API POND-ZYME

Have used this product all the time does seem to help in the Warmer months, to keep the pond water healthy

Bought this for my new wildlife pond. Really cleared up the sludge that had built up of its first summer. Water is crystal clear and does not smell of stagnation anymore. Highly recommend.

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.

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

I have a small outdoor pond with frogs living in there. The water was dirty and smelly. I tried a few natural things without chemicals but nothing worked until I used this. Now after a couple of weeks I can see the bottom of the pond and the smell has gone.

Was delivered on time and the contents were first class and would order them again when needed

Pond had new pond syndrome (turned green soon after setup) For months I had tried other things and although some helped a little I was begining to think it was never going to clear. Used this and although nothing happened straight away, it has actually worked. Taken just over 3 weeks but pond is now clear. Looking forwards to actuly being able to watch the fish now.

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.

Very happy with this exceptionally easy to use product. Very happy that pond is starting to look better

A little goes a long way. We add it and by the third say the water is crystal clear. We've used it a few time overthe year and it's amazing

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.

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

Doesn't work. Koi eating it all up, my clear pond water suddenly all murky and covered with brown scum.
