FluvalClarify Bio for Aquarium Water Treatment, 4-Ounce

Ordered this when I was out of the Quick Clear with the baby blue wrap at the top, and this works MUCH better at keeping our turtle aquarium crystal clear. 2 capfulls about once a week, and topping off the water as needed, is all it takes. We have an FX pump/filter, which obviously helps, but this keeps the tank clearer longer than the other stuff.

This stuff works great! I had super cloudy water due to it being a newly set up tank and this cleared it up and made it crystal clear water! I used it a couple times to clear the water up and hadn't used it any more.

The media could not be loaded. Only thing I use for many years sometimes it’s hard to find but it’s great

Boy, I thought I was having trouble with my filter. My tank (with only one large goldfish and a Pleco) was milky cloudy and stunk. I spent more than a few months trying to troubleshoot the filter (Fluval 605 canister filter, I think.) I bought this after reading about it online, and shoot! This totally solved my problem! My water is crystal clear again, and it smells like a healthy fish tank again. This is definitely worth trying if you have cloudy water.

I must say this a great product and I'm a person who share honest reviews so I can direct others..will do the trick n I'm pleased

I recently got a new 10 gal aquarium and the tank kept getting cloudy. The first time I ended up changing all the water, the second time I started searching the internet for the cause. When I learned it could be a bacteria bloom, which happens often to new tanks and tanks where fish have been over fed, I started searching products on amazon. Fluval was a cheap solution and was highly recommended by users. It works on the first try, but afterward it seems to loose it's effectiveness. I think it only works when you order it fresh. But after you open it for the first time and use it the remaining product does not work anymore.Shake it well and make sure you do not pour too much chemical into your fish tank. If done right, you should notice results within hours. After 48 hours my fish tank is crystal clear again. The fish were not effected in any way.Overall you are better off getting something else.

Killed nearly all of my fish!! Don’t buy! No issues with accu-clear by API.

So I had some a complete clean out of my tank and filters (water was crystal clear) and for a couple days after, the water was fine and then the cloudy mess happened. I ended up using "Acurel F" which is an organicly based quick fix product that once you start using it, you have use it EVERY day. And it's not cheep either. But what happened was my filters started growing this weird alge and the particles that that stuff would clump together started to gather like crazy all over everything. It was disgusting! Don't recommend that product at all even though for a few hours you get pretty water. It's also mildly acidic, and I used too much and some of my fish died :-( so I found this great stuff and it has been working like a charm. Slow process, but it did have A LOT of organic matter to start clearing out of my tank. Very happy so far and I'm on day 4 after the 2nd treatment on the evening of day 3. It doing its job for sure, and I feel so relieved. I will FINALLY have a pretty tank again. Highly suggested by me to you if need help with the water clarity. I'll post back again to give another update in a couple daysOk day 5 and my tank is crystal clear- absolutely stunning. Very happy and definitely recommend
