my CRS shrimps keep dying

Recommended Posts

lebowskia

Hello  I have CRS shrimp tank and everyday 1 - 2 shrimp is dying I don't know why, my tds was high a bit but I'm getting lower tds slowy by change %15 every week now ( before add in tank put in water gh+ and make tds 140ppm) when I saw dead shrimp I think it's peace of shell on it, my tds is 260 ppm now, I will make it lower slowly. I did cycle my tank 2 week before add shrimps, I know it's very little, I didn't know. (sorry for my english btw)

my paremeters now:

tds: 260

temp: 24 degree

I don't know other paremeters but I'm going to buy ph meter, what else can I do? I'm trying everyting, I don't want to my shrimps die anymore, I have left 7 shrimps.

here is my shrimp photo after die:

Sorry to hear you only have 7 left. It may well end up they all die but at least then you can get everything sorted ready for a new batch. Be mentally preparing yorself for te fact that this batch probably will all die off but then you will have a chance to do it properly and don't feel too guilty as we all made mistakes at the start.

Your TDS is way too high still and you really need to get the GH, KH and PH test kits so that you can get more of an overall picture of the water. It may also be that the tank wasn't cycled?

When you change the water you should add the new water very slowly, usually the best method is to use a dripper of some kind! You can accelerate the rate of reducing the TDS by just using pure RO when you do the water change, but that could also prove too much for the shrimp if the new water is added too quickly and the shrimp may already be weakened from the time spent in the wrong water parameters.

Are  you still using RO filtered water using the filter that adds back minerals for drinking? I still think the zerowater jug would be your best bet as then you can still use the other RO water for drinking as well!

If TDS & pH are the only parameters we have, then keep reducing TDS to about 160.

I don't use anymore RO filtered water using the filter that adds back minerals, someone recomment me a spring water here that with right parameters, he said breeding with this water like years and I did waterchange 2 days ago with this water with gh+, my tds is 180 now, better than before I think? 2 shrimps died after waterchange, but now shrimps looks good, there is no death today, I'm really happy not dead any shrimp, I'm going to buy gh test this week, shrimps looks good and moving but there is peace of molt on head 2 shrimps, here is pics, but they are moving, its a big promblem? I hope they don't die,  Zerowater is expensive for me now, I think I will use this spring water for now untill use pure RO water.

Hopefully you are on the right road now and the spring water will work. The new water will usually make them molt. I can't see clearly enough the shell but they may just be eating it, which is normal.

Spring water usually has minerals in it so you will only find out if that is going to work by trial, I hope it works for you and the initial signs  are positive, so fingers crossed.

deaths was stop everythink was good and now start again,  I think I'm doing everything right but I don't why shrimps is dying, my gh : 5, tds: 157, temp: 23 - 24 C, I'm using Ro water now,  I have just mangrow, moss ball, moss, alder cone in my tank, I don't know what is wrong with my tank. I feed them every 3 - 4 days, and if there is left food I put out tank, so I don't think there is much ammonia, it's just shrimps and 3 ramshorn in tank. it's can be bacterial infection? but there is not look like something wrpng on them body.

here is my shrimp after death, look like tail is empty

In the second photo it looks like the shrimp was moulting. What's the calcium content in your water? The shrimp might've died because it couldn't get out of the shell (I don't know much about this, but I've heard about it happening before).

I don't know calcium content, how can I know that?, with test kit? and how can I lowe calcium level?  yes when shrimps is die there is shell piece mostly

I think that there are calcium test kits. A KH test kit may also be of use. But I'm not sure - jayc or someone else will probably know much more than I do on this matter.

It does look like a moulting problem still! Where are you on water, from the above you started RO, then went to mineral water and now gone back to RO? Is this latest RO with the added minerals for drinking or a new one? Moulting problems are probably the most common cause of problems with shrimp.

You say you had no deaths for a while, did this tie in with one of these water type changes, ie have you only recently gone back to RO and that restarted the deaths?

Changing water (especially when with water with different parameters from the aquarium) encourages them to moult so messing with the water as you have been is likely to have been some of the problem.

What substrate are you using?

How many shrimps do you have left?

Calcium is included in the GH test (and magnesium) and that looks about right, though those 2 could be out of proportion. There is a test kit for just Calcium. As crabby says, it would be a good idea though to test KH, for caridina shrimp there should be little to none?

deadts was start like no reason, I wasn't change anything, just weekly same water change (%10 - 15), I'm using Ro water, not with minerals, deaths start before water type changes , I did chage water type 1 week ago, ,tds was 160 ppm when deaths start, and I think maybe  lower tds is will be better for shrimp and I get lower tds to 140 now, I know it's a lot but shrimps already dying and I have nothing left to do,  I have left 3 shrimps now, 3 shrinps look good for now, no any deaths for 1 days. I think I should get KH test. if this 3 shrimps die too I will give up I think..

I use Ista shrimp soil 5.5

      Been a while since I posted in here. Currently running 3 racks but getting a bit too much with family/kids/work commitments. Finally decided to shut down this rack so it is now for sale if anyone is keen. I am in Brisbane. Send me a PM if you would like to view it. Also have heaps of other stuff for sale e.g. Biospon filters, Eheim 2213 and 2215, a few Hailea HC-250A chillers, etc. See my sale post here:  Cheers, JC
