Pond Boss Forums MANAGING AN EXISTING POND Fertilization New Pond owner - Question about Cutrine

I recently purchase a home with a ½ acre pond (10 ft. deep in middle). No moving water, no aeration. Pond has been in place for about 15 years. Bass and Bluegill, pond is in good condition.

The guy I bought the place from left me some Shoreline + for controlling the lilly pads and cattails. He also left some Cutrine + grannuals. He said he would use the Cutrine to keep the weeds at bay.

There does not seem to be an algae/weed problem, however, should I use the Cutrine as a preventive step? Kind of like chlorine in the pool before it gets green?

Well weeds as he is calling them can come in all kinds of forms... Cutrine granules though are more of an Algaecide killer. You know that green slime on the bottom and top that form into mats Cutrine is good for that and it's also good for Chara which he may be mistaking for a weed. Chara can grow and have a real musky smell to it and it looks like carpet coming up from the bottom of the pond but its still an Algae not a weed. 30 pounds treats a half acre but without air in my pond I would be careful as to how much you use at one time. I would do a part of the pond and then wait a few days to a week and do another part. There ia a lot out here on Cutrine so do some reading out here and you will find your answers for sure!! Some Chara I think is good in a pond as it helps smaller fish have a place to hide and grow but to much can really not be fun to fish in.

Welcome to the forum!

No, Cutrine granules are only used as a treatment, not a preventative. Cutrine only treats algae, not vascular plants.

When we moved in last fall, there was a big mat floating on one end of the pond. The guy we bought from said it was "pond turnover". It was mostly just a big matt of muck.
The bottom of the pond is very mucky.
However, I don't want to mess up a realtively good pond. Last fall I just used the ShoreKlear to keep the lilly pads and cattails down.

The lily pads look beautiful, and they provide excellent cover for bass to prey on forage fish. I would trim the lilies with care.

Do you plan on eating any fish from your pond? If you do, then you may want to read all of the ingredients for any chemicals you place in or near your pond.

The lilies look good, and from here they look like Hardy lilies, which don't spread fast.

Both chemicals that you have are safe to use in ponds where fish are consumed provided that they are applied according to the label.

I agree the lilies do look good! I wish I had a few but my pond is fairly shallow and I am afraid they would spread like wild fire! I sometimes wish I had the immediate 2 to 3 foot drop off like some folks have. I would for sure have some then!
