lti Posted October 2, 2006 Report Share Posted October 2, 2006 On Sunday I added half a bucket of NSW to my mates tropical marine set up. He was very nervous as he prefers to spend huge amounts of money mixing his own water. Today he found one of his cleaner shrimps dead and is blaming me. What imediate actions should he take in case the rest of his fish are at risk? Quote Link to comment Share on other sites More sharing options...
JDM Posted October 2, 2006 Report Share Posted October 2, 2006 do you have the water parameters? sg temp ammonia nitrite ph no3 po4 where was the nsw from? any idea of its water params? Quote Link to comment Share on other sites More sharing options...
slappers Posted October 2, 2006 Report Share Posted October 2, 2006 they are very sensitive to water condition Quote Link to comment Share on other sites More sharing options...
jetskisteve Posted October 2, 2006 Report Share Posted October 2, 2006 You sure? It could have moulted, the shrimp might still be there? Quote Link to comment Share on other sites More sharing options...
lti Posted October 2, 2006 Author Report Share Posted October 2, 2006 from the waitemata harbour. This was before all the rain so the sea would have been relatively clean and was collected on the high tide so as clean as u could ever get from the harbour. It was only 5 or so Litres which is next to nothing for his 200L tank. His water level looked low so i figured it would be good to get a top up. His anemones were looking real sick and figured anything in the NSW would be good for them. Didnt check the parameters before putting it in except the sg was sweet.

lti Posted October 2, 2006 Author Report Share Posted October 2, 2006 hes just checked his parameters. sg: 1.023 (floating hydrometer so pretty inacurate) temp: 25 Ammonia: less than 0.25 Nitrite: 0 Nitrate: less than 0.5 phosphates: dunno pH: 8.2 and he doses with calcium 3+ about 1-2 times a week. Also, jetskisteve he says he isnt a noob and the shrimp hasnt just moulted. but thanks for the advice. Quote Link to comment Share on other sites More sharing options...
Krama Posted October 2, 2006 Report Share Posted October 2, 2006 I think Steve was only making a suggestion, they all help. Could just be a case of timing. I use the same water supply to do my NSW and have no problems at all. The amount you used should not have caused any problems. Quote Link to comment Share on other sites More sharing options...
jetskisteve Posted October 2, 2006 Report Share Posted October 2, 2006 No worries just a thought, why has he got ammonia tho its deadly Quote Link to comment Share on other sites More sharing options...
trinity Posted October 2, 2006 Report Share Posted October 2, 2006 No worries just a thought, why has he got ammonia tho its deadly Sounds like the same test kit i use, it will only tell you less than 0.25 so there is probly no ammonia in the tank.

shaneo Posted October 2, 2006 Report Share Posted October 2, 2006 My hydrometre read 1.023 and the true SG was 1.031, have got a refracto now & no probs. Maybe you should have added freashwater instead of NSW? Quote Link to comment Share on other sites More sharing options...
raeh1 Posted October 2, 2006 Report Share Posted October 2, 2006 I found with shrimps changing heaps of things at once can stress them visibly. Quote Link to comment Share on other sites More sharing options...
Krama Posted October 2, 2006 Report Share Posted October 2, 2006 sounds like I need to get a refracto meter, I just use a hydro meter... where is the best place to get something like this, or are they available 2nd hand? Quote Link to comment Share on other sites More sharing options...
tel Posted October 2, 2006 Report Share Posted October 2, 2006 so you changed 2.5 % and 1 shrimp died. nothing else....nothing else looking affected?? probably because it was just coincidental. the immediate action your mate should take is to realise that stuff dies and sometimes for no apparent reason. if the w/c was poison everything would be floating by now.

wasp Posted October 2, 2006 Report Share Posted October 2, 2006 The water would have had to be INCREDIBLY bad for 5 litres into 200 to kill the shrimp. Highly unlikely, the shrimp just had bad timing. The ammonia shows there is something wrong in his tank, there should be none. This is probably the real culprit. How old is the tank? Sometimes NSW will contain ammonia but it's hard to imagine 5 litres of NSW containing enough to be able to go into 200 litres and still be enough to show on a test kit. If you still have any of the NSW, test that, should put the matter to rest. Quote Link to comment Share on other sites More sharing options...
Pies Posted October 2, 2006 Report Share Posted October 2, 2006 On Sunday I added half a bucket of NSW to my mates tropical marine set up. He was very nervous as he prefers to spend huge amounts of money mixing his own water. Today he found one of his cleaner shrimps dead and is blaming me. What imediate actions should he take in case the rest of his fish are at risk? This is a weird post. Half a bucket into the tank would have done nothing unless it was poisoned. I doubt adding half a bucket of tap water would have had much of an effect. Why did he let you add the NSW if he was nervous about it? Why were you adding water to someone elses tank. Why would you only add half a bucket. Now the shrimp is dead (Steve was right to suggest the Molt, its caught me out many times, infact 2 weeks ago - I guess I am a noob...). And he blames you, the guy who he let put water into his tank? If he can afford to spend huge amounts of money on ASW then why would he care about loosing a shrimp. I find this interesting as what is half a bucket of ASW worth? A few cents most. Then you say the rest of his fish, but none of the other fish have been effected? Just the shrimp? What should he do? He should A. Do his own water changes the way he always has. B. Not let anyone put anything in his tank he is not responsible for. C. Check the tank for the shrimp in question, as I suspect it has molted. All that aside, something about this post smells fishy. Punn intended. Could this be a return of that guy we had a year or so ago? Young guy, can't remember his name, WASP/STEVE/LAYTON you know the one I mean? This post is off.

tel Posted October 2, 2006 Report Share Posted October 2, 2006 :oops: Crikey...ive just remembered :oops: i was out windsurfing a few days ago 'before the rain' and i had to have a whiz.....it was blowing nigh on 30 knots, and i seem to recall i was facing into the wind at the critical point. some may have missed the target :-? (a trusty lion red can lashed to the mast)... this could explain alot, not the least being the ammonia result. Quote Link to comment Share on other sites More sharing options...
lti Posted October 5, 2006 Author Report Share Posted October 5, 2006 well thanks for the advice guys. the problem has been resolved. its just the one cleaner shrimp that died. everything else seems sweet.
