Eliminates Nuisance Algae & Improves Water Quality in Ponds Naturally – Best Algaecide Alternative (500ml)

It didn’t work for me, maybe I didn’t use it correctly

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

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 !

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.

Been using a few weeks and pond stiil as green

Added to pond with string weed and cleared pond in couple of weeks.

Great product,tried many products over ten years.This is the best,ive used.

Does not work

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.

I didn’t realise product was for outdoor pond use.

As the title suggests. Used proper dosages until bottle was empty. Still have algae in pond ..

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
