Okay, here the deal. We dug our pond out in 99 and since then we have NEVER had this much alge. The entire pond is not alge green! Normally a little bit of calcium cloride does the trick, but this time it isnt, so we got a lot of it out this last week. Then it rained yesterday and its back to the whole thing being green. Anyone know of anything that will work to get rid of this?

 

You could try copper sulfate. That's what's used in water treatment to kill off algal blooms like you're describing.

 

Something is out of balance! Maybe a fountain will help to aerate it and keep the Oxygen level high, If you have too much CO2 dissolved the plants will thrive, Algae is a plant life and requires co2 to grow. Remember oxygen is poisonous to most forms of life on this planet!!! Even a small fountain could help keep the water moving and O2 level up. Do you have any fish in this pond? Armor catfish will eat the algae and they go for upwards of $3.00 a pound last time I checked, they multiply like crazy!! My friend cast netted over a hundred of them in ONE throw in his small pond!! I don't know if they will grow in your area, but you might make some money on the side if they do!!

 

We have catfish and bass in there. Im just confused on why this year it got really bad, and in the fall is even more confusing??? We have a pump in there also. Ill have to see if we tried the calcuim chloride this time or not. THere is so much stuff we've tried...

 

You owe me a new flat panel monitor!!! I tried killing that bug!! Is the pump for a fountain or just water movement? When you pulled out the bottom you probably took out some of the good microorganisms from the bottom muck. Now it is out of balance in micro organisms, You might want to find a clear pond and take acouple of five gallon buckets of the bottom sediment to about 5 inches deep!! You want to get those good guys in your pond. Treat the cause instead of the symptoms. Or else you will be forever adding chemicals to get it to appear okay!!

 

Its a sump pump, with a piece of pipe angled 45* with a cap with holes drilled in it to shot water out.

So I should go to a clean pond and dig out the bottom and fill the buckets with the muck i pull out? It seems to make sence.

 

How much rain have you had this year? We have a small pond and have had very little rain. It is the clearest it has ever been.

 

Barley Straw is what we are using in MN with pretty good results.

How deep is your pond? I believe depths less than three feet are most susceptible to it. Any fertilizer runoff? Fertilizers especially those containing high amounts of phosphorous will contribute to it. Sterile grass carp sometimes help cut down on algae but with varying success. I would not rely on the carp to get rid of it. I would use them as more a preventative measure in the future. 5-10 per acre is the norm I think.

 

Yeah take a few five gallon buckets of muck from a clean lake and hopefully you get the good bugs and enzymes and they populate your lake!! Try to get a different bucket from the differing depths and place the mud at the same depths in your lake, just in case they don't like too much sun or versa vice!! Say a bucket full from shore, abucket full from 3 foot, a bucket from 5 foot, so the conditions match what they are used to!!

 

There is a company that will UPS products for lake/pond weeds etc.
I've ordered from them. Aquacide Co.
web site is www.killlakeweeds.com
I believe the product you want is called Cutrine.
Check them out.
I've used the Aquacide pellets for my beach at the cabin.
They send out quick and are relatively inexpensive.

I would have to vote on some type of aeration. That would be a long term solution. Since you already have power there for the pump, it wouldn't be a big deal to install. I don't know how much they cost though. If you do have fertilizer runoff, that could be aggravating the situation with all of the phosphorous and nitrogen that they contain.

 

Ph test kits are cheap go to an aquarium store. I would check the ph in your pond and the ph in a clear pond in your area. Don't underestimate the affect of ph on the quality of water. How is the health of the fish any sores or anything?
