API POND SIMPLY CLEAR Pond Water Clarifier 16-Ounce Bottle (248B)

Good option for the aquarium, seems to do what it says.

This stuff is the best, did the trick for my fish and me. I highly recommend it.

Clears the water in a few days. Love it

I have used almost all of the API products since we started keeping koi almost a decade ago. All the API products can be used together, if you have multiple issues. You need to be sure you are treating your problem with the right product at the correct dosage. That is why API has a product for every type of problem and explicit instructions. We have expanded several times, and we now have a 10,000-gallon pond. In our system we have a pump, filter, UV light, 2 bottom drains, a skimmer, and a sediment tank. I take water quality measurements every week, and occasionally issues will arise, even though we have a great system. By now you might be thinking I have stock in the API company, and maybe I should. I only recommend their products because this is what I have found works over trial and error.First, be sure you have the correct product for the problem. I have actually used this product once before, and thought it didn’t work. The reason it didn’t seem to work is I was not using the correct product for the problem at that time (this was in my early days in keeping koi). I needed API Ecofix (see my review if you are having issues with Nitrates and sludge), not Simply Clear. There is a subtle difference between the 2 products, and deciding which is best can be confusing as the descriptions use some of the same words. I’m using Simply Clear to clump particles and reduce the phosphate in the pond. I know the pond has a phosphate problem from testing the water. Definitely test the water before you put in a product, so you know how drastic your problem is at that moment.Second, no matter what product you are using, be sure to have an accurate measure of how much water you have in your pond and follow instructions for the correct dosage. Most people make mistakes in dosage because they don't know the volume of water in their pond. There are websites that help you calculate your pond volume that are easy to use. Many people don’t realize how the smallest increment of wrong dosage will negatively impact the results and possibly their fish.Third, use the product for the correctly length of time. Most products for your pond, no matter your problem, are not one and done. Using some products for fish is like humans taking antibiotics…you might need to dose more than once and finish out the entire length of time for dosage. This product requires you to dose your pond twice a week for two weeks until you get to the maintenance dose. You are building up a colony of beneficial bacteria with this product.Hopefully, reading this review is helpful to you and your fish. Feel free to ask me questions.

We have a lovely man-made waterfall and pond in our backyard that we worked hard to install and we love to sit by at night and play trivia by, but I have to admit it’s much nicer with clear water coming down and a clear pond as opposed to green slimy water is product keeps it that way, and I’m happy to use it instead of trying to keep slugs live in the Great Northwest where are you? Never know from minute to minute when it’s going to snow and I don’t want to torture, poor little slugs, in cold weather! I’d rather use this pet, safe animal, safe product that does the trick!

Did not help my new pond at all. No change in clarity.

I liked it because it did the job and the pond cleared up and has stayed clear for weeks. It may take a day or two but that's ok as long as it's not harmful to my fish. I have regular goldfish that my grandkids purchased 6 years ago. They are healthy and big now and I've always used the same clarifier. It works great.

This is not for algae--rather a cleaner only--but it really works. My pond feature was quite cloudy no matter what I used--but in a matter of a day or so Simply Clear had somehow "bonded" the contaminants together for entrapment in the filter--clear as can be and continues to be so with adding a bit each week.
