you'll get there eventually, just stick with it

I will certainly stick with it, I am as stubborn as hell
On top of that, I get lots of "advice" mainly from people who have no clue what I am up to, and definitely don't have access to all the data from research of AP.
You can't grow plants in stones.
You can't raise fish in tanks with a cover on 'cos there's no light.
etc. etc. etc.
I'll prove 'em wrong, eventually

Hi Dui
How about temperature?
I heard that it's cold in northern part in Thailand. Warm weather fish may not live that low temp.

About growing plant in stone. Last week my mother has realized that some of my plant grow quicker than put them in soil, she told me.

Harsh luck with them fish Dui, push on I'm sure you'll get it all working sooner or later.

Regards people thinking your crazy, its something APers all over the world deal with, once you have piccies of your vegies it'll be all good ;]

Good to hear - it'll work for you eventually !


Just be sure the fish get some light - they don't need a lot, but they do need to be able to see a day/night cycle occuring.

would like just a small hole in the tank cover provide that cycle Rupert?

Damn, 5 more dead this morning, more looking "under the weather"
Temperature might be an issue, or more specifically the temp changes.
It is cold at night Air=16C (water this morning is 21C) and gets hot during the day 31/32C in the afternoon, have seen water temps at 30C/31C.
Would a swing of 10C over night be enough to kill them?
I fear the answer might be "yes"....

I've seen my water temp. go from 30 in the day to 24 in the night, that I've seen but I doubt if the high and lows are more than the degree off, goldies doing fine. How are your other water parameters doing?

Since I added 40 more Catfish, Ammo has come up, but really no more than a trace, a very slight green colour, tested this morning before the pump came on.
Nitrites, again a trace, pale orange colour.
Nitrates 12mg/L.

you have airstones running in there na?

Yup, 24/7

Are you sure the FT and Gb's are not leaching any plastics or any other material into it? that and whats the ph at?

I can never be sure about that, but the tank is manufactured as a fish tank.
The growbeds, I don't know exactly what they're made from, flexible and slightly rubbery.

PH stable at 7 ish.

I will soldier on

[quote="DuiNuiflexible and slightly rubbery.




[/quote]

that could be your probmlem dui. low grade rubber/ platic leaching toxins . . .

I guess it could be, but I would have expected all the first batch to have died by now if it was toxins leeching.
Problem there of course is proving/disproving it without building 3 new growbeds.

I'll just have to hang in there, no more deaths today, but it usually seems to happen at night.
