I think it looks more like dirt then mulch. We just spread a truck load of dk brown dyed mulch around our pond, and the last two days it's been so windy that tons of it has blown into the pond, being sucked into my new skimmer (so glad I bought that thing!). And my water isn't the color of yours. I have a lot of dirt that has settled on the rocks in my pond (I think this was the pieces of mulch dust and tiny pieces to small to float, and the water has a slightly brownish tint to it. It is still crystal clear though and I can see the bottom and the fish very clearly. Now before the mulch when we would get winds like this my pond would look like yours does. That was dirt blowing in. Since the rebuild, all the the gravel in my bog has been wonderful for clearing up the dirt within a few hours to a day depending on how bad it is. Before the rebuild though my homemade skippy type filter didn't have a prayer for cleaning that out and I would use the quilt batting. Also I know a lot of people here frown upon additives, but I have used the coagulators (AccuClear) and they do help, especially if you combine them with the batting. I've also heard amazing things about Microbe-Lift products. I really would try those things if you really have no way right now to try to fix whatever is wrong, patience is not a virtue of mine. Kuddos to you doing all this with morning sickness, cause I absolutely could not imagine doing any of the work ponding has entailed when I was sick and pregnant with my twins. I think I would have died.
Here is a pic of my water with 2 days worth of fresh dyed mulch getting blown in. It's still super windy, you can see the waves some in the pic and some of the blur is due to that motion and my camera, not the clarity of my water.
