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

Hi, can anyone answer this for me...I'm setting up a 450L malawi cichlid tank and i was wondering if i was to use a different substrate to crushed coral(was thinking of normal aquarium sand)would i have enough buffering effect if i was just to use coral in the filter baskets.
I'm going to be using 2 external filters.

Thanks for any replys.

Really depends on the source water, what your using to fill the tank, do you know if the water is hard, has a high PH etc???

PH is 7.4 not sure about the hardness of the water.
Livin in the dublin area if you happened to know what it's like around there

its a bit hard to tell at the moment.. in 5 months my water has gone from PH 7.8 TDS 800 to PH 7 TDS 200 your water will be very much specific to you locality.

Going on what you posted and addiing crushed coral t the filter will be something you will have to try by adding some in then measuring the PH and Hardness.. if you go to your local fish shop and buy a GH (general hardness) & KH (carbonate hardness) test kit. get your tank ready and add the crushed corals a bit at a time and post the results.. there are plenty of people on here to help.. :)

have a look at this link if you want to know more about hardness.. www.thekrib.com/Plants/CO2/khgh.html
