API ACCU-CLEAR Freshwater Aquarium Water Clarifier 8-Ounce Bottle

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

Works well

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.

After syphoning up the "gunk" off the bottom of the tank and scrubbing the algae off the glass the remaining water can be a bit like soup and probably not pleasant for the fishy residents. I don't like to think the suspended junk will just settle again so tried this (as directed on the label). Turns the water an amber colour but within an hour or so the water was crystal clear and after a further hour the coloration had faded. Depending on how long the mechanical filter has been in your filter kit you may need to remove and change it (or rinse it) as I found the flow rate of my Fluval G6 dropped - on removing the mechanical filter there was more gunk in it than I've seen before so the Accu-Clear certainly did what it says on the tin!!

Works really well

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.

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

I used to use Tetra Crystal Water, but thought I'd try this API stuff, First time I bought it (not from amazon), it did what it said, lovely clear water. But this last purchase from here and as soon as it touches my Aquarium water it turns very cloudy and slowly clears up over 3-4 days?????, It never did this with the last batch I bought nor the Tetra stuff. Fish are fine and water test is spot on so............ god knows why this bottle is doing it. I should add that it does this in both my tanks. I also measured it out for both tanks (120ltr & 60ltr)

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!

Wow!! Super impressed!!! Water is amazingly clear!!!! I thought this would be a scam but it actually works and works well!!! It did not kill any of my fish either. Highly recommend!
