APIPond-Zyme Sludge Destroyer Pond Water Cleaner With Barley 454-Gram Container

after trying other products I was doubtful about Pond Zyme, but it really has worked for me. Before using it my pump was clogging weekly with dead blanket weed, now a month later the pumps still running at full power and I have a clear pond.

The product arrived labelled sludge remover but as we had had so much trouble even finding Pond zyme plus in Britain we decided to give it a go anyway. It has certainly made made a difference to the pond weed accumulating but I wish I knew whether this is the same stuff we used previously ie pond zyme plus.

Really pleased with this product.Makes life easier 😉

I was disappointed with this product as it does not deliver the clarity of water that I was led to anticipate.

I popped some of this in my pond a week ago and it went to work straight away. The water is crystal clear and I am beginning to see the actual liner of the pond. The addition of barley extract is an added bonus as it has halted the spread of the dreaded blanket weed. The fish seem to be unaffected in any way and it's a real pleasure to see them all the way to the bottom feeding. The amount in the container will be sufficient for quite some time and is good value for what I paid. Overall it's a great sludge gulper that works fast.

I had algae sludge stuck around the pond weed which I couldn't remove without disturbing the wildlife (damsel fly eggs and baby newts) so I used Api Pond-Zyme scattered onto it twice a week for 2 weeks and it disappeared. I am delighted with the results.

Used up the whole tub.... had absolutely no effect. Would have been better to just throw the money in the pond!

I used to use this in our pond with two fish and it did seem to help the water quality.I have since moved and this house has a pond with 14 fish and I tried this at first and again I could at least see the fish but in the end had to install a full pond filtration system.

The media could not be loaded. Our pond started getting green (like the fish could barely see 😔) from too much fish waste. Even when cleaning the filter often, we couldn’t keep up. Used a small amount and it cleared up within a day. Love being able to see their happy orange selves again ☺️

I use this and the algae fix and between the two I have noticed a huge improvement. This more than the algaecide definitely. I’ve had the pond 10 years and this is the first year the algae is actually slowly coming off the sides and bottom. It’s literally a 7 x 15’ concrete hole in the ground next to the front door with a waterfall and fountain. It’s gorgeous and I put a lot of effort into keeping up with the algae. I have probably 100 fish in there so between uneaten food and waste.. the algae and buildup around the ornaments is just nuts. I mean I could probably get away with less upkeep, but I enjoy interacting with the bigger cichlids and it’s a nice quiet time for me. The ornaments always get caked with algae no matter what. And the rocks and waterfall, too. This doesn’t really help that thick black algae that builds up on the rocks. API makes a waterfall oxi powder but i’m too scared to use it bc i’ve seen reviews saying all their fish died. I may get it and use it on smaller rocks outside of the pond but not in it. Anyway this mainly just keeps the floor and side walls clean. Water too obviously but knock on wood the water has been consistently clean for quite a few years. I’m pretty much just referring to the constant fish waste and algae buildup around the ornaments and in general. I’ve noticed im starting to actually see the cement instead of one thick green blanket up to the water line. The plecos are starting to eat more fish food bc of the significantly lower algae count. Overall i’ve noticed a huge reduction in algae since adding this to my pond maintenance schedule. It’s June now so i’m sprinkling a little bit in every other day and algaefix every 3 days. I’m in Florida and this will probably go on till October when the heat and sun let up a bit. But this is huge volume and the first tub lasted almost a whole year of constant use. Good stuff.

Quick shipping thanks for the product I needed

This product just did not deliver what it promised i.e. a clean pond. It is totally ineffective and waste of money. All claims made for the product are false. Extremely unhappy and feel cheated of my money. Would never buy it ever again.

Very good, did on excellent job on my swimming pool converted to koi pond ( still 5' deep) very happy with this product
