I used copper sulfate for algae control in my pond. I ended up killing all my koi. Is there any way to get the copper to dissipate or do I need to drain my pond to reintroduce koi?
Not that I know everything about koi, Andrea, but if the copper sulfate killed them, chances are pretty good it'll kill more of them. Clean your tank and start fresh, would be my advice. However, why not consult a professional? Perhaps someone at the place where you bought the fish and the copper sulfate?
I'd change the water, and flush the pond as well.
Will it help if I have certain types of stones like lime and sandstone in the pond? What would happen if I used salt water rather than regular city water to fill the pond? Please help!
First off, I applaud your intention to control algae without chemicals. It is not necessarily the easiest or most convenient fix, but most chemical solutions are only a temporary cure for the problem anyway.
There are several ways to keep algae under control in your pond without using chemicals. The key is finding which combinations of biological and physical components work best to keep your pond in balance. It may also take some time and patience to figure that out. It is not clear to me from your question whether your pond is stocked with fish, so disregard any of the following strategies that do not apply to your situation.
Also, don't be afraid to approach and compliment the successful pond owners you see. They'll probably be more than happy to share their secrets with you.
Sterile Carp is the only way I have found to control the algae problem in my pond. They have to be special ordered. I have two in my pond. ~Janette~
Plants, Floaters and Potted
Plants will soak up all those nutrients floating in the water that the algae also use to grow. The more plants you have the less nutrients in the water and no algae.
I use an algae control product in my pond that is very natural and easy to apply. It is environmentally friendly, safe on fish, pets, humans and plants. You can even swim in the pond.
Have them give you a free quote. I'm sure it will not cost much considering it is a very small pond!
I use Barley hay, you can buy it in bundles of all sorts of shapes and sizes. It floats at first which is great for the frogs to float on. Then it settles to bottom but continues to clean algae. It is said that barley hay was used in the old days for keeping algae controlled in water cisterns and wells.

I have used barley hay and there are some liquid products you can order but I have also just not treated it and after a few weeks, it takes care of itsself.
Is there a recipe for vinegar to use in backyard ponds with fish? The pond has algae on top. I want to kill the algae without killing fish. The algae is taking the oxygen away from the fish. Please help.
By Shirley from Little Rock, AR
I wouldn't use vinegar without checking with a reliable source. I had a fish pond for years with no problem. Do you have any plants in the pond? Water hyacinths are supposed to help. In the house, I have algae eaters in the aquarium.
I've seen products for sale called barley straw balls, which is supposed to deter the formation of the algae, so I would think you could try wheat or oat straw, if that's more readily available to you, but you should try to give it some sort of floating assistance, like tie on a sealed empty plastic bottle.
BTW, vinegar will change the pH of the water and could easily kill your fish.
I have a 7000 gallon fish pond with more than 70 Koi fish. I am faced with the problem of algae, and it is spreading very quickly. The walls of the fishpond are marble. One man advised me to put salt into the fish pond to control the algae. Is that true? Algaecide for fish ponds is very difficult to buy, and could not be found. How can I control the algae without damage to the fish?

Please go to this web site it will help you with your problem the web site is http://www.exoticwaterscapes.com/index.php
It will give all the information you need to understand and get rid of algae. Hope this helps
I have read that putting sterile carp in a fish pond will take care of algae. I dont think i would use salt tho. I put two in my pond I have on the farm where I live and it worked. No more algae. Go to a farm supply store and order one. I think one should do it. Hope this helps.
It's certainly a good idea to know how to get rid of the algae in your pond, but nothing beats designing for a good healthy ecosystem with the right combination of plants! Koi are tough on plants, but there are ways to protect the plants so they can take up the nutrients and compete with the algae.
...A pond without fish is like...well...the air without birds!
How can we balance our goldfish pond water with household products? We are thinking of products like baking soda, vinegar, muriatic acid, etc. We have a 6 foot x 27 foot pond. It is 1.5 feet deep at the shallow area with a 3 foot deep area. We have few water plants and full sun light. There is a homemade 30 gal. sand and gravel filter with a 3 foot to 4 foot long steam. From what we have read we have blooming algae (green water).

Get a UV light sterilizer, it will break up the algae. The water is run through the unit in which there is a UV light. It is perfectly safe for plants and fish, I run mine after my filther and pump and it works great, You can purchase a good unit for about $100.
Barley straw and barley straw liquid can be used. It will also go away on its own, If you go online there are many things to buy.
I moved into a new home and there is a 50 gallon pond in the front yard by front door! It has green algae along the walls. I bought a $50 filter and pump at Lowe's and it doesn't do the job. I have bought stuff to put in the water which also does not seem to help. I went to a pond nursery and ended up buying a PF 300 filter and am going to try to hook it up with the little pump I got at Lowe's. This filter cost me $150.
The pond is oval and has 2 shelves on either side with a deep center. I feel I am going round in circles to keep clean. Or do I have to! I have no fish as of yet, just one plant, (variegated Japanese iris). Do I need a filter of this magnitude or should I keep pouring in the chemicals (algae killers)?

I found this info on ehow.com. Hope it helps some....sounds interesting about the water lillies.
Algae control is an essential part of maintaining an outdoor fish pond, an environment commonly used to house koi. Because they are outside, these ponds are constantly exposed to sunlight and stray organic nutrients, both of which promote algal growth. One type of algae that's particularly annoying is green algae, which is composed of tiny, microscopic phytoplanktons that give the water an ugly, green tint. There are many chemical solutions sold in stores to help eliminate this problem, commonly called algaecides, but they can be potentially harmful to your fish if used improperly. Luckily, there's another, much easier and natural way to both eliminate and prevent green algae.
Things You'll Need
Using the hose, siphon about one-third of the water from your pond.
Refill the pond, making sure that the fresh water is about the same temperature of the water already in the pond.
Add the appropriate amount of dechlorinator. This amount should be specified on the product's packaging and is dependent on the amount of water you replaced.
Scatter water lilies across your pond until they cover about two-thrids of the surface. They will shield much light from reaching the water and also absorb many nutrients the algae would otherwise use to grow and spread. The green algae should gradually vanish within about two weeks.
Another reason for algae prevalence in ponds is due to rainwater carrying nutrients into the pond, which feeds the algae and allows it to propagate. To help prevent this occurrence, simply use a shovel and build a narrow trough around the perimeter of the pond. This will catch rainwater, preventing it from washing into your pond.
Be wary when using any of the dozens of chemicals available for eliminating algae. These products, if used improperly, can be hazardous to your fish. They also typically cause the algae to die very rapidly, which can cause a sudden depletion of oxygen, not to mention causing the bottom of your pond to be covered with a layer of dead algae. Thus, it's safer to simply allow the algae to dissipate naturally.

Putting some barley straw in a flow through bag will help keep the pond clean. It will not clean the pond, but if you put it in there after you clean it, it will help keep it clean. I"m not talking about using a huge amount, just a small handful in a bag should do the trick. I read about this on the Gardener's supply website.
My pond holds approx. 2000 lt. It has algae growing on the plants and fish in the pond. How can I safely get rid of the algae?
The best and safest to use is Sterile Carp Fish. I ordered mine from a feed store. In no time the algae will be gone. I have used so many products that didn't work at all. My pond is fairly big so I put in 3 of these fish. Oh one more thing, they are really reasonable in price. Hope this helps.
