## Description

Fluval Clarify Bio for Aquarium Water Treatment, 4-Ounce

Review: Be patient - it works great! - 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 days Ok day 5 and my tank is crystal clear- absolutely stunning. Very happy and definitely recommend
Review: GREAT! - 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.

### ⭐⭐⭐⭐⭐ Really worked, I was surprised how well
*by C***L on May 17, 2020*

1st day, I put product in tank with Fluval Biological Cleaner for Aquariums also. Don't know if that made a difference but it didn't hurt. 2nd day kinda noticed a slight change in water. 3rd day it looked pretty good. I figured this was end result. Nope 4th day looked even better. This is the 5th since I put in the product and my tank is crystal clear. I'm amazed, I'm really amazed that this product worked so well. I'm sold on this , I've tried SO MANY and wow. Makes me want to get more aquarium's, lol. I have two 36 gallon tanks right now. One planted that has algae problem so bad...will try product one it next. Will up date and see what happens. UV light works on it but not much else.
