with me on this one ?

i agree with you,carbon polishes the water,it's not essential to fish keeping.
also it's better to not have carbon than keeping it too long in the tank.
saying this it's nice to have as clean a water as possible:)

and just to clarify

blue sponges are your biological filter and yes you don't need to replace them unless they're in bits and yes you rinse them with tank water.

green is chemical filtration,nitrate removal sponge and needs replacement every 6 weeks and yes you can if needed cut one to size off a larger one.

the black one is activated carbon and has to be replaced or removed all together after 6weeks

the white is mechanical filtration needs replacement when dirty

the last one called cirax is the new biological filter medium(maybe that's the one you were told about in your lfs) is a box with white gravel looking material inside which is micro porous(more surface for bacteria to colonise) and should be rinsed with tank water.you can eventually replace the content instead of getting a new one.

hope this helps.

scubadim,

agree entirely. I have no carbon or nitrate (green) sponge. I do have lots of plants. Nirtate is about 20ppm as the plants use up most of it.

At the moment I have white at the to and bottom. Four blue sponges and 1 cirax. As you and fishowner do, I only put in a carbon sponge to remove meds.

I took one tablet out of the jumbo Nitrate removal sponge & put it into my existing Compact one. Is there a way of just buying the tablets instead of wasting all that sponge?

I had a juwel rekord 70 for about 5 years and in it I only used the coarse and fine foam.
I cut the foams in half so that every 6 months I would rinse out one half in waste aquarium water and replace one half every 18 months so that I did not damage bacteria colonies

Ideally, you shouldn't need a special nitrate sponge, as your filter will build up an anaerobic bacteria colony inside the fine foams that will convert the nitrates to nitrogen gas

i'm confused here:are we talking about the same thing?
there's no "tablet" in the nitrate removal sponge...:(

if you don't want to use that green nitrate removal sponge,more regular partial water change does the job.
let us know how you get on.:)

In the Juwel one? Yes there is!

There's a small slit in one side of the sponge & it's easy to pop them out.

See pics taken just now. Only two tablets left cause I have one in the tank (the jumbo contains 3).



I'm already doing 20% PWC each week & with three little people here to look after, I can't see myself changing water any more often.

Well,well,well....we learn everyday!
can't believe i didn't know that after working with those for years:S
getting to like this forum even more.
gotta get more infos on these tabs...

If you're doing 20% water change every week and your population/food isn't extreme
your water quality should be fine and moreover you probably don't need this nitrate removal sponge(with tablets inside:blush: )

They used to have an info. sheet when they first came out in with the sponge, in the box, but think they have since taken it out....

I can claim no credit - the guy in the LFS told me :cheer:.

Thanks so much for the link; it's exactly what I was looking for.
