Marine Multi-Test comprises everything you need to carry out 155 tests (combined) of the 4 key water parameters to keeping a healthy marine aquarium: ammonia, nitrite, nitrate & pH. All tests use liquid reagents for improved accuracy. Full instructions are included detailing optimum levels and suggestions for correction, along with an integrated test tube rack. Simply follow the easy-to-read pictorial instructions and compare the test tube to the colour chart. Complete with 4 test tubes and a set of colour coded stickers to allow you to label both the test tubes and lids to ensure the same test is always carried out in the same test tube to avoid contamination.
This test kit reports concentration in terms of nitrogen (NH3-N), (NO2-N) or (NO3-N) to be compatible with reported safe concentrations as they apply to fish and plants. If you are interested in knowing the ionic concentration of the measured parameter, multiply your result by 1.21 (NH3-N), 3.29 (NO2-N), or 4.43 (NO3-N).

Q: Why do I run out of 1 reagent before the other(s)? A: We fill our test kit reagent bottles to a minimum amount before they are put through a vigorous QC regime. This means that the vast majority of bottles will in fact be overfilled by varying amounts meaning that the reagents may well run out at different rates but you should be able to carry out at least the number of tests stated on the packaging.

"The customer-friendly winning product had eye-catching packaging, which
provided the consumer with some very important information about water testing.
Any product that encourages fishkeepers to test the water in the their own tanks more
often is a welcome addition to the market." Judges, Aqua 2019

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.

Excellent technical department that knows it's chemicals as well as it's fish!
At FishCove Aquatics we are huge fans of NT labs range of products we have seen fantastic results using the food and even bigger results with the liquid fertiliser. Tried and tested by us recommend by many.

“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.
Paul Munday - Consumer review
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!
Viv Samuels-Lee - Consumer Review
We use Blanketweed Balance, and find it highly successful in the battle against Blanketweed.
We recommend it to all of our customers and feedback is very positive.
It is now our best selling Blanketweed treatment.
Another top quality product from NT Labs
Roydon Hamlet Water Garden
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.
