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.

The product is excellent and you will see results in a few daysThe bag it comes in is large, too bulky and disintegrates quickly so before use transfer contents to a muslin bag this will make it easier to use and gives options for smaller filtersEssential you follow re-charging instructions this will give the product a much longer life than the manf. states

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.

I have a Juwel Rio 240L tank. I have had a really high nitrate reading for a while now. I tried almost everything recommended to lower it with no success. Then one day whilst looking for something to lower the nitrate level this product appeared on the page I was looking at. Not cheap but thought ' oh what , I'll give it a go '. So pleased I did. Within 5 days the level had dropped from 50/60mg/l to under 20mg/l. So I am so pleased. I took it out on day five and recharged it in aquarium salt as it says. The water went a really dark brown, can only think it was the nitrate coming out. I placed it in the bottom part of the filter on top of the ceramic chips basket. It's a bit of a squeeze but seems to be doing the trick. I have two filters going in the tank and seem to be working as usual except the nitrate is way down. Just one thing, I've still got an original Juwel nitrate sponge going. Wasn't sure what to do about this so thought it can't do any harm. So fingers crossed it's going to keep doing its job!! Thoroughly recommend.

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