Reply With QuoteYou mean IMMEDIATELY??? I think it's better you clarify your post to get better help.
For now, I think it's safer to assume that your tank is not properly cycled yet and the level of ammonia and nitrite is probably too high to tolerate.
help ! what happened when fishes died immediately when i put into new planted tank ?
help ! what happened when fishes died immediately when i put into new planted tank ? i suspect i pumped in too much CO2 gas into the tank causing the fishes to die immediately after i released them into the tank. however i thought new tank shld pump in more C02 to encourage the roots to grow first or some of the unabsorpted CO2 is being turned into harmful materials ???

how long did you cycle your tank? did you acclimatize it first before release it into your tank? or you just dump it to the tank from plastic bag?
yes its immediately . after half of the water changed it still died immediately ( <5 mins) the water is clear , i only do ammonia test , its good nothing wrong , what could be wrong ? initially i only setup for 1.5 weeks until the water gets clear.
i did not dump in like this . i put the plastic bag of fish on the surface for half an hour

What kind of fishes and where did you get them from? Were they healthy and did they have a long journey home before being released into your tank?
fishes from different LFS . the fishes are ok , its my water condition. but dont know what is it
i have found the root of the problem. i bought 5in1 water test kit and found that the KH and GH values are the highest. how do i reduce these 2 water parameter ?

dying less than 5 mins after going into your tank still sounds too quickOriginally Posted by yck
even high ammonia shouldnt kill it that quickly
I think now that the damage is done, there is no point finding out why. Best thing is to change the water in your tank by 50 to 70%, do not add any fauna till 2 weeks, add some bacteria solution and add some blackwater extract to reduce the pH. Make sure you wash your plants before you plant them. Many plants especially direct from the farms have alot of pesticides even they have washed the plants thoroughly.
did you check your tap water kH and gH? Just wondering what is the value. Did you use coral chip in your filter? and what substrated/gravel do you use?
My gosh. I'm sorry for your loss. But even if its cycled for 1.5 week, it should be enough already dependant on tank size. For my 3fts , its enough since i haven't got any loss to date. Good luck and update us bro.

fish: discus/endlers
new addition::: CRS advanture
GH or KH high value is due to metal ions from the fertliser i gues... no i never wash the plants i bought...haha
Ha. Maybe thats why. There might be snails coming out too. Better wash next time. Some bros even use pp to clean them.

Never create what you can't control
Depending on the tank setup and what is done in between, 1.5 weeks of cycle is a rather overly optimisic time to complete cycling. It is considerably better to cycle it longer to more than 3 weeks, even up to 6 weeks.
No loss does not equate that initial cycling has completed. It just means your fishes may have adapted to potential high ammonia/nitrite better. Regardless, the exact way to know if the tank is cycled is that ammonia/nitrite should read 0.
Anyway, the likelyhood that the fishes died instantly reeks of something very wrong with the water conditions.
Ditto
I remember I read somewhere many years back that a complete cycle take 6 weeks, and every time there is a sudden rise of population in the tank, the cycle might restart, as the existing bacteria are unable to cope with the sudden increase of Ammonia and Nitrite.
i think cycling of tank should be 1.5 weeks. at the end of 1.5 weeks, we add half of the livestocks in the tank. thereafter , monitoring is needed. after another 1.5 weeks we add the other half of livestocks. everything need to be in step . the whole thing should take 6 weeks. thereafter , everything should be stable.
So how are you proving your point?
Did you test all your water parameters at the end of the 1.5 weeks to determine if your tank was cycled?
I can tell you that 1.5 weeks is definitely not enough to cycle a new tank, even though I don't know your tank size and what filter you are running.
Unless you are seeding beneficial bacteria from an existing and well established filter, it is still safer to cycle a tank for at least 2 weeks or longer.
If you are still unsure about cycling a tank, you need to do a search on the forum and read about the nitrogen cycle.

I just want to mention one small point.
Please take note that the cycling process only start/take place when there is a constant supply of ammonia/nitrite.
Never create what you can't control
Another point to note is, why half the livestock? If you plan to keep 100 fishes in there eventually, do you actually dump all 50 fishes into the tank within 1.5 weeks?
No, not half the livestock, but a few, 3 or 4 hardy fishes (depending on size of tank) to kick start the cycling. After cycling for a couple of weeks (i.e. after the colony of bacteria has grown substantial), stagger the addition of fishes, e.g. up to 10 fishes, for each/every two weeks until you reach your desired number. The bacteria, which is still colonising, would be able to cope with only that much waste at one time.
Or better still, go fishless cycling.
