Lyana Posted July 31, 2015 Report Share Posted July 31, 2015 So probably a stupid question, but would levels of nitrates in the 40ppms kill off TBs? They were all fine for the first two months then I took out the purigen and the nitrates went up. Now they're been slowly dying off. I can't think of anything else that's changed. My prls in the tank next to them are doing good with two berried ones, they have same perimeters but I left the purigen in so nitrates are 0.

Shrimpy Daddy Posted August 1, 2015 Report Share Posted August 1, 2015 If the NO3 is produced naturally, at 40ppm it will not kill the shrimp. Unless it is caused by fertiliser. High5's 1 Quote Link to comment Share on other sites More sharing options...
Lyana Posted August 1, 2015 Author Report Share Posted August 1, 2015 I was using the revive growth in the tank before I tested the nitrates. What could be killing them then? Quote Link to comment Share on other sites More sharing options...
Shrimpy Daddy Posted August 1, 2015 Report Share Posted August 1, 2015 It is the waste material that accumulated after you removed the Purigen. I have a couple of tanks, I purposely pump up the NO3 to 50ppm by leveraging Revive Growth (I'm doing testing) and the shrimps are still happily living inside. I'm intrigued by this and have been spending a lot of time these days to find out why NO3 introduced by Revive Growth does not kill shrimp but KNO3 and Urea do. For your problem, I will suggest to put back the Purigen and perform the water restart according to this article: http://www.shrimpydaddy.com/pages/water-restarting-procedure Lyana 1 Quote Link to comment Share on other sites More sharing options...
Lyana Posted August 1, 2015 Author Report Share Posted August 1, 2015 Thanks, on the bright side I have a berried mischling today Quote Link to comment Share on other sites More sharing options...
Shrimpy Daddy Posted August 2, 2015 Report Share Posted August 2, 2015 Thanks, on the bright side I have a berried mischling today Congratz!!! Just monitor further and if the problem persists, then it is better to do a water restart before it is too late. Quote Link to comment Share on other sites More sharing options...
Lyana Posted August 8, 2015 Author Report Share Posted August 8, 2015 I added purigen but the TB are still dying, only have two left guess I need to do water restart. I wish I had just left the purigen in, all tbs were heathy until I took it out. And my other tank set up in the same way and same time is doing great, only difference is I left purigen in.

Lyana Posted August 15, 2015 Author Report Share Posted August 15, 2015 No more dead since adding purigen, but I wonder what's building up in there? Quote Link to comment Share on other sites More sharing options...
JamesHe Posted August 15, 2015 Report Share Posted August 15, 2015 High NO3 level would affect shrimp overall health, and shorten their life span. Quote Link to comment Share on other sites More sharing options...
Lyana Posted August 22, 2015 Author Report Share Posted August 22, 2015 They are still dying, nitrates are under control now, but still slowing dying one every couple days. Quote Link to comment Share on other sites More sharing options...

Shrimp Home Posted August 25, 2015 Report Share Posted August 25, 2015 I used Seachem Prime to lower NO3 to < 10 ppm.... but I realized one more thing: seachem prime make TDS and GH increase. Any solution better ??? Quote Link to comment Share on other sites More sharing options...

revolutionhope Posted August 25, 2015 Report Share Posted August 25, 2015 im pretty sure the packet says that prime binds with nitrate but only for up to 48 hours Quote Link to comment Share on other sites More sharing options...
Shrimpy Daddy Posted August 25, 2015 Report Share Posted August 25, 2015 Bind = React, not equal to lower. The NO3 is still there and will be release back after sometime. Here is their marketing message: http://www.seachem.com/Products/product_pages/Prime.html It used "detoxified". The only way to reduce/ lower NO3 is to oxidize, reduce or breaking the compound through bacteria or consumption. Since NO3 can't be oxidized further and if you reduce it will become NO2, which is worse, then will only can rely on microbial or plant to consume them. revolutionhope 1 Quote Link to comment Share on other sites More sharing options...
Shrimpy Daddy Posted August 25, 2015 Report Share Posted August 25, 2015 Forgot to mention this. Although Prime is a very good dechlorination product, it's active ingredient has to be handled with care. Any dechlorinator that smells like rotten egg uses sulphur dioxide as an active ingredient. Sulphur dioxide is very effective in reducing chlorine and chloramine to become chloride. Sulphur dioxide is a very effective anti-fungi and anti-mould agent. Hence at high level, it will kill shrimp and microbial too. As such, I will strongly discourage to dose Prime directly into the shrimp tank. If you are using tap water and is treating with Prime or any dechlorinator that uses same active ingredient, it is better to prepare the water over night and gas off the sulphur dioxide first. svetilda, nicpapa and ElevateShrimp 3 Quote Link to comment Share on other sites More sharing options...

revolutionhope Posted August 26, 2015 Report Share Posted August 26, 2015 didnt mention - if you have a filter with room for media ie canister then you might want to check out purigen/macropore. it will not lower nitrates but it will keep nitrates low once you have already got them low with WC and/or plants sucking them up! :-) wooops just saw purigen haa already been discussed lol sorry Quote Link to comment Share on other sites More sharing options...
Lyana Posted September 25, 2015 Author Report Share Posted September 25, 2015 Sorry for late reply. I was doing 15% water changes. I think they might have an infection because I saw one shrimp with its nose curled in and the wiskers fell off. Quote Link to comment Share on other sites More sharing options...
