API ACCU-CLEAR Freshwater Aquarium Water Clarifier 37 ml Bottle

It works very well. I have used it twice on my tank as directed on the bottle. Both times gave a similar result. Takes about 12 hours to work. I did have a baby frog in my tank which died 2 days after I used this. I'm not sure if it was due to adding this as the frog was new to the tank and everything else has been totally fine, so maybe don't use it if you have a frog just in case.

amazing stuff,makes a cloudy tank water crystal clear in a matter of hours

Works well

New tank was very very cloudy 2 months later even though water tests were showing the water was all in parameters - mine personally took about a week to show any difference, I just trusted the process. Superb and made up with the results - just make sure you follow instructions and be patient x

This stuff is amazing and its not overly expensive either. I set up a new tank with plant substrate, sand and gravel and as a result, the water was extremely murky and cloudy with sediment. I used filter floss and Accu-clear ad within 3 hours my tank water was crystal clear. As I haven't got any fish in my tank yet I can't comment on how it affects them but hopefully it'll be ok and I'll be able to comment on that later.

I use this when re-scaping planted tank - it really helps to clear up the murky water caused by disturbing substrate.

Does what it says

before using this my fish tank was so cloudy it looked like someone had poured a carton of milk into my tank you could not see anything so i bought this and i put half a cap full into my tank a couple hours ago and already my water is crystal clear! i have never ever seen my fish tank water so clear it’s amazing stuff definitely worth the money. i wasn’t so keen on putting chemicals in my fish tank but my fish are still healthy and fine so i can say it’s safe to use and wk t kill your fish 10/10

Great!

Avant sur un aquarium de 800l, les espaces de nettoyages étaient de 15 jours voir 3 semaines maxi, depuis que j'ai découvert cet article, mes nettoyages sont aujourd'hui espacés d'un mois et l'eau est toujours limpide pendant toute cette période. Aucun problème sur les poissons et les plantes

SuperFast Delivery, Quality Product

The first 2 days after putting it in our 35 hex, it was cloudy as heck. But then we woke up to the clearest tank ever. I changed the filter, which was new when we put in the clarifier, and it was filthy! I guess it did a great job!

Ottimo prodotto, l'ho utilizzato in un nano acquario e dopo 24 ore, l'acqua è diventata cristallina, peccato soltanto che trovare prodotti dell'API in Italia sia molto difficoltoso.
