Expensive and didn’t work
Expensive. Application dosage is measured in drops but it is not a dropper bottle. Did not make any difference whatsoever. Now trying barley straw.

it works
I have used other products in the past but nothing really worked that well. This one worked after just one application ( had to wait about 1 week to see results). Had to apply again within 3 weeks but the pond looks much better.It is small bottle for the price but for my 4000 liters pond I need just few drops !

Nualgi works to clear algae from pond
May seem a bit pricey, but just one tiny drop of Nualgi each week has gradually and safely cleared our fish pond of green algae so we can readily see our fish and enjoy our pond. Took a while to take effect tbh, but persevere and you will get results. Worth the money for so little effort. Recommend.

Pond looks great
I have a biological filter but still had some algae problems. This products seems to be very good at finishing off the troublesome stuff.I note some of the comments expressing disappointent. No one algae treatment will be a magic bullet. You need cool water, oxygen etc. I find just speeding up the waterfall had a huge beneficial effect in getting rid of algae and it did it almost overnight. An additional founain or moving water feature might be helpful for some people. Lots plants increase oxygen and reduce heat. . I have tons of fish - but the fish load increases algae so think about reducing fish if algae is still problem. Other than that these types of products - and I use other pond bacteria as well - certainly help but you have to do th rest.

Makes a difference but not perfect
Big issue with hair Algie in my pond. This product helps but by no means does it irradicate it completely. Not the magic bullet I was hoping for unfortunately
