May have solved part of the problem

As you know I've been struggling with some mean GREEN water. The UV was not working. Today, I took my net off and got into the pond. There was a lot of decaying plant matter in the pond. Leaves that blew in, lily pads and flowers. I took out more than a bucket of 'stuff'. So I'm hoping that was the problem and not that I have too many fish. I don't think its the fish, I hadn't had any problems all along. The problems started after I netted the pond and stopped cleaning it really well with the net.

First off, I need some type of solution for the net that allows me access to net the bottom. Second, I can't believe I'm going to say this, but I am, I think I have too many lilies. I have the pots in milk crates so the fish don't tip them and maneuvering the net around the milk crates is getting more difficult as he pads spread out and I can't see clearly. So I had to get into the pond to net the bottom properly and parts of it were really bad.

It was so green this morning, I let out about 50% of the water before I got in so I could see a bit better. After my big clean up, I'm adding back in clean water and have the UV on. Fingers crossed that I got it at LEAST 70% cleaned and the UV can now do its job and the new water will speed things up.

I still haven't tested the well water for nitrates, but as I said, I use it in my tanks and smaller ponds and they are all fine, so I don't think its a water issue. I think this is a combo of UV light blew, net prevented me from cleaning properly, lilies are hiding the leaves.

I will update you tomorrow on if the UV has made a difference working on a mostly clean pond. I think I will get in tomorrow and move things around again and try scooping some more stuff out. Although I think I did a pretty good job today.

Any thoughts? Would all this 'stuff' cause my water to go green?

It would contribute, but proportionately decaying organic matter produces a small amount of Ammonia compared to fish.

I'm going to say yes. Any green matter left to rot on the bottom is going to cause algae. I don't know the mechanics but yes, gotta keep the pond clean. :) Glad you got all the gunk out.

Priscilla though you dont have to clean up for winter in the Caymans it relly doesnt mean you shouldn't may I suggest the probable best solution to this in that you buy yourself a pond Vac to help you take care of your ponds ?
Its and essencial piece of pond maintenance that you cant simply ignore and something that has to be done o a regular basis ?

Remember that your UV-C needs a regular once yearly change of bulb to help you in our fight against green water
