How do I get rid of the never ending algae in our pond?

Since spring I have been battling 2 kinds of algae in the pond.. The string algae and the common slimy stuff. I rake it out every two weeks. I have used the recommended citrine and algeacide but to no avail. This pond is 100' X 50' X 8 foot deep. It has both a waterfall and a bubblier for aeration. I know that it has been a hot dry summer in Mi. but it seems like a losing battle. Has anyone got any suggestions that I might not have tried? It also has fish , turtles and lots of frogs so anything I use has to be earth friendly? .

    ORGANIC ALGAE REMOVAL METHOD!!

    You'll need one or two square bales of barley straw, cut the twine off the bale of straw & stuff it into an old pair of nylons, or fine mesh netting that can be sewn shut. (I've found mesh bags with string to tighten and close them at the dollar store 4 bags for a dollar, they work great for this.) Next, place the 'straw filters' in the pond in several areas. The straw will work like a filter, great because it is all natural but a very effective way to rid your pond of algae.

    It is important the baler twine is cut off the bale to allow circulation around the straw, thus better filtration. The netting or nylon contains the straw, keeping it from plugging your pond equipment. The straw works like a filter to rid your pond of algae. Because of the size of your pond, you may

    want to place the straw filters in several places. Using this method you will usually see algae clear

    up in about 2-3 weeks.

    Here in Western Canada, we have used this to clear up our ponds during hot summers, Ranchers place large round straw bales directly in ponds to clear algae out of ponds for their cattle.

    Algae spores will blow into your pool, where they are supported by temperature, humidity, ideal pH levels and sunlight.

    Have you considered controlling the pH levels in your pond like you would a pool, but without using the same harsh chemicals? You will need a pH kit, just like the ones used for pools.

    An ideal pH level for an outdoor water pond or garden is around level 7.2, the low end of the pH range. This level can help control the growth of algae.

    A pH level is the measurement of how acidic or alkaline a water body is. Maintaining adequate water circulation and proper filtration will also deter the growth of algae.

    I hope you have a membership to a big warehouse type of club like, Sam's, BJ's, etc. You need to purchase those big jugs of Vinegar and some big boxes of Baking Soda. Using these basic ingredients to adjust the pH level of your pond. Vinegar to make more Acid, and Baking Soda to make the pH more alkaline. Using the pool kit water tester, or a pH meter will help you know which product to add or not add to get the pH level needed.

    You can also do your own web site research on pH and algae, to help you understand how to control it better. Good Luck

    Also,to control algae, don’t add more fish than your size pond and filter can support. This will cause algae to multiply quickly. Avoid overfeeding the fish, as this is also a common cause.
