ilwis Posted December 18, 2012 Report Share Posted December 18, 2012 different species and even individual fish will have different oxygen requirements so low DO in water will affect some quicker than others yip it can also be seen as random deaths over a long time because it kinda goes like this.. 1. fish dies 2. oh no! 3. does water change 4. few days later 2nd fish dies 5. oh shiv! 6. bigger water change (gives more oxygen into the water) 7. few days plus a few days later 3rd fish dies 8. whats going on! 9. series of water changes 10. no fish die 11. stops regular water changes 12. fish dies week later (depending on tank size, size of fish, quantity of fish) 13. is it still not fixed i don't know whats goin on!!!! 14. headache sets in judgement goes cloudy colt 45 looks friendly 15. step 16 gets spread out due to water changes that are sporadic and still not completely fixing the problem 16. fish die faster due to damaged lungs till 1 fish survives (or close to) usually the most active fish the bigger fish or fish that usually live in high oxygen environments die first also sickly fish will sometimes out live apparently healthy happy fish because of this Quote Link to comment Share on other sites More sharing options...

ilwis Posted December 19, 2012 Report Share Posted December 19, 2012 im quite interested in this because i did have the exact same problem before i also had 3 tanks i had a community tank a barb tank and a platy tank, the barb tank was fine but the other 2 was just losing so many fish just as a idea does anyone outside the north shore have this problem? and even more specific outside between northcote and glenfield? im thinking it might be a water supply problem something our tests just are not showing up an odd salt or additive or something the TB idea sounds valid too tho Quote Link to comment Share on other sites More sharing options...
Adrienne Posted December 19, 2012 Report Share Posted December 19, 2012 I am in Epsom and have never had an issue like this with my fish in the 14 years I have lived here. My latest tanks (see this thread viewtopic.php?f=4&t=61015) are also healthy. The only thing I have noticed with regards to water is the very strong smell of chlorine some days from the taps.

alanmin4304 Posted December 19, 2012 Report Share Posted December 19, 2012 When you detect that smell at a swimming pool most people think it is too much ckhlorine but it is actually no chlorine---it has been used up and is now monochloramine. The smell goes away if you add more chlorine. Local authorities try to maintain a small amount of free available chlorine at your kitchen tap but it is not easy and usually doesn't happen.

F15hguy Posted December 19, 2012 Report Share Posted December 19, 2012 our water in NZ is amazingly good, go try the stuff out of the taps in Townsville for example, no chlorine smell but tastes like pool water, and water conditioner makes a heavy precipitate in the bottom of the bucket.

disgustipated Posted December 19, 2012 Report Share Posted December 19, 2012 it's not the water, or water conditions. i've had this problem in last house in glenfield now i'm in milford same thing. it only started 10 months ago, i've been keeping fish for around 5 years. also, my other fish are sweet, convict is super active and very colourful, jag is colouring up nicely, all other fish are acting normal. it's just that every now and then, one fish starts acting drunk and is dead within hours. sometimes the scales fall off them, sometimes nothing seems wrong with them. it's really quite frustrating.

brett2003 Posted December 20, 2012 Author Report Share Posted December 20, 2012 We're in the city centre (well, very near to it) so goodness knows what the water is like for us... I had a look at a Watercare report - the TDS ranges from about 70 - 170 depending on specifically which water source you draw from. Quote Link to comment Share on other sites More sharing options...
disgustipated Posted December 20, 2012 Report Share Posted December 20, 2012 so before i flush the carcass of the RTS that just died is there something i should look for? Quote Link to comment Share on other sites More sharing options...

blueether Posted December 20, 2012 Report Share Posted December 20, 2012 so before i flush the carcass of the RTS that just died is there something i should look for? Never flush a dead fish or for that matter any aquatics live or dead. Never. Quote Link to comment Share on other sites More sharing options...
#!CrunchBang Posted December 20, 2012 Report Share Posted December 20, 2012 Never flush a dead fish or for that matter any aquatics live or dead. Never. Yep, they just end up in the land fill and any disease could be release into the environment Quote Link to comment Share on other sites More sharing options...
F15hguy Posted December 20, 2012 Report Share Posted December 20, 2012 wow!!!! does your sink empty into the landfill??? :digH: (sorry couldn't resist) unfortunately most flushed stuff ends up in our waterways, best to chuck it on the garden, or used to lure neighborhood cats so they like you more than their owners Quote Link to comment Share on other sites More sharing options...
disgustipated Posted December 20, 2012 Report Share Posted December 20, 2012 i think you guys need to read up on the sewage treatment process before you go running your uneducated opinions all over the place. Quote Link to comment Share on other sites More sharing options...
Ira Posted December 20, 2012 Report Share Posted December 20, 2012 unfortunately most flushed stuff ends up in our waterways Only if there's a massive failure of the sewage system. My house especially would take a serious failure because it's a septic tank. Quote Link to comment Share on other sites More sharing options...

F15hguy Posted December 21, 2012 Report Share Posted December 21, 2012 Following UV disinfection the treated effluent is pumped 7 kilometres then it is distributed between two 4 hectare man made wetlands at Te Maunga before being pumped out to sea through a 3 kilometre pipe line which extends 950 metres off shore. This ocean discharge pipe handles both the effluent from Chapel St and Te Maunga wastewater treatment plants. although very hard for anything to survive through the treatment, Tauranga waste is eventually pumped into the sea Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted December 21, 2012 Report Share Posted December 21, 2012 Christchurch sewage is well treated before discharge to the sea but there was a prolonged period there of recent times where it took a short cut via the local rivers. It is also a slow and unpleasant death to throw a live fish into the toilet because it is not looking well. Quote Link to comment Share on other sites More sharing options...
disgustipated Posted December 21, 2012 Report Share Posted December 21, 2012 the RTS was well dead when i flushed it. i wouldn't ever flush a sick fish, it's quite cruel. plus i'd never miss the opportunity to kill something for good reasons. anyway, let's not get off topic. it seems that this mystery disease is widespread enough to cause concern. but it seems that nobody here can actually help much at all... possibly the wrong place to seek aquatic expertise.. maybe i should ask the staff at animates...
