In water quality analysis, it is industry standard to report nitrogen compounds in terms of nitrogen content (e.g. NH3-N, NO2-N, NO3-N etc) rather than the concentration of the ion/compound (NH4+/NH3, NO2-, NO3-).  Consequently, our Ammonia, Nitrite and Nitrate test kits follow this industry standard.  While calculations can be performed to convert the reported value to the concentration of the ion, there are some very good reasons why this should be avoided. 

To clarify the distinction between these two methods of reporting, it’s a bit like attempting to count vehicles on a road by counting the number of wheels.  The problem is that, motorbikes will have two wheels, some cars might only have three, whilst lorries may have more than four.  From this example, the number of wheels is largely irrelevant and really we should just count the vehicles instead.  The same is true for the nitrogen compounds – we don’t necessarily need to report the number of other atoms attached to the nitrogen. 

Looking at some of the pioneering and well-respected documentation that discusses the toxicity of nitrogen compounds as they relate to fish health, values for ammonia and nitrite are reported in terms of nitrogen.  As such, the results from our tests are directly comparable with those of toxicity data.  Looking through various websites and contemporary books that also suggest toxicity data,  the numerical values are the same, but there are multiple instances where the units of measurement are not reported.  It should be made clear that these toxicity values we use to ensure our fish are living in a safe environment is actually in terms of nitrogen.  An incorrect assumption that these toxicity values are in terms of the ion concentration combined with the use of a kit that reports in the same fashion will therefore lead one to believing that the concentration of a compound is much higher than it should be.  The consequence? Unnecessary water changes, wasted products in attempting to resolve a problem that doesn’t exist, not to mention the distress caused to the fish keeper!

Of course, if you prefer to work in terms of concentration of ion, you can multiply the results generated by our kits by 1.12 for ammonia, 3.29 for nitrite and 4.43 for nitrate, but be aware of what that result means and how it relates to the target you’re trying to achieve.  It’s very likely that modern literature quotes values without presenting the units properly.  Equally, if using kits where concentration of ion is reported, you should divide the result by one of the figures above for a correct comparison to toxicity data from published sources and our kits.

Koi Water Barn and NT Labs have a long history of working together, we feel that the products in the Koi Care range offer our customers a quality product at a realistic price. This is backed up by extensive research and development that is carried out at the NT Labs HQ located in Kent. They are not far away from our shop at Coolings (Knockholt, near Sevenoaks), this is an added bonus for our customers as they are buying from a local UK based company.

We have been working closely with NT labs for many years now. We stock their Pond range and test kits, we strongly believe they are the best liquid test kits on the market, we use them in-store and have sold many over the years. Last year we have began stocking more of their fantastic ranges including their Pro-f food range and Aquarium range of water treatments.

“I Just wanted to say thank you for the help with bacterial issues I had in my pond. I can happily say that the mouth rot of one fish and the fin rot of two others has cleared up to near perfection now. I have been really impressed with the service from your technical team. I have already recommended online that people ask NT Labs about their products and recommended usage.”

Your Probiotic food is absolutely brilliant! I bought twenty one 1 year old Japanese Koi via a fish farm in Ogata, Japan about 3 years ago. I’ve been feeding them on Probiotic and Probiotic Growth in the summer months. Some of are now 2ft in length and of superior quality. It’s not cheap, but you get what you pay for.

I have used many products for the eradication of aiptasia over the last 15 years. Often with poor results. After purchasing the Anti-Aiptasia, I was astonished with the results! Absolutely fantastic and not like the competitors which normally contains some form of hydroxide. I would highly recommend NT Labs Anti-Aiptasia. This is arguably the best in the market!

I work at a pet store in Durban (South Africa) and have had the best results with my salt water aquariums that I have EVER seen. I have been in the industry for about 10 years now and seriously recommend the products supplied by NT Labs. All our customers that have used anti-aiptasia swear by this product and have said that it over rules every other product out there. Highly recommended.
