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 Guys,

Anyone know of any side effects on Shrimp using JBL Manado substrate, please read the attached Web page.

Apols, did Forum search and found info, remove post if necessary.

To be honest, I haven't a clue, I think reference was made to a thing called microsiemens, which, again, I think, refers to electrical conductivity which is supposed to have negative effects on Shrimp of a sensitive nature, I'd imagine the run of the mill ones like Cherries, Bamboo and Amano Shrimp wouldn't be affected, only ones like Crystals, Bee, Tiger etc would be affected re their reproduction , I'd ask Mariusz to step in here or Daragh if he sees this Post.

I got a load of cherries a couple of months ago,and used some old Manado,there is no breeding in the tank. My last cherry tank had bare bottom,and I couldn't keep up with the rate of breeding.

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

I don't keep shrimps, but this is quite interesting as there are some general conflicting views on Manado.

Having taken a really close, microscopic view of manadao, it looks no more interesting than crushed Red Brick, that's a totally layman's view but I am totally open to contradiction. It has been reported in a planted tank scenario to be a wonderful repository of nutrients in an already established Aquarium, note, it contains NO saturated nutrients , only absorbs/adsorbs, never can work out the difference, enter Ian G please, nutrients which are available to roots looking for grub to fulfill their appetite for the Macro/micro nutrients in their attempts to grow luxuriously in a home Aquarium environment.

Heavens but don''t the intricasies of an Aquarium lead to questions regarding the whole science/theory of our existence, given how fragile everything we deal with within a Glas cube?

Kev.

In a very philosophical vein at the moment lol.

Red brick is probably a very close conclusion. It is probably a volcanic ash of some sort, but I could only speculate as to where it comes from exactly. Not much difference between red-brick and red volcanic ash though, especially if the volcanic ash has clay-like properties.

Clay....what a wonder of nature. I love fish-keeping and clay in the same sentence.

The only problem that I have with Manado is where it gets churned up and wears away the filter impeller a little too quickly. But, that is my fault for not making sure it can't get churned up.

My understanding is that it isnt a live soil but over time it can absorb nutrients and store them in it.


Say compared to ada witch is very much a live soil with ferts in it.



I find it strange it has an impact on shrimps breeding would love to know why exactly or might of been a once off bad batch of a different filter that you had in the set up.


Or did shrimp get berried at all.

The reason this would interest me is that shrimp would live quite close to the manado. There are many substances that exert a local chemistry (well...it's an electrochemistry really).
I use Manado for its general electrical properties in the water, but the fish don't live on the stuff.

As manado has a localised electrical property then that could affect species living close to it.....but it maybe that that effect is only effective within mm of the stuff. I wouldn't know the exact distance as I haven't done any work on it though.

It would be good to hear other peoples experience with this.

Some of top breeder all over Europe is using manado to breed crystals and even taiwans.
You can blame manado for no breeding. Its shrimps nature and then water parameters plus maybe some stress in tanks.
I have over 150 red crystal offspring in one of my tanks and become to small so i moved adults to bigger tank and its over 4 weeks now with no breeding.
I have them in 3 different tanks. One is same as they come from, other too different and no breed in any of them.
It takes me 4 months when I got my firs red crystal.
But I know for sure manada its ok for shrimps - I dont recommend for plants.

I probably wasn't thorough enough in my reply. I'm certainly not putting it down to the Monado,that is just one difference in the tank. I have not tested the water either,for example. In this tank I'm feeding JBL Novoshrimp,whereas the last one they got JMC Catfish pellets,and a couple of other 'pleco wafers'. I occaisionaly throw in the JMC pellets,which they love,but arn't too keen on the Novoshrimp,it seems to be eaten only as a last resort.
I won't now know why the breeding isn't occuring,as a couple of weeks ago I put in a shoal of morpho tetras,so if any breeding occurs,I won't see any shrimplets(is that the correct word?). However,I don't see any females carrying eggs. Maybe I just have 3 or so dozen males? There's so many different possibilities.
It's like everything in fish-keeping,nothing is set in concrete,what works for one,may not for another.

I did have a good laugh a couple of weeks back watching one trying to catch a dapnia,he was all over the tank madly trying to get it. :laugh:

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