My shrimps died previously due to ceramic rings too, after i change to some sponge as media, deaths stopped, dunno don't know why too...
Any idea if ceramic rings causing shrimps death?
Recently removed ceramic rings from HOB filter and death has stopped. Must be something in it thats affecting the water in tank. Previously, shrimps death an average of 1 every day or two. Weird but then again, shrimps are one of the sensitive fauna that i've ever come across. Will be observing conditions over a week before i also remove ceramics in HOB filter of another tank.

Were the ceramic rings recently placed in the filter as a replacement for other media? If it is then maybe there's not enough bacterial colony to convert into harmless ammonium. So there could be an increase in ammonia that's accountable for deaths.
Or another reason I could think of is that the brand new ceramic rings have those powdery particles.
But if at the start of running the filter with ceramic rings, I think should be alright. I'm using ceramic rings in my canister filter so far no problems.
God will make a way, where there seems to be no way


Which type are you guys using? the sintered glass kind of the normal ceremic rings type? I'm facing some sort of problems too and i suspect its the ceremic rings. for 2 weeks my tank was running fine. life stock all ok. when i changed 1 tray of media (total 3 trays in filter) from lava rocks to brand new ceremic rings, my tanks stocks were wiped out. everything that goes in dies. I'm still wondering if its due to my ada giving me problems or the ceremic rings or etc etc... i'm troubleshooting 1 by 1. terrible nightmare... cannot slp man... been thinking abt it for a week now.. but from what my test kit is showing, all my readings are 0ppm. even nitrates are 0... Btw the tank is cycled for 1.5 mths already.
So as what bro lee is saying, cant be new rings thats why bacteria not colonised etc. leading to shrimps dying. Cause i only changed 1 out of 3 trays and theres only few pieces of livestock in there. bioload almost non existant.

Did you guys wash the ceramic rings before adding them to your filters?

yes.. washed throughly.



Guys, I am no expert in this at all but one bro I know is cycling his new tank with the sintered glass (I don't even know what this is, I am repeating his words), brand new tanks for his altum angels... but his pH reading is 9. Even after trying with K leaves to lower the pH, it is staying at 9. Sure die for altums. Does this help in any way? Apologies if it doesn't.

I'm using Ehiem ceramic rings. Comes with the filter. Should be the normal type. That's strange. What about your pH and kH?
When you change your media, did any particles or dirt flow out from your filter? Cause sometimes the shrimps are sensitive to these particles. Just like when you rescape your tank eg pulling of root plants, shrimps will also died due to sensitivity.

oh dear, i do have unaccountable death 1 or 2 every other days too. At first i thought is drayonfly nymph. But i took out all plants and check, confirm no bugs. Same thing like bro barra21, all parameters are good. Ammonia, nitrite and nitrate are 0 ppm. PH is quite alright too.
I am also suspecting small traces of copper from the tap water, so i added EASYLIFE and AC.
Dont tell me is the ceramic ring. i think i better slowly replace the ceramic ring by BIOHOME..![]()


mine is the eheim ones too. sintered glass. i'm really clueless. i removed all of them. i'm hoping this time things will go smooth. I cant afford to lose anymore livestock..

That's strage. I have always thought that ceramic rings are supposed to be inert in nature.
My initial thoughts were that there maybe something on them, hence the question on rinsing before use.
I am clueless, sorry guys about your losses.

yeah if it really is the ceremic rings, it'll be a giant eye opener for all us bros. Cause if we dun use cr then what the hell we gona use? ha whole filter biohome? anyway biohome is also sintered glass... oh man..
I've always knew ceremic rings to be inert in nature too. so when i saw this thread i was suprised.. if only fishes and shrimps could talk.. it'll be so much easier.
This is a nightmare to troubleshoot as it could be anything... cr problem, ada soil problem, lizard coming to the tank to pee, plants rotting, not enuff anti chlorine, too much, etc etc etc...
hai.. but i guess this is just what fuels us to keep on going. We need to know why and how. haha.
I'm just very worried about this issue.. Imagine us bros having an aro/ expensive fish tank in future and we have a sump full of cr that has problem.. we'll never know what killed the fish. and our fingers will definately shoot straight to the PUB with their newwater.... and any fish that goes in will die..
scary thought![]()

Wah, I never thought the shrimps in my new tank die because of CR before. But come to think of it, it is possible. I've always thought it is because of new setup, but been cycling for 1mth plus still got shrimp die 1 or 2 a day. Hmm ... if it's really CR then troublesome. Have to change the whole filter media and recycle the thing again.
Bro Barra, you should keep us updated on your findings after removing the CR. Thanks.

yup i will. i'm praying it works out this time. i'm exhausted... in all areas effort, time and cash.... if this doesnt work out i don't know what else to do. Maybe close it down and concentrate on my other tanks.

I dont think its the lack of beneficial bacteria thats causing the deaths... because my shrimps were doing fine and even mating and reproducing even before introducing the ceramic rings. So far notice deaths only affect the adult shrimps, not the juveniles. Perhaps juveniles got accustomed to the water quality affected by the introduction of ceramics. Shrimp population went down from 70+ to 10+ in about 2 weeks. Even my hardy yamato finally succumbed recently.
Any ideas for a safe replacement for the ceramic rings to harvest bacteria colony? I'm thinking of those big black bio balls. But for those bros with HOB filters like mine, those cant fit. Is biohome safe enough? If it is, then i might make the switch.
I think something in 'typical' ceramic rings thats poisoning the water. There might be an exception when it comes to high grade ceramics like biohome or those from eheim though. Feedback please!


Mine is from eheim bro. ha. but I can't say for sure its causing the shrimps to die. but like your case, my livestock were fine prior to introduction of the ceramics.

Ceramic rings of certain brands, as reported by some aquarists, are known to increase the pH value.
Did you guys do the basic tests for your water condition first and foremost - pH, ammonia, nitrite, nitrate, temperature etc?
These may yield some clues, for example, if ammonia/nitrite/nitrate are of acceptable values, then it is not a problem with the bacteria colonies etc. Or if the pH is registering an unexpected reading, then something may have caused this.
It may be easier to narrow down the suspects by method of elimination.
Just my 2 cents.


yup bro. i'm at my wits end. All my readings were 0ppm. even nitrates which is difficult to achieve with new ada. ph about 7.0. running with chiller. filter running with eheim substrate pro 2 and biohome so its definately not the bb problem. Can't be bioload also as its only few pieces of shrimp. tank cycled for 1.5 mths. moss growing healthy. Something is so wrong, both yamatos introduced tried to climb out of the tank. 1 succeeded. Can't believe it...

To play safe, perhaps the next time we get ceramic rings, we should get a pack of activated carbon at the same time, and soak both of them together for a few days before using it.
