Posted	Koi keep dying
23-07-2006 08:24 by belinda	Hi my brother has had a lot of problems with his pond after purchasing some ghost fish. He has been treating his koi for the last 4 weeks, hes treated them for white spot & also fungus, as one of his small koi died & it had whie fluffystuff around his eye. he got his water tested localy, & they advised its all ok. but he lost another koi yesterday & it was clear had no fungus on him. his pond is 4ft*3ft & 3ft deep. has anyone know what he can do. thanks
23-07-2006 09:36 by kell	Sounds bacterial, trying anti internal bacteria medication would be good, something is stressing the fish though, so he is going to have to look into what is causing it.
23-07-2006 09:51 by belinda	want do you mean stressing the fish. something in the pond, or could it be that my brothers garden backs on to a playng field. thanks for your help
23-07-2006 09:54 by kell	dont know what could be stressing them, is usually water quality or overcrowding or something like that.
23-07-2006 09:59 by belinda	ok, he only has 4 koi left at prescent. so i will get his water checked again. do you know what his water stats should be if we buy a testing kit. thanks
23-07-2006 10:10 by kell	sorry I cant be much help as I say someone more knowledgeble will be on today and should help you out.
23-07-2006 10:10 by kell	should be no amonia and no nitrIte, not sure what the nitrAte should be though, mine nitrAte on my tanks are 10. Someone more knowledgeble should be on today they will be able to help you more, you need to post more information though, like pond size, how long its been running, water parameters would be good info as well, it is definately worth buying testing kits and testing his own water. I would advise waterchanges, like something like 15% changes. Dont really know nothing about ponds but I think weekly waterchanges are needed.
23-07-2006 10:11 by kell	is the pond filtered?
23-07-2006 10:12 by belinda	thanks for your help he will aprreciate it.
23-07-2006 10:25 by Ray	Hi,what kind of pond pump is he using and what is the temperature,my pond was hitting 80 the other day,also the koi need to get out of the sun in a small pool so try to provide shade,really need to know the water params to advise though.
23-07-2006 12:44 by belinda	hi we got a hoselock filter, with uv. its a biolife pump 1800. we turn uv off while we treated the koi. ive got 2 hughe lillies & marigold. we will check temp of water later when my brothers home. what should we check
23-07-2006 14:06 by Danny Boy	this type of infection is almost always related to bad water conditions. maybe he has cleaned his filter in hose water rather than tap water recently?
23-07-2006 14:11 by keith t	ive got a packet of koi filter bugs for sale. ideal for adding essential bacteria to new ponds. last one up for grabs in my ebay shop JUNGLE-FISH also Pond parasite guard
23-07-2006 14:48 by belinda	hi keith, how muh are they. or whats the item number on ebay thanks
23-07-2006 14:52 by keith t	the filterbugs r £8 http://stores.ebay.co.uk/JUNGLE-FISH there are also various other pond treatments, hope this helps
23-07-2006 16:15 by wymcot	keith t - this is a forum, not a market place and your reply has little to do with the original question. It seems your only trying to sell a solution and not identify the problem.
23-07-2006 16:28 by wymcot	belinda- Kell asked a question about the water parameters, this information is very important. There's a lot of folks on here who can genuinely help with suggesting possible cures, but only once the problem can be identified. Also, the question about stocking levels is equally as important as it can have a significant effect on the water parameters
23-07-2006 16:44 by keith t	actually wymcot i was trying to help, if its a new pond with fish in it then it needs to get established quickly. and if im selling something that will help it why not offer them the product, they dont have to buy it now do they.
23-07-2006 16:58 by kevin george	fight fight
23-07-2006 17:18 by keith t	some people get right bees in there bonnett internet tough guys
23-07-2006 17:25 by kevin george	u said it advice is freely given and someone always nos it all proof is in the pudding
23-07-2006 18:27 by wymcot	Kevin T, OK point taken. Kevin G, amazing how youve interjeted into a thread that youve got no advise to give other than "butting in". There's "no proof in your pudding"
23-07-2006 18:29 by kevin george	how do u no they haveny got carp pox or it is due to ovedrstcking in the pond and as stressed the fish out due to lack of oxegean
23-07-2006 18:31 by kevin george	can always try adding air stone for extra oxygean to benefit the fish
23-07-2006 18:33 by kevin george	as far as advice goes my brothers kio had exactly the same thing and he had overstocked and hot weather lack of oxygean caused some to die off
23-07-2006 19:57 by wymcot	Kevin, read before getting on your high horse, heres a quote from my post "Also, the question about stocking levels is equally as important as it can have a significant effect on the water parameters"
23-07-2006 20:01 by kevin george	listen clearly kieth t was offering a solution and u didnt like his method of oferring something he nos will do the job,how many times have we been in fish shops and they try to sell us loadsa of chemicals saying it could be this or that he was just offering a solution like the rest of us
23-07-2006 20:07 by wymcot	Kevin G, again please read my thread "Kevin T, OK point taken". ie acceptance on my part I'd maybe gone a bit OTT with my remark However, if you must get involved, try coming up with some advise for Belindas quaestion instead of trying to jump down my throat over a comment that was not in any way or form, directed to you.
23-07-2006 20:12 by kevin george	look my brother was losing koi left right and centr in apond of 10x6x5deep iwas round there every other day taking out 2ft koi and putting em in bin bags and all this happened after introducing two new fish and water paremeters were all ok and it came down to lack of oxygene.i took dead fish to the shop and they examined em and tested water.i have no probs with u wymcott but it is a place of advice and everything needs to be taken seriously up to a certain point.
23-07-2006 20:26 by kell	my god what has happened here, like little girls honest to god.
23-07-2006 20:40 by wymcot	agree, end of story from this side
23-07-2006 20:46 by kell	well done mc.
23-07-2006 20:50 by keith t	one day wymcot wont be small fry and he will turn into a big fish
23-07-2006 21:09 by kevin george	mc what is a rapper now lol
23-07-2006 21:12 by robert.pope	sory to hear you brother is loosing fish ..... i would like to point out a earlyer comment by Danny Boy " maybe he has cleaned his filter in hose water rather than tap water recently?" surley filter should be washed through using pond water not hose or tap water! the new fish may have allready had infection from the shop! We had a similar thing with a very expencive fancy goldfish...cut along story short he infected our established fish.... we are still treating them now
23-07-2006 21:14 by Danny Boy	i think wymcot/mc deserves far more respect than he's given here. hes been posting useful hints and tips on this forum for ever! he is honest and has considerable knowledge. lets not loose yet another expert on this forum guys. they come very thin on the ground as it is already... chin up mc you are very appreciated fella
23-07-2006 21:15 by Danny Boy	robert i should explain that this comment was meant as a reason for the problem.
23-07-2006 21:38 by kevin george	everyone has an opinion and should be respected old and new members
23-07-2006 21:43 by Danny Boy	robert just read my own post and really did mess that one up... should read: " maybe he has cleaned his filter in hose water rather than POND water recently?" my bad
23-07-2006 23:14 by robert.pope	no problem danny boy ....i was only trying to make things clear for belinda... danny boy didnt mean to jump on you mate ! this forum has been a little hijaked
24-07-2006 00:04 by robert.pope	try looking on the practical fish keeping website i just have and found this news KHV to become notifiable disease here is the link http://www.practicalfishkeeping.co.uk/pfk/pages/item.php?news=1013
24-07-2006 08:17 by heros hero	If you suspect khv you should call environmental health to inspect the place you got the fish from. They have the power to shut places if khv is present until the stock is removed and/or destroyed and the entire system is disinfected. Washing filter mats with the hose is no problem at all, it is there for mechanical filtration, the plastic rings or whatever are the biological part and its these that should be rinsed in pond water. HTH
24-07-2006 09:50 by Alan	Flipping heck right back to the problem first off you say the dimensions are 4 x 3 x 3 to be frank this is small for a pond and to small for koi long term. If your dimensions given are correct you are looking at a volume of 225 imperial gallons. This is to small for even a single koi. As a minimum for 4 koi I would go with 750 gallons they are fish that produce an enormous amount of waste and equally have huge demands on oxygen levels and this I believe is where the problem lies. It is possible to over stock a pond with no problems but as soon as a filter clogs or the detritus builds up in the pond combined with very high temperatures as we have been experiencign over the last few weeks oxygen levels will plummet and this will ultimately kill the fish and there will be no outward signs of disease when oxygen depletion is the cause. Just to confirm this can you clarify how many fish were in the pond and the size of the fish that have died. I suspect it is the largest fish that have died as they have the biggest requirements in terms of oxygen. It is also possible that a virus has been brought into the pond with the ghost carp this won't necessarily by khv it could be something like spring veramia (although I am not familiar with this condition) there are many virus's that fish are susceptable to especially when the water temperatures will have sky rocketed. A good addition to a pond containing fish is a large airstone this will drive off CO2 and increase the surface area of the pond it should make a huge difference to the remaining inhabitants, it is also handy to have in the winter for preventing the pond from freezing as moving water has to much energy in it to freeze at the typical winter temperatures of this country.
26-07-2006 14:28 by belinda	hi all, thanks for all your advice. we have now brought a test kit, & his nitrate was high. Also his chloride was high. we have done a 50 % water change. he did also cleah his filter with tap water which he will no longer do. Just use the pond water. Thanks again
26-07-2006 15:00 by drummerduck	salt bath every fish 3 oz to 2 gallons.
27-07-2006 14:57 by Linda Chenapa	Lots of people I know are losing fish, due mainly to the heat, resulting in low oxygen. You need an air stone in your filter as well as the pond. The bacteria need it just as much as the fish. At the end of the day you don't keep fish, you keep water, get that right and the rest should follow. Best of luck.
27-07-2006 15:44 by Alan	So true linda many reef keepers could learn from that pearl of wisdom. Glad your back you haven't been on here for ages.
27-07-2006 20:55 by Linda Chenapa	Alan - on 6 weeks holiday! Been very busy with school work plus just built another pond.
