View Full Version : Death of a pond

07-24-2008, 01:46 AM
I've had my pond up running since early May this year as I moved my goldfish out to have a dwarf cichlid tank. Everything ran smoothly till this morning. I walked outside before work to feed my fish when I saw them all floating at the surface. The water surface was a bit foamy and the all the dead fish had strange white film around them that i've never seen before. Now I tested the water and ammonia and nitrite were 0 and nitrate was a little over 10 since the pond was due for a monthly water change. The foamy surface made me immediatly think the water had been poisoned. For the pond to run so well for a few months then suddenly crash like that was very unusual. I asked all my family members questions like, "did you add water?" "did you wash anything in soap?" etc. so i've ruled out everyone in my house. So I probably will never find out what happened but if anyone has seen something that matches the symptoms of foamy water with a white film around the bodies please post. One last time here is my big oranda during better times, RIP.

I am so sorry for your loss!!!!!

That is so sad! I have heard about extra protein from uneaten fish food or rotting plants causing 'foam' in a pond, but neither of those would account for a sudden crash like that.

I have never really kept a pond before, so I can't be any more help than that, but I will look online and let you know if I see anything else.

Again, sorry.

that's a shame. Did you ask a neighbor if they did anything or saw anything. Do any frogs go in your pond?

I would look at kids in the neighborhood if they can get close to the pond sound almost like bleach or dish soap.

Real sorry for your loss.

Sorry to hear of your loss. I't bad enough when you loose fish like this but it drives you crazy when you don't know why.

how do you do a water change on a pond?

a bucket, a hose, some dechlor, and a good chunk of time.

That sucks,Ive seen pond wipe outs before but not with the symptoms you mention.Im sorry for your loss.Did you have a heat spell or thunderstorms lately?Big thunderstorms with nearby lighning can remove the oxygen from the water.

No it has actually been some of the most stable weather central Michigan has had in some weeks. A while back it seemed like there was a big storm every wo or three days for what seemed like forever. They were completely fine then. I have a suspicion that it was my neighbors children who did something, but i'm not about to go over and start accusing some children of killing my fish. I can't prove anything and while I do think they did it, all I have is my suspicions.

That would drive me crazy if I thought someone did that to me.Do you have a phosphate test kit?If your water is otherwise free of phos ,a high number in the pond could mean soap was added.

07-28-2008, 02:59 AM
I don't have a phosphate test but I'm still thinking it was soap. The surface isn't so foamy as it was a few days ago and one of the lily plants is looking a bit under the weather. It's going to become a fishless plant pond that my mom wanted since I don't have the heart to add anymore goldies into a potential death zone.

That's a real shame. I'm sorry to hear about this.
