I’ve been using this with my cycle to jump start my liverock into growing bacteria that converts nitrate to nitrogen gas. I believe that’s how this product works. I can say I’ve seen huge drops in nitrate after 3 weeks of starting. Usually your nitrates will skyrocket towards the end of a cycle, this has got them from over 100ppm down to 40ppm with no water changes. And I’m still dosing ammonia. Pretty great stuff. Hoping I don’t have to keep dosing nitrate reducer once the bacteria population is big enough. But im sure I’ll figure that out over time.

I used this on my 36 gal. bow front freshwater rainbow fish aquarium, my grandson’s 20 gal. molly, swordtail freshwater aquarium and at work on desktop 7.5 gal. low pH, soft water tetra aquarium. My personal tip to new user is when you put it, turn off all your filters, powerheads and etc. for 15 – 20 minutes and let it all slowly sink to the substrate. Air bubbles seems ok to leave on. Then after that time turn the filters back on. That has worked best for me, no dissolving problems, no dead, fish, no nitrate. If you don’t the stuff floats around the fish tend to pick at it until they decide if it is to eat or not so I choose not to confuse and let it sink. I think it is a safe beneficial product and I have had only positive results. My 36 gal. bow use to jump from 15 PPM to 80 PPM in a week because of the decaying driftwood I’m sure plus food and etc. I do not use live plants, personal choice age related. Started using this, results are the creep is now manageable. I have used Nitra-Zorb which worked great but it requires refreshing with hot salt water for two hours then back in. Lot of trouble and then one day I had a pouch that the seam split and let product in with my fish while at work. I lost 3 rainbows. May be good but I’ll never use that again. This product is easy to apply, easy to store, safe for the fish and I like it. Now I will say they could do better on the long term use instructions but the cap being well marked for measuring either 5ml or 10 ml is perfect compliment to the ease of use.

I have a 40 gallon tank with a 15 gallon sump and my nitrite levels were givin me a fit. it was taking forever to cycle and balance everything with 2 clowns and a damsel fish. i finally purchased this nitrite reducer and my nitrites went from over 10 ppm to 0.0 ppm in 4 weeks after only 2 doses. Good product! Does what it says.

I read all of the reviews about this product and still thought I would give it a shot. After just one bottle the nitrate levels were already lowering a bit. After the second bottle, the levels were nearing 0. So now I’m on my third bottle and hoping to get the levels even lower. If not that, then at least it will really help maintain the tank at a great level.
