Use once per week
Use this all the time during spring and summer to remove algae and clear pond water. must be pro-active before algae gets out of hand but seriously approves water clarity and quality.

Makes it cloudy when adding-NORMAL
We have used this product for almost 2 years now. It will make a cloud form in the water when you use it, as shown in the video and pictures. This is normal. Your pond may look cloudy for the next 24 hours depending on the state of your pond water. (Do not apply more for 24 hours though.) Carefully follow the instructions on the bottle for measuring and usage. The directions are easy to follow. For our pond, I have to use half a cup. I use it once a week during cold seasons. During allergy seasons, rainy seasons (that cause murky water), and fall...we use it twice a week. You cannot rely on this alone to keep your pond maintained. This is only part of pond maintainence. This does not control algae or sludge. We like the product. Our only issue is that the bottle sizes are small for the cost. It seems most are costly though. Wish there was a more cost effective and economical product.

This stuff is amazing! <3
This stuff is awesome! I'd been struggling with murk in my pond, to the point I could barely see the fish when they were near the top. After 3 doses of the clarifier over 5 days, making sure to rinse my filters out each day, my water is beautiful! The before looks like I have ink in my pond, and the after is just stunning. The fish are perfectly healthy, and there's no funny smells. I'm so very happy about it and I'll definitely be buying again when needed.

Helped to cleared up my muddy cloudy pond! Didn't seem to affect the fish at all and was a decent sized bottle for the price!

Not sure what it is
I keep buying this and it’s very pricy and it never seems to work even though I follow directions to the letter which surprises me since their products are fantastic
