API Nitra-Zorb Pouch, Size 6

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.

I needed to set up my Betta aquarium quickly, and with no time to let the nitrogen cycle complete, I ended up with elevated levels of ammonia, nitrite, and nitrate. After using the API Nitra-Zorb pouch, everything returned to normal, and my water parameters are now perfect! It’s been a lifesaver for my Betta’s health, and I couldn’t be happier with the results. Highly recommend this for anyone who needs to quickly stabilize their aquarium water.

easy to use, but not sure how effective the pads are

It works. Nitrite and nitrate levels were 10 and 80 before i placed this in the tank. Was very anxious about the health if my fish. Within a day of placing the pouch in the tank, they dropped to 3 and 20. Phew. If it was not for This product i was very worried about the survival of the fish. After a thorough wash in clean water I just placed it at the bottom Of the tank. It was too bog to be placed in the internal filter. And the levels Dropped. Today i have attached it by rubber band to one side of the filter. I believe the levels of nitrate nitrite will drop to zero. Ammonia was always zero anyway. Great product highly recommended

Seems to reduce the nitrate a little but not by as much claimed

Everyone who keeps fish has to deal with the problem of nitrates building up in the water. Even using a nitrate filter to remove nitrates from your tap water does not solve the problem. Water changes (the usual solution) are time consuming and if you have a pond, water changes in the Winter are uncomfortably cold. Nitra Zorb is an absolute boon, not only do the sachets remove nitrates you can "recharge" them for re- use using aquarium salts. A great product.

Guys can I put this directly in my tank? It has brought the nitrates down a wee bit but nit ad much as I would have liked. The reviews are amazing but I'm using a jewel bioflow 3m0 filter and tbh I think I have it in the wrong place within the filter. Can I stick it near the internal filter but outside it?

My aquarium is a worst case scenario for these pouches.450 litre heavily stocked with large fish.25% water change every week.Before pouches. 0 Nitrite, 0 Ammonia, 80ppm+ Nitrates.Added two pouches for two weeks with no discernible change in Nitrates. The water did go clearer so the pouches were removing tannins and green tint from water.Added four pouches and nitrates started to come down.Four pouches after 8 weeks and nitrates are around 40ppm.To get nitrates lower would require yet more pouches which makes it economically unviable.This product works but not as good as Nitra Guard cubes which bring nitrates to zero after two weeks. Problem is Nitra Guard is becoming increasingly more difficult to get hold of in the UK.In conclusion these pouches work but will not have dramatic effects on heavily stocked aquaria.(update 01/07/2024)Using these pouches for a while now and regenerating every 7 days. Nitrates down to 40ppm.
