No need to use UV for a CRs tank.
You might have to look for any possibility of contamination from either your SS or driftwood.
It happen to me once as well. My crs died one by one for no reason till I found out one of my SS was rusty.
I got a 1.5ft tank setup in my office 2 months ago. Cycling was completed 4 weeks ago using a blood parrot and seeding of media from home's Eheim 2028. The setup is as follows:
Substrate : Magic Soil
Filtration : Eden 501 (300g of biohome), bubble sponge filter
Plants : 3 SS mesh with moss, 3 driftwood with moss
My latest water parameters taken on Thu were:
Ammonia : 0 ppm
Nitrite : 0 ppm
PH : 6.5
I do not have nitrate test kit. I don't think nitrate is a problem as I perform 10% water change every week.
Upon completion of cycling, I used 2 grade C CRS to test the water. They were fine for 1 week. 3 weeks ago, I bought 10 grade A CRS from a lfs and 2 died within the 1st week. I assumed they died due to stress from new environment (it normally happens to fish stock). After experiencing no more deaths for 2 weeks, I bought additional 10 grade A CRS from a fellow forummer last Sat. Since then, I have 1 dead CRS every day. I am now left with 14 CRS.
Can someone enlighten me what is possibly wrong? I am quite demoralised now.
Also, is it wise to setup UV in a CRS tank?
Any advice is much appreciated.

PLee, thanks for your advice. I boiled the driftwoods for 8 hrs. So, I don't think there would be any contamination from the driftwoods. There is no leeching of tanins from it. What do you think?
I better make a trip to NA and get some flat slates to tie the moss to and replace the SS mesh. What a waste, the moss are growing very nicely on the SS mesh.
Sad to know those CRS are dying. Specially select very good A grades for you.
1 thing you can do if put in bamboo charcoal to try to improve your water quality. I have quite a lot spare. You can collect from me tomorrow if you are free.

I noticed that those that died are bigger, which means I bought from the lfs, which also means they were in the tank longer with the SS meshes. I will be heading to office tomorrow to remove the SS meshes and perform 50% water change. And yes, the CRS you selected for me are nicer than what I bought from the lfs. For that, I thank you very much.
As for the bamboo charcoal, I will contact you through pm.

50% water changes is a lot you know....
what bamboo charcoal ?
I was so free I bought some slates from NA and went back to office. 1 of the SS mesh was brown. I am wondering if that is the cause. Cleaned up the slates and tied up some moss to it and replaced the SS meshes. As for the water change, I did about 20%.Originally Posted by PLee
Now, I cross my fingers.
Try a google search.
A website I came across says it can clean up water quality. Its purpose seems very similar to activated carbon.

I've got a similiar problem...
PH 7.0
Ammonia 0
Nitrite 0
Nitrate 0
I'm using a 3 foot tank which explains why the Nitrate is zero, just too much water...
I've got Hogwart which could also be the reason why the Nitrate is zero...
11 ss of Moss... 04 pieces of Lava Rocks
A couple of my CRS have died... I went overseas for 05 days & I found 02 dead... I saw another dead last night...
No change to the tank for like the last 03 weeks...
Only water change... Although I did do a 30-40% water change last weekend... The water in my tank yellowish & I've had this problem when I was cycling it...
Anyway I did a 20% WC last night & my CRS are looking more active now... I'm hoping everything is ok...
I'm also going to invest a product called Power House... It's a media that can also lower PH... Anyone tried it out?
Alot of people in Hong Kong use this...
Growing old with this forum.. :)
Guys, whats the temperature of your tanks?
You can buy that Daiso at a very affordable price.

Mine is running with a Hilea 250A Chiller... Set at 23 degrees...
So far so good after the water change last night... My CRS look more active... Pray no more deaths...

Hi need to check is it advisable to change the ss mess to plastic one for a crs tank cause my crs tank's mosss is all tied to ss. Thanks.
I think my CRS is dying because they have problems moulting. I hardly see any leftover shells.
How can I improve the water condition so that they can moult easier?
Please advise.
Thanks.
There is no need to change the mesh as the Stainless Steels ones are ok... Everyone uses this...
But when you can choose to change to the plastic ones when you re-tie your moss (When the moss is overgrown)
Well you can buy those supplements to improve the water quality but I don't if they sell this in Singapore... I buy mine from Hong Kong...
This product releases Calcium into the water which supplements their intake... You can check to see if Midori carries it... Give them a call...
http://www.midori-sg.com/home.php
Call them to check... Sorry that's the best I can do...
Just some additional info... If you do not see shells it doesn't mean that your CRS is having moulting problems... It just means they are not moulting...
If you do see dead CRS stuck in their shell (Moulted halfway) then you need products like this...
If you can't see your CRS it could mean they are hiding...
But at the end of the day to buy additional goodies like the one to prevent problems is also a good idea...

Hmmm...they did not die in half-moulting position. Why would they not moult? Could it because of insufficient food? I feed Mosura food on Mon and Thu.
Actually, I got some coral chips in my Eden 501. Would that not have the same effect?
2 weeks ago, I had 14 CRS. After I remove the SS mesh and did some water change, 2 died last week on Mon and Tue. On Mon, I also added a UV. All went well until this morning, I found another dead CRS. Till yesterday, all were so healthy and busy. I am so sad.
I'm not saying that they will not moult... It could be it is not time for them to moult...
Well I've heard that when doing rescaping CRS die as well because the subtrate was disturbed... Casaulties also happen when water changes (WC) are done when it is too much... Normally a water change should be around 20-30% of the volume of your tank... If the WC is more than that it changes the parameter of your tank & it happened to me as well... A couple of CRS...
Normally people who keep CRS dun put Coral Chips (CC) in their setup as it raises the PH...
From what I know CC cannot increase the CRS intake of calcium... CC is made of Calcium but I've never heard that it is good for them...
If I'm not wrong your setup is quite small if you are using a Eden 501... What I suggest is that you remove the CC a bit at a time... In the initial stages nothing happens to your CRS but it does not mean ithat problems will not occur later...
sometimes no change is the best thing for the shrimps. Last time, i had the same problem, and i scratch my head and try to adjust this, adjust that...nothing good come out of it. Until, i just leave the tank to stablilise by itself ...eventually the shrimps just get use to the environment and are all breeding well now.
