Review: Very worthwhile using - Great product have been using them for years, highly recommended, regenerate in hot salt water to keep using until they fall apart.
Review: A bit disappointed - I bought one of these ages ago and now its falling apart i decided to buy another one as the nitrate in my tank was higher than usual. No amonia or nitrite. However even with running this Nitra-Zorb pouch in my canister filter and doing several water changes my Nitrate is still higher than it should be. I was hoping this would cure the problem but sadly not. Maybe its better at removing nitrite than nitrate.

## Questions & Answers

**Q: Would these fit an interpet pf3 filter?**
A: Hmm quite a small filter you could try by folding the pouch? But can’t say for sure. If your struggling with your nitrate levels get yourself some seachem prime very strong stuff these are kinda made for external canister  filters?

**Q: Will this product completely remove nitrates, leaving none for plants in a planted tank?**
A: I found it reduced my level to around 5ppm as the bio filter is constantly processing nitrate it would be hard to eradicate it all for long

**Q: Does this replace the filter pad/cartridge in the filter or can you have both in at the same time?**
A: This works in conjunction with the machanical filtration so you will still need filter pads/sponges etc

**Q: Does anyone have success recharging and using this beyond the recommended two months?**
A: Hello I have used nitrazorb for many years with brilliant results I recharge a size 6 pouch every 2 weeks for 6 months then dis card it never had any issues just place in a container with 4 spoonsful of common salt and very hot water leave until fairly cool then rinse well in cold water happy fishkeeping

### ⭐⭐⭐⭐⭐ Absolutely great massive reduction in nitrates in a week
*by A***R on 26 January 2025*

Absolutely great product. I was doubtful at first as I couldn't find a lot of reviews but within a week my nitrate tests had dropped from dark red (160ppm) to nice pale yellow (0-5ppm). Fish all look a lot happier.
