Review: Great but might not be safe for frogs - 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.
Review: Works well - I use this when re-scaping planted tank - it really helps to clear up the murky water caused by disturbing substrate.

## Questions & Answers

**Q: Hi, I have a 15l tank, what would the dosage be in litres please? Thankyou 🙏**
A: 1ml

**Q: Does this remove the brown in the water from wood tannins?**
A: I don't think so no. It makes fine particles clump together making them easier to be filtered out hence clearing the water. Wood tannins is a colouration so will have to be gradually reduced with water changes. Tannins are not harmful though.

**Q: Can this be used with or instead of aqua pure balls?**
A: it can be used with pure balls accu-clear is a water polisher and can be used in all freshwater tanks

**Q: Dosage plz for a 21.6 litre tank**
A: Half a cap every 2 weeks

### ⭐⭐⭐⭐ Crystal Clear
*by P***R on 23 May 2013*

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!!
