Unreal. This is the future of instant cycling for sure.

So. I've not had a tank running for years and years now and recently decided to jump back in.

I was doing the oh so ghastly, shock horror 'fish in' cycle. I've been doing daily water changes and dosing Prime & Stability. I got to the point of daily readings roughly .25ppm Nitrites which would be cured with a big W/C but always came back the next day at .25ppm.

Until I added nitrico goop. I left the Nitrites high, about .50ppm added the Goop and pre seeded Nitrico media and dosed some Prime and Stability. Came home from work the next day and tested expecting to see high Nitrites and needing a big water change. Nope. 0ppm nitrites. 0ppm ammonia. 5ppm nitrates.

An almost instant cycle in 24 hours.

I'll be keeping a close eye and still testing
daily, but it looks like I'm essentially up and running now thanks to Nitrico.

Say goodbye to 4 week tank cycling, the future is here!

After reading reviews I ordered 2 x 250l pouches of the fantastic Nitrico Goop for a new tank containing 25 African mbuna cichlids. I was able to pick a specific delivery date and before purchase I emailed Jack a million times who was really helpful answering every question I had in detail. It's now been a week and the tank is happy and healthy with no water quality issues, every day I've done tests and the water is bang on perfect every time not to mention it's crystal clear.

What an innovative product, whoever thought of this should win a Nobel prize! Fantastic service, I'll certainly be using again 👌

Ordered the nitrico goop a week ago

Ordered the nitrico goop a week ago . I had 2PPM of ammonia in my tank I used the dr times to dose it up to that level. It’s now been a week and it still hasn’t gone to 0PPM it’s just stuck at 0.50 which I can’t understand. The product claims in instantly cycles your tank which may be the case but on my experience it has not done that. Considering I payed £25 for a pouch that hasn’t worked in my opinion. I probably won’t be using this product again.

Magical Goop.

Easy to order. Goop was delivered exactly on time. Easy to follow instructions. At the start, the ammonia was close to 4ppm. My 40lt tank was fully cycled in approx 60 hours from when I put the Goop in with no lost fish. Nearly a week later, the water parameters are still where they should be, and we have happy fish swimming around. Thank you for the magic Goop. It saved our Betta and my Platy ladies...

Fantastic company

Fantastic company, knowledge and customer service. I have used Nitrico several times over the years for both mature filters and goop, and they're products are amazing. When I needed advice I rang them and they were very helpful. Any issues - they are super pro active at being in touch on email or on the phone. Outstanding

10/10 ⭐⭐⭐⭐⭐

First of all, I'm not the most experienced when it comes to setting up a fish tank but since speaking to Nitrico i have gathered a much bigger understanding of it all. Nitrico are so helpful, always have the time of day for their customers and explain everything you need to know. Not only that, the product (Nitrico goop) is 10/10. Highly recommend this product and company to anyone! ⭐⭐⭐⭐⭐

Fantastic!!

I'm absolutely blown away by this product and company.

I was experiencing an ammonia and nitrite spike in my tank due to adding additional fish and then having to replace my broken filter. These two issues combined caused a spike in Ammonia and Nitrite, which I noticed early on thankfully.

I tried adding various filter additives like Seachem Stability and API Quick Start which helped a little but I was still having to do water changes daily to prevent fish loss.

I then discovered Nitrico, after doing a little reading I placed and order of a 250L and a 75L bacteria pack. I placed the order around 12:30pm and the beneficial bacteria arrived the next day!

The day it arrived I decided to do another water change as the nitrite was still way too high. I then added the bacteria directly to my Fluval FX6 filter as directed by the supplied information sheet. The consistency and appearance of the pouch wasn't pretty and I was hesitant to add it to my filter, but I took a chance and did it anyway as at this point I was 2 weeks in to daily water changes. I mixed the bacteria pouch in with the filter media and let it sit for 15 minutes before connecting it back to the tank. I then started the filter up and the tank instantly went really murky but after 20 minutes this had cleared completely.

I left the tank for around 6 hours before performing another water test and I was absolutely amazed by the results. Everything was completely normal! 0 Ammonia and 0 Nitrite in the tank and the Nitrate has risen slightly as to be expected during the cycle. I added half of the 75L pouch in to the tank at the filter intake the next day as a top up and the remainder in to my smaller tanks filter.

I haven't had any issues at all with water quality since adding this so it will 100% be my go to bacteria additive when adding new fish or stocking a new tank.

100% happy with the product and the company.
