What';s this all about?
I've taken the power washer and cleaned it off the boulders and rocks that are directly in front of the waterfall.
I also have some ECOBLAST, that is supposed to get rid of "debris" in the pond.....I'm guessing that means algae.
Will this stuff harm either the fish, or the plants?

And if I use if will it clog the filters with all the "debris" and should I clean them?

Thanks in advance
This thread may be old, but the subject will continue to be relevant as long as people own ponds and water features. That subject being---ALGAE. It has been around for millions of years and, regardless of man's ingenuity, it ain't going away.

Did you have the algae before you went on your boat trip? Brown algae is extremely rare in freshwater. I would suspect that either the algae is dying or it is just coated with sediment/silt giving it a dirty appearance. Algae, because it is living organisms, in particular... mini-plants, will not proliferate unless it has a good supply of nutrition. The higher the chronic nutrient levels are in a particular body of water, the higher will be the incidence of algae proliferation. A certain level of algae is both acceptable and desired.

Control the nutrient levels and you will control algae growth. Sufficient aquatic plantings should keep the NitrAte levels too low to promote most algae growth. Attention should also be given to the level of Phosphorus which is also a plant nutrient and commonly overlooked. Any P level greater than 5 ppm will encourage rampant growth of some specie of algae, most particularly 'String Algae, which absolutely thrives in warm moving water high in Phosphorus.

I am not going to address in depth the use of ionizers or ultrasonic devices nor the use of chemical or enzyme based products for direct algae control as NO studies have been conducted on the long term physiological effects these products may have on fish or other aquatic life. Others may disagree, but most of these products are 'Snake Oil' at worse or misrepresented with half-truths at best.

Yes, you should clean the filter pads, not the filter media, in both the skimmer and the biofalls unit as often as needed. They are performing the function that is intended...filtering.

Any truth to using Barley hay to get rid of algae? My bro has a nice koi pond full of green algae, has a pump in the pool pumping water to a stone fall above the pond. The algae was killing his pumps, so I put window screen around the water pump to keep it from getting clogged up. He has to wash the algae off the screen daily or it won't pump water.

Barley hay, when it decomposes, supposedly releases an enzyme that breaks the cellular wall of certain species of algae. Note the word 'certain'. I, personally have not seen any positive results from its use. And you have to keep in mind that, when it decomposes, it adds MORE nutrients to the water column.

Where in NW Florida are you? I am in P'cola.

This contains a major typo on my part. This should read "Any P level greater than 0.05 ppm will........"

So much for multi-tasking at my age.
