Reply With QuoteCould it be the coral chips? maybe you should measure the PH of your water
hi all,
need some advice. My crs setup is a 2ft by 1ft tank with canister filter and chiller, running for about 1 month plus, housing some b to s grade crs and cherries. Every few days there will be a casualty. I wonder what's wrong with setup:
soil: ada amazonia
flora: mixture of aquatic plants and us fissidens and riccia, downoi, moss
stone: 1 granite stone, 1 unknown stone (c328 auntie say is wood fossil rock) and some coral chips to push up ph. The 2 stones i tried with vinegar before, no bubbling.
water temp: 24.5 to 25.5
ammonia: 0
nitrate: 5 - 10
nitrite: 0
kh: 1
gh: 5
Can someone enlighten me as to what's wrong because i couldnt really pinpoint where's the problem. Furthermore one of my cherries is currently pregnant and if the water condition really bad then there shouldnt be any pregnant shrimps.

Could it be the coral chips? maybe you should measure the PH of your water
hi magic, my tank ph was initially <6, as i didnt want to open up my canister to add in the coral chips, i left them in the tank itself....
ph currently at 6.1 to 6.2
Check for hydras.
Big ones will sting adult shrimps. I saw it with my own eyes.

At pH that is around low 6, it seems to be a bad enviroment for hydra multiplication. Put in a large snail, that should provide disturbance to small hydra. These are my observation.

hi silane, did a search and read one article mentioning about .."introduce mystery snails..". Any idea what is mystery snail?
Any specific type of snails to put in to the tank, or i can just grab an apple snail?

maybe you should try the anemone snail
Anemone snail?what are those?
Only if you see them in your tank, they hardly can live in acidic tank. Any big snaill will do.
silane
Just like to point out that I've hydras in a tank of mine with low pH, so they might just be able to survive in acidic conditions.
wei, even if you find hydras in your tank I don't think you should use the method recommended in the thread. It is stated that "Copper leaches into the tank via one of the wires", and I think copper is harmful to shrimps.
the problem is i observe till eye pop cant spot any hydras whatsoever...water parameters are all okay...hmm....now monitoring hopefully *touchwood these few days no more deaths...

Sometimes they just die of no reason. But many times is due to old age.the problem is i observe till eye pop cant spot any hydras whatsoever...water parameters are all okay...hmm....now monitoring hopefully *touchwood these few days no more deaths...
Have to be very careful when more deaths are encountered.
annemone snail is a snail that kills and eats other snails, but safe to be with shrimps.. However this snail can move real fast, and hence maybe able to disturb the hydras better than normal snails.. Some shops sells it at $3 - $4
cheers
Never create what you can't control
There is no annemone snail.
To be truthful, it really isn't a good idea to use this snail for your purpose. If you have done your research and read (a lot) about the snail, it is not an algae eater but a molluscivore. Therefore, if you are going to use them, then you will need to supplement with high protein and meaty food in the long term to keep them healthy (and alive).
The question is this, are you prepared to risk polluting the shrimp tank? Any uneaten high protein/meaty food will certainly contribute to substantial waste and this would add to your problem instead.
So if you wish to use snails for your purpose, I would suggest to use algae eating snails instead.
Ive tried this type of snail in a hydra infested tank and they do not seem to bother any of the hydras at all.
They only look out for other snails and are eager of my algae wafer.
found three more up lorry yesterday....so started doing troubleshooting by removing the two small gujings(with sponge)....
maybe will remove the coral chips if things don't improve...
There's a few small dark grey snails in my tank. I suppose they are harmless to shrimps right?

Your tank, somewhere, somehow has lost the balanced, deaths will only slow down when the balance is back again.
silane
The exasperating part is to pinpoint the exact problem.
A kind forum bro gave me a thinker...about toxins in the water (pesticide from plants etc). Since there's another new death today, i have moved on to using Activated Carbon to improve then water quality see if things will improve or not.
Let us know if it activated carbon helps.
My guess is it will not... I got a feeling is something else.
silane
You might wanna try dropping a ketapang leaf into the tank
Had a colleague with similar issue. Same tank, cherries survived. CRS jsut dies
Gave her a big ketapang leaf to put in the tank. New CRS are surviving now. Might be a coincidence of course.
