Resistance is futile, you will be administrated!
Devil's advocate... it really proves nothing much. Try another batch of shrimp with proper acclimatisation and see if they perish. Then you can say whether it's truly due to the pH difference or something else in the tank.

Vinz, the shrimps were tested by several batches of 20 for O2 deficiency, nitrite and Nitrate. But I agree got to wait for the next trial before I finalise the verdict.sorry for jumping the gun, folks. I'll be back.
Ot a little, by the way anybody tried Seachem equilibrium? Is it useful in this situation? Thanks.

Michael, is it the tank that you posted in the aquascape section with the issue?

Hi Peter,
Unfortunately it is, if you look at the 1st picture you can still see a dead shrimp. Any proposals?

Pottassium overdose? Apparently shrimp are sensitive to this Macro fert?
How about the Temps, is it very warm in Singapore right now (or is that a silly question
Unless something in the tank is chomping on them? With all the dying BBA perhaps also your ammonia levels are high?

Have some surface movement. Its fine if you lose some CO2 but the surface movement does add O2 in from gas exchange 24/7. I'm guessing from the look of the pictures that you do not have any at the moment?Originally Posted by michael lai

I'm actually having alot of surface action because the fan is very near to the water surface plus the addition of a powerhead with air intake for night use. O2 shortage is therefore rule out. sigh...

Not sure about potassium overdose but come to think of it all this started when I start to use Dr Mallick's fert, hmm.......might be worth exploring. Temperature here hovers around 30-34. We use fans to bring it down to around 27, quite safe for most shrimies.

I'm not sure if the surface movement from the fans is enough during the day but maybe you can consider adjusting the filter outlet such that there is a moderate surface movement. Just give it a whirl and see if things improve.

Ok, will give it a go, might even introduce one of Tom's (barr) diy powerhead Co2 diffuser later on. If all else fails, I'll have to tear the scape apart. I'm contemplating replacing the substrate as well from onyx to amazonia or malayan. I'm experiencing some problems with the substrate, it is 'compacting' and some of my crypts are suffering....

mind telling more about the onyx sand problem?Ok, will give it a go, might even introduce one of Tom's (barr) diy powerhead Co2 diffuser later on.

i was contemplating using onyx sand for my next tank
btw, anyone has any comments about about dennerle quartz gravel as well?
considering that too.
The tank is "pretty packed" and good circulation might be an issue as well. How big is the tank and what filter are you using? Do you have additional source for water movement?Ok, will give it a go, might even introduce one of Tom's (barr) diy powerhead Co2 diffuser later on.

The only thing that can kill shrimps are NH3, low O2 and a large change in "salt content" from the water it is from to the water you dump them in (osmotic shock). What is the KH of your tank water?

I've gone well over 100ppm with K+ andf with NO3, no impact on shrimps till get above 120ppm with NO3, never found any issue for any plant or fish/inverty for K+, many folks in the SF area dosed 50ppm K+ or more for about 6-8 years or so.

Hi lee1224,
Some of my plants like crypts and criniums, the roots are turning black due to don't know what reasons. Not all of the crypts though, the beketti( I hope I got that right )is okay but the undulata just withered off. The 'Kraken' that you see now is planted in a plastic tub hidden from view. From the affected plants area when I pull out the sand was very 'fine'. That's why I came to this conclusion. This is only an assumption, there might be many other reasons.
As for Dennerle quartz, please refer to my 4 footer scape, 'plug & play'. I've got no complain except maybe the price.

Thanks, Tom for that information. I'm quite bad with all this alphabets and numbers so sometimes you'll have to bear with me.

Pete, I'm using a Ehiem 2215 plus a small powerhead( just added ). The tank is W900 x D450 x H600mm. Don't have a KH test kit now, I check on that later.

Hmm.. dennerle quartz is that ex???As for Dennerle quartz, please refer to my 4 footer scape, 'plug & play'. I've got no complain except maybe the price.
think i only ever checked out its price twice before
1st time i saw was near 50 bucks a pkt at lfs A (no naming here on prices i guess)
then I do recall seeing a certain lfs B selling it at $18 a pack.............
thats 1/2 the price of a pkt of ada!!! and much cheaper than what i saw of its price the 1st time
i remember that cause when i saw the price tag i couldnt really believe it
and i checked with the shop owner twice! and he confirmed with me 18 bucks
i was quite surprised...wondered if it was mis-priced
too bad it was quite far from my home and i was jus passing by that day and browsing when i noticed the lfs
was on the way to an appointment
if not i probably might have bought a few pkts and lugged them home and congratulated myself on a bargain

Hi lee1224,
The price is for a 10kg pack, I searched around and have never heard of a 10kg pack going lower than $40 bucks. It's 3 packets in one box. You might be looking at a smaller packing( 5kg ).
Additional information.
The sand is synthetic( man made ), does not affect water parameters, rounded( as in no rough edges ). One of the most consistent in terms of size and colour. But left a big hole in my pocket.

even if its a 5kg pack its still slightly cheaper than what it shouldHi lee1224,

but i believe i saw a 10kg pack though
hmm maybe i should go back to check it out and get myself a few bargains
