## Questions & Answers

**Q: does the dye filter out**
A: We only have an ultraviolet light filter, just in case, but it stays black. Because it's black it doesn't need cleaning yet. It's been in 2months.

**Q: Can I use this to dye mulch as in wood chips for garden?**
A: Yes

**Q: would this hide the pump in a small water feature?**
A: this stuff is great and very dense in colour (wear gloves). it turns the water jet black. anything submerged will not be seen. add it gradually until you reach the desired depth of colour - a little goes a long way. it also helps to keep the algea at bay. hope that helps

**Q: Would this dye stain a white bathtub?**
A: don't know ive only used it in glass

## Customer Reviews

### ⭐⭐⭐⭐⭐ It works!
*by J***C on 16 March 2025*

I used 2 small bottles last year in my largish pond. put it in as soon as it started to really warm up, and went the whole season without suffering from the usual plague of blanket weed. the man who looks after my pond's filtration system suggested it. It works! you can still see the fish, and everything looked great. Have purchased the large size this year because its more cost effective.

### ⭐⭐⭐⭐⭐ Stunning Results
*by J***Y on 19 July 2024*

The media could not be loaded. Crystal clear water is always good to have in the garden pond but the downside is that the fish were easily seen and picked off by the heron.I opted for the black dye as this suggested a mirror finish and dark looking water. In addition, it can also reduce algae buildup as the light does not penetrate as much. Clear instructions are included based on how much water your pond holds.The results are superb. I highly recommend this product and the results are better than I had hoped for. A massive 5 star rating

### ⭐⭐⭐⭐ the pond looks like a mirror- perfect
*by S***E on 26 July 2023*

Didn’t need to use much & seems to be lasting very well
