This is good product I use for the spring startup of my back yard pond and waterfall. It clears the water up within a day. It takes very little product to achieve the desired results

it's all a lie. It doesn't work and when you ask why they will simply tell you that you didn't use it in concert with their other product line. If you have green algae, empty your pond completely of water, fish and scrub every rock with bleach. Rinse and re-assemble. Then and only then, you might have a chance. They even told me to permanently bag my UV light. You would usually leave it off until positive algae is established, then turn it on. BUT NO PRODUCT IS GOING TO STOP GREEN ALGI !! IT MUST BE PHYSICALLY REMOVED FIRST. I have had better luck with pond max products but they have a more sensitive temperature threshold.

Product certainly seemed to help clarify pond but I also introduced a uv light at the same time so they may well have worked together.

It really didn't work as well as the advertising claimed. I was so hopeful and I also get my pond professionally serviced twice a year. All I was expecting was a little additional help over and above the weekly additives and regular skimmer cleanouts done as required. I think I will just stick to what I had been using as this product only seemed to be money down the drain.

This stuff really works miracles. We struggled with string algae for years in our 1600 gal goldfish pond. We had a good pump, filter with U/V etc. but nothing seemed to help. About 4 years ago we started with Nualgi and in a couple of weeks string algae just about disappeared and the pond was crystal clear. Since then we just squirt in a maintenance dose and thats it! I really can't say enough good things about Nualgi. FIsh are healthy, froggies always seem to find a place to hang out and no more nuisance algae. The UV light stopped working last year and we did not bother to replace it.

I’ve been using the Nualgi Pond products for the past two years with fantastic results. I highly recommended Nualgi.

I received a new fresh bottle of Nualgi on July 2, 2023...today my pond is crystal clear again. I had used Nualgi back in 2018 to clear up a terrible algae bloom I couldn't get rid of. I fead reviews on Nualgi back then, ordered it and I had a crystal clear pond within 2-3 weeks, as I recall. This year I started my pond up mid June as had been so cold in the spring...then it got terribly hot right after and I had pea soup in my pond right away. It was so green you couldn't see the poor little goldfish. I tried everything including a complete water change and vacuum of the interior; and, I had pea soup again in a couple days. Nothing I had on had would clear it up (I had thrown out my old Nualgi as figured it was old). Ordered a fresh bottle of Nualgi on July 1, and now, 8 days later, I have a crystal clear pond for the 1st time this year. Thank you Nualgi. I love this stuff...just have a little patience...it sure has worked for my little 100 gal pond.

Took a whole month, then BAM! All clear. Amazing. Tried this after beneficial bacteria we were using (Microbe Lift) was helping but not completely keeping things under control. We started using this in conjunction with it, and only needed 2 drops each week for our pond size. We had our doubts the first few weeks because our pond did NOT clear up fast like some reviewers said. It took the full 4 weeks. But once it got clear, it has stayed clear. I can’t believe I spent good money on a tiny bottle of what is basically fancy pond water with super special algae in it, but yes, it is worth it. Our pond is a 165 gallon plastic insert that already had marginal plants, snails and mosquito fish, which was clear, then got gradually worse over the summer. This cleared it up even in the full sun and heat.
