Hey Sandy (nice to see the name of someone I recognize!) No I feed my fish twice a day in a small feeding ring. My father and sister in law both have fish (lots of them in what I consider very small ponds) that they don't feed. Only reason I feed the fish is that my pond is so big with so many places for them to hide that unless I tempt them to come up to the feeding ring I never even catch sight of them (and then get anxious that they have died) and so like to see them at least once a day just to be sure they are okay! At any rate I am just baffled by the foam - there is virtually no pond debris to speak of (that I can find anyhow - no leaves, acorns, decaying plant matter etc.) but I live under a dense canopy of mature hardwood trees and we have just completed our rather horrible yearly gypsy moth cycle and not to be too gross about this but when the gypsy moths are up in the trees munching on the leaves it virtually rains gypsy moth feces for a few weeks (it is so bad that at night when the feces is dropping out of the trees it hits the leaves of the trees and makes a patter so loud that you think it is actually raining!) At any rate, whilst I can blow this crap off of the decks and sweep the paths etc. I cannot control it falling into the pond (where it dissolves as soon as it hits the water) so now I'm wondering if this crap falling from the sky could be the culprit? I mean it's not like I've never had any foam before, but I've never had this much and for this long. Guess I'll just increase my filtration and continue the daily water changes... I would so love to drain the pond and scrub it and re-fill but I can't catch the fish...sigh...how does one catch such small fish in a large pond anyhow???

Often times the foam is a sign of too much decaying organic stuff in the pond. It usually isn't anything dangerous, I believe activated carbon is good for that which you can get at any pet store in the aquarium section. (Any seconds on the carbon, can't remember for sure?) Fish wise keep an eye on them, are they doing it all the time? It could mean a ton of different things, swim bladder infection is the first thing to come to mind. There are lots of treatments for different things, Melafix, Pimafix, salt treatments. Without knowing more you can't diagnose easily. Do they flash (scrape their sides on rocks), or have red behind the gills, any thing else? I'm not a fish expert but thats what my koi guy always asks me. Good Luck.

You might try setting out a few jars around the pond with small holes punched in the lid and filled with vinegar and a tablespoon or so of Dawn dish detergent. They love vinegar and will crawl into the jar and can't get back out and the Dawn will kill them when they eat it. They will breed in any moist organic material in your yard so putting jars around those areas might help decimate the population. Linda

I just posted a similar complaint - one problem is simply incompatibility between different manufacturers, AND between pond products and those made for irrigation and plumbing. Theres a point where it just wont fit - Ive tried to force it only to have the tube split. In that instance I just said to heck with it, and attached the tube directly onto the threaded outflow port and clamping it on with a clamp. It all seems to be trial and error -lf barbs dont fit, try fittings with threads instead of barbed ends - seemed to be a slightly smaller diameter . with clamps I think that may be secure enough.
