Are these fresh water ? I have an outdoor fish pond and it has an algae problem. Thought these may help?

These are to be used with spring water and they only eat yeast and egg yolks. Your fish will only eat them.

Yes, daphnia are fresh water. They eat green water, so if it is a free floating algae, daphnia could help. Small fish will eat daphnia. For algae attached to rocks and other surfaces, snails will do a better job. Also a UV sterilizer does a great job clearing cloudy water, but may be pricey depending on water volume.

no, these are food grade / have had no problems at all. I would still boil and filter after sitting a long while anyway. as you fill, pour a couple caps of Bleach in with it

I notice that the water bowl area is yellowing or I just lift the filter out and check it, usually about once a week. You'll know from the muck that builds up on the filter. I've found that if the water is left running, the water tends to warm and that helps in forming algae. I would suggest the filter to be changed around a month if the water is not running constantly. We have our fountain on a timer so that it does not run at night.

I have a well so I just use plain water. I had the plants outside during the summer heat to germinate, then brought them in. They almost all germinated, but I have lost a few over the winter, probably because my house is colder and dryer than they would require. I do not spray them, and I believe that this could help, but the majority of them are still thriving anyway.

I agree with the other 2 answers in that algae must go through the filter to be killed. I would try some algae wafers also,they will soften up when soaked and can be broken up when dry for smaller portions. Hope you have continued success.

I would soak them in some treated water, such as Prime (Prime is the best). After you actually use them in the filter then be sure to use only tank water when rinsing them.

I don't see why not...they're just plastic....water shouldn't affect them...

Hi. I plan on using them in a "pondless" water feature. The grates will be placed over a water basin that holds the pump. River rocks will cover the grates. The water will flow into and onto the rocks, seemingly disappearing into the ground but will actually fall through the rocks/grates into the water basin, then be recirculated to the top of the stream/waterfall. Thus, there is no standing water, or pond. I hope that helps. :)

You need to give it some time. Mines took at least 3 weeks before I started seeing my pond clear up. No additional chemicals.

I am not sure there is a single answer to this, I have them on three tanks, and on two of them the algae growth isn't any worse than with any other light. On the third tank I need to clean the algae about once a month. The lights are great though, I love the way they bring out the colors in my African Cichlids. I guess I'd say, you're going to get algae with any light you put on, or just from sunlight if it hits your tank. These lights are no worse than any others.

I don't know about that I only use it in my pond. You might try contacting the manufacturer.

That is algae. You need a pond treatment to stop it. It is usually caused by hot weather and lots of sun on your pond. Pond bluing solution can help because it stops the sun from penetrating the water.

They seem to be, but I have not submerged one in water to find out for sure. Everything seems to stay fresh and dry, even when we run the swamp cooler for months on end.

Yes, water would be fine. I am sure that my grandson has taken these in the pool.

No, I would not just drop these in your tank. They are used inside the filter so beneficial bacteria will grow on them. If put correctly inside the filter, your tank will be much better off and will cycle much quicker, easier, and maintain good water conditions.

do not know that?it looks like the funky algae that is floating in the pond in the park down the street from my house. LOL I just wish this stuff was not so GROSS smelling and tasting

Yes, we have found these easy to clean. Just scrub with a clean toothbrush. Depending on water quality and use they last last for many years.
