I just walked the dog at the Foster's Mill "fountain ponds". The fish are all dead in the larger pond, the one where people often fish. They've floated to the top. Some are scattered around and look like white spots from afar. On the far corner, there are around 500 dead fish all accumulated. The smell is bad. Lived here for 15 years and haven't seen this before. Anyone know what happened? 

Maybe it's too hot for them. 

Heat causes less available oxygen. 

Oh dear. If white spots, it could have been a disease like Ick. Are the fountains running to help with aeration and heat?? 

The fish don't have white spots. It's that they're belly up that they look like white spots from a distance. Just drove by again. They're all spread out now. Really nasty looking. 

That's a lot of fish in not that big of a pond. If not disease, then I blame the heat and not enough aeration or filtration. Sad.

The fountains in my pond overheat just being in the sun. I have to submerge it deeper to keep it cool. 

A few years ago I had goldfish jump out of my pond because the water got too hot! 

Combo of heat and maybe fertilizer runoff from golf course- most likely heat . Fish like pretty narrow temp zones. My pool is sitting at 95- too hot for fish.I don't even bother with an outside goldfish pond here- every time I do the die off in Aug 

Yikes....my fish!!!! :( 

SighFi-get an aquarium and bring them inside till Sept. we did that for a year or 2. I just had too hard of a time keeping the outside ponds in balance in the summer. Algae blooms are bad here and hard to get rid of- even in the shade. 

My goldfish ponds stay cold. I keep them filled and do some (probably not enough) water changes. Lately with the heat that means filling then every 3 days or so. I keep the fountains fast andbubbly for aeration.They are not exactly pretty but they are squirting upwards nice and tall. They only get morning sun though. String algae is about all I get and that's not a real problem as it is in one o the corners. I have water snails and the fish to eat algae off the sides. But my ponds aren't full of fish either. 1" of fish per gallon is the general rule. They stay there winter (Hibernating) and the rest of the year. I think the plants help as well. 

Mine are ok. I have a deep pond and it's all shaded. The water is still cool to the touch.

I passed the FM pond just now. Omg does it stink, lol. But the vultures and birds are picking them out and eating them. so nature is dealing with it. Don't know if the HOA plan an cleaning it themselves. Or who would that chore fall on??
