jn Posted March 6, 2011 Report Share Posted March 6, 2011 Hi all, Have a property in the CBD which was evacuated the day after the quake. Had some liquefaction and the tenants said the pond was leaking when they left. Don't know from where, bottom or sides (its concrete and the courtyard is a mess apparently). Anyway.. point is if there is any water left and fish are still alive I will need to work out somewhere to hold them. How do I safely dechlorinate a larger quantity of water? I know this is a coldwater/pond type topic but being chlorine related I thought it would apply here as well and have a better chance of being seen. I've very fond of those fish and I sure hope they made it through. We're in zone 3, so not accessible till at least middle of the week :tears: Quote Link to comment Share on other sites More sharing options...
Windsparrow Posted March 6, 2011 Report Share Posted March 6, 2011 You can leave water with a open lid and Chlorine will dissipate into the atmosphere, although chloramines will still be present(Which tends to be more lethal) Ideally go to a lfs and buy some stresscoat / prime / pond grade dechlorinator. Stresscoat 5ml per 38L, Prime 5ml per 200L. Pond stuff ranges. Just use the product on the new water 10 or so mins before acclimation. If you're putting them into a temporary home, look into filtration if you haven't already. Very important. Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted March 6, 2011 Report Share Posted March 6, 2011 You can use sodium thiosulphate at 3 grams per 100 litres if you know how much water you need to treat. It will take care of chlorine and chloramines. If you cannot get hold of any and you know how much water you want to treat, send me a PM and I can give you some.

new zealand discus man Posted March 6, 2011 Report Share Posted March 6, 2011 sodium thiosulphate..Chemist shop called .hypo of memory. Used to remove clor when developing films...Phill Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted March 6, 2011 Report Share Posted March 6, 2011 That is the one. It may not be cheap rom a chemist as it would probably be analar grade. Quote Link to comment Share on other sites More sharing options...
henward Posted March 6, 2011 Report Share Posted March 6, 2011 SEACHEM PRIME the best and msot costeffective way of treating aquarium water 1 capful will treat 200L!! huge! i doubt you will have more than 200L of water in a bucket, thats a huge amount of water but none the less, a small bottle can treat a couple of thousands of litres.

new zealand discus man Posted March 6, 2011 Report Share Posted March 6, 2011 That is the one. It may not be cheap rom a chemist as it would probably be analar grade. It was just a few dollars for 500 gms of crystals.treats thousands of L ....P: Quote Link to comment Share on other sites More sharing options...
DonnaM Posted March 6, 2011 Report Share Posted March 6, 2011 You can throw them in one of my empty turtle ponds for a temporary home. I have someone who tops them up with artesian well water as needed so no problem with chlorine. Quote Link to comment Share on other sites More sharing options...
jn Posted March 6, 2011 Author Report Share Posted March 6, 2011 Thanks everyone. That's extremely helpful. So i have a couple days to source some stuff in the hopes that i have some fish to re-home. Will post an update once I know if they're ok! Quote Link to comment Share on other sites More sharing options...
new zealand discus man Posted March 6, 2011 Report Share Posted March 6, 2011 When filling make the water blast the surface and most clorine used is a gas not powder so by blasting surface it will help to release a lot...Let air bubbles settle for 30 min so not hypo-oxygenated....Phill Quote Link to comment Share on other sites More sharing options...
new zealand discus man Posted March 7, 2011 Report Share Posted March 7, 2011 Just remembered dont have them released into really cold water as that temp drop can kill..Yes even a goldfish...Phill Quote Link to comment Share on other sites More sharing options...
jn Posted March 7, 2011 Author Report Share Posted March 7, 2011 Damn. Bad news, building is red-stickered not so much because of its own state, but due to there being some potentially-unstable buildings that are too close for comfort. The possible good (OH!! Big AFTERSHOCK!) news is that our body corp secretary got to go along with the inspectors who were doing the assessment, and when we asked him if there was any water left in the pond he said he though there was. Not 100% sure, but I dare say if it was completely empty that probably would have been obvious, so with a bit of luck they might still be ok (mind you we did have a good lot of rain yesterday so it could have been rainwater that hadn't drained awsay yet!). Hmm.. I think I've just taken the gloss off what I though might have been a bit of good luck.. Guess it'll be at least another week before I know. Still feeling very thankful that this is the worst of what's worrying me! Time to source a big enough temporary pond. I've wanted to have one anyway (for example would have been useful for a case of whitespot I had to treat a short while back) so there's no time like the present. ps: when I do collect them, I'll take them away in as much of their existing water as possible and acclimatise them gradually as usual. With a bit of luck I'll get something soon and fill it, dechlorinate it and let it sit at ambient temps for a few days, so the water might be as closer in temp to their current situation.

Jennifer Posted March 7, 2011 Report Share Posted March 7, 2011 That aftershock was pretty impressive. Shout out if you need a hand with anything. Quote Link to comment Share on other sites More sharing options...
suphew Posted March 7, 2011 Report Share Posted March 7, 2011 There's not much point trying to take old water, it will just be dirty old water and water doesn't hold very much of the bacteria you need. Moving them will be no different to doing a pond clean out or when you take fish home from the LFS. Plastic kids paddling pools make good temp ponds Quote Link to comment Share on other sites More sharing options...
jn Posted March 7, 2011 Author Report Share Posted March 7, 2011 Taking some old water is more about just letting them adjust to a new temp/ph a little more gradually then dropping them into a totally new environment. If I half fill some buckets with old water I can slowly add new water to that and let them adjust before putting them in a new 'home'. I'll grab some of the large potted pond plants for some nitrifying bacteria. I have a filter in there but I dont think I'll be able to conveniently operate a pump on a temporary setup at home so i think some of the plants will have to do. I'll settle for a paddling pond if I have to but have my eye on something deeper (some of the fish are probably 7 years old and quite big). I have 6 cats and am also not likely to be able to easily shade the pool, so dont want them being 'hooked' or 'cooked'. Quote Link to comment Share on other sites More sharing options...
