Well, I'm not an expert, but I can tell you this - those are both signs of an excess of nutrients in your pond. Foam means phosphates are high so you probably have an excess of organic material decomposing in the pond. But remember that these are both symptoms - they are not problems in and of themselves. Identify and address the cause and the symptoms will disappear.

More information would be helpful - how big is the pond? How old? What kind of filtration?

Hey- thanks for reply. This is the pond in pic. Seems to dissipate a lot after rain however- it comes back. Pond is about 2 months old. Have a bio filter and added microbe lift for first two weeks to get things going.

String algae at 2 months ? That's crazy how much do you feed your fish and how often for that matter what food are you using

Hi. I feed them morning and night and use koi pellets that were sold to me from the Breeder. It’s good quality.was sold this today at store to help control froth. Anyone ever use this?

Do you have city water or well water? Not that you can do anything about it but well water can be a real problem to deal with.

How many gallons is your pond? 7 koi of what size?

I don't know why they sold you this dry bacteria product for foam - maybe the theory is the bacteria will help break down organic matter? It appears that your pond is relatively new and you don't have a lot of plants growing yet - I would just give things time to settle down and stop adding anything at this point.

also, the above microbial algae control is a liquid. Guy said defoamer is a temporary band aid to break up surface tension. Said wants to get at root of prob. and felt this should help.

Agree with @Lisak1 , Let things settle. I would add alot more plants to the pond, as well. The plants will help balance the pond and lessen the severity of the pond cycling.
