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

Any problems experienced on having a sand base in the tank and using an external filter.

Gravel can be a detrius magnet as food and waste fall down between the gravel and even when you vaccum you still won,t get it all.
There are many shades of silica sand availble so you can choose on that suits yourself but i would stay away from ther white stuff, looks great when frst put in but cleaning it is a f*****K. I had white silica in a fluval edge and it killed me cleaning it so in a big tank it would be a nightmare.
I have a natural light brownish silca sand in my big tank and it looks class and so easy to clean so silica sand all the way

Have a look on the net of tank setup to see what you like regarding the susbstrate, it always a good starting point when you are setting up a tank

The light brownish silica sand mentioned by Jeff seems interesting.
Sean's experiences with sand highlights some of my doubts on using sand.
I am currently leaning toward the gravel route

My new tank is delayed by another week so I still time to ponder this one

I have discus in tanks with sand, and with gravel, and with peat and also bare bottomed (tanks that is).
The problems really only come when you are not keeping discus water and feeding in good check.
If you do go for a deep bed that easily turns anaerobic (especially compacted sand) then you need to be careful not to allow nitrate level go too low (but you need to have them low enough for discus health).

Controlling NITRATE levels below 50ppm is always a problem for me in my 175L tank with Discus.
I know regular water changes help and I do them. Part of the problem, and I suppose it's function , is that the external canister filter is basically a nitrate generator.
What else can be done to reduce nitrate levels. I know there are some other media to help with this but which is best in your experience ( e.g Polyfilter ; etc)

Thanks Ian on the comments..

Measuring nitrates at low levels is problematic....simply because of limited sensitivity of the standard test kits and the fact that the test kits do not actually measure nitrates.
I personally do not buy into the idea that filters are 'nitrate factories' or 'nitrate generators'....
it is a bit like NOT putting any discus into a discus tank because of them being 'ammonia generators'.
I have seen a load of nonsense on the web written about 'nitrate factories'....most of it is rubbish and misconceptions of the emphasis that the original author of the term.
Anyway, that is a different topic.
My caution was not to do with high nitrates, but to do with having too low a nitrate level in a tank having anaerobic regions (eg in the sand/gravel or wherever).
There is a big danger in using such things as NitratX (JBL) or Polyfilters. I am a big supporter of their use, but they need to be used with care under certain conditions.
If your nitrate levels go to zero, then you are more likely to support the production of hydrogen sulphide in the tank if you have anaerobic regions.
In a fully mature and fully 'cycled' tank these problems are minimised, but it takes an awful long time for a tank to 'cycle' to a level of being mature enough to cope with all these funny little things that can happen.
Mind you, if you are keeping discus then partial water changes are a key element in the keeping of discus....it is not just for reducing nitrates.

I agree 100% Ian and I think that Polyfilter and NitrateX etc. are only to be used in an emergency. A lot depends on the Bio load and the Water volume of the Tank.

The volume of water is a factor. I will be moving to a larger 380L tank soon to allow for the expansion of my Discus stock.
Anaerobic regions in Sand or Gravel is something I need to consider carefully. Thanks for highlighting this to me I need to do some research in this area.
