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

Substrate calculation?

Hi

Anyone got a general rule of thumb for going from substrate litres to KG?

It is simple enough math to get litres of substrate required but inconveniently it is generally not sold in litres :(

Thx
Dec

It depends upon the substrate and the state of the substrate.

If it is gravel or sand, then the reagion you are looking at is between 1.5 and 2.5 kg per litre.
Normal wet sand would be looking around the 2 kg per litre mark, standard gravel would also be in that region.

Then there is compaction......if the substrate can be compacted easily (eg sand or peat) then kg per volume is a different matter.

If you have a sample, then it is easy to work out the density by weighing either a known volume or working out the volume of a known weight.

Just had a thought (and it only hurt a little) I have some substrate and a 1 litre jug and a weighing scale. Maybe if I shake the 3 brain cells together I can work something out.

@Ian we were typing at the same time I think I have some 3 to 4 mm gravel that should do as a guide

My guess would be that it will be between 1.6 and 2 kg per litre then.

This stuff is called Jurassic gravel and is 1.5kg/litre but LFS does not have any more grrr. I will allow 2kg/litre that should do it.

By the way where is a good place to get substrate alot of the sites have manado and stuff or 2kg bags of gravel which seem expensive
