API Saltwater Master Test Kit for Saltwater Aquariums (550 Tests)

I purchased this for my recently set up Axolotl tank. The instructions are very clear and easy to follow! Gives accurate results and you get so many tests out of this kit :) Highly recommend.

The only freshwater master kit i will use. Test strips i never used due to there poor accuracy. There are some other brands like Seachem for example that do great water testing products but much more expensive to. If you want good accuracy for a reasonable price that will last a reasonably long time then overall value and quality is definitely given to the API Freshwater Master Kit.You can perform the following tests with this kit:- pH - low range- pH - high range- Ammonia- Nitrite- NitrateComes with easy to follow instructions and colour chart. The most annoying are the test tubes, i always end up breaking them and having to buy spares, i also hate they are push caps and not screw on as you have to keep your thumb on top of the cap when shaking as it tends to leak out otherwise, i also wish the case layout was better as well as it's a bit annoying and fiddly specially the position of the test tubes. I also purchased the API liquid Kh and Gh kit to make it a true master test kit. I think they should be included as standard as this is called a master test kit after all.Make sure you shake the plastic liquid bottles very well before using, i shake longer than the instructions state to ensure it's mixed well, specially the nitrate bottle as it's very thick formula and prone to giving inaccurate readings simply because the bottle was not shaked enough before using, so take note shake and shake again.I recommend this kit for any fish keeper whether you are newbie or advanced user, this kit is suitable for most peoples needs. I tend to only test frequently when cycling a tank and for approx 6 months after cycling complete whilst beneficial bacteria still colonizes in the filter, i don't test often from then on as i find observing the tank and fish can give you good indicators of problems, but nonetheless still a great kit to have to hand for as and when needed.Check readings in natural daylight if possible as can sometimes be hard to judge colour of tested water against colour chart.Best kit for overall price accuracy and price. Highly recommend.Tips:- Check expiry date is well in to the future on case when it arrives as they last ages.- I find placing the colour chart up against a window with natural daylight (but not direct sunlight) and then placing the tube by the side of the test i'm testing enables me personally to take a better reading.- Another way some people find easier is to place the colour chart down flat on a surface in a room with natural daylight, then remove cap from test tube and then place the testing tube on top of the colour chart and test they are testing for, then look straight down the test tube and compare colour.- Some people complain of the colour in the test tube changing over time and not sure which reading was correct, this will happen hence why it's important to follow instructions. If for example you are told to compare the test tube with colour chart after 5 minutes, then ensure you compare after 5 minutes and not for example 10 minutes, as overtime the colour will continue to change and people then get confused which is the correct reading.- Shake the Nitrate bottles as it's very thick formula and prone to giving people false readings, read the instructions very carefully, a number of people do the Nitrate test wrong and get inconsistent inaccurate readings. You must shake this bottle excessively. I always shake the bottles longer than the instructions state to ensure they've been shaken enough, if you don't shake them enough you can end up with inaccurate false readings.

This fish water testing kit is a must-have for any aquarium enthusiast! It’s incredibly easy to use, and the results are both accurate and reliable. The instructions were straightforward, and I was able to test my water in just a few minutes. The kit includes everything you need to check all the essential parameters—pH, ammonia, nitrite, and nitrate levels—and the color-coded chart made reading the results super simple.I love how this testing product gives me peace of mind, knowing my fish are living in a safe and healthy environment. It has really helped me maintain the perfect balance in my tank, and I’ve noticed a huge improvement in the health and activity of my fish since using it regularly.The value for the price is fantastic too—there’s enough material in the kit to last for multiple tests, so I feel like I’m getting a lot of use out of it. I would highly recommend this testing kit to anyone who wants to ensure their aquarium stays clean and healthy. It’s a reliable, affordable solution for keeping my fish happy!

This product is fantastic, slightly expensive but incredibly accurate, far better than test strips (which are still good to have just to check the water quickly). This test does take a good 10 minutes in total (you'll see why below) but it's worth it for the clear results you get. The only annoying thing is there are 4 test tubes with it for 5 tests (P.H, High P.H, ammonia, nitrite and nitrate) hence the 4 stars instead of 5. My tip is to ask a pharmacist for a 5 or 10 ml syringe to keep in the kit to draw out the water from the tank, saves messing about.Will definitely buy again when this kit runs out (not entirely sure how long it will last) ammonia showed 1ppm on my 1st test (should be 0plm) which made me do a slightly higher water change than planned, now little buster (my betta fish) seems much happier! I have put the instructions below after watching a really helpful video online:Instructions:Fill each test tube with 5ml of water from the aquarium, be sure when adding solutions to hold bottles upside down (not angled) to ensure uniform drops. Ammonia and nitrate solutions have 2 bottles per test, make sure to read which bottle to use first.PH- shake bottle a few times, add 3 drops to test tube, add cap to tube and shake gently a few times. Results are instant.High PH- shake bottle a few times, add 5 drops, add cap to test tube and shake gently a few times. Results are instant.Ammonia- Bottle 1: shake gently a few times, add 8 drops to test tube. Bottle 2: shake gently a few times, add 8 drops to same test tube. Add cap to tube and shake VIGOROUSLY for 5 seconds. Results ready in 5 MINUTES.Nitrite: shake bottle gently a few times, add 5 drops, add cap to tube and shake gently a few times.Nitrate (read carefully) bottle 1: shake gently a few times, add 10 drops to test tube. Bottle 2: shake VIGOROUSLY for 30 seconds, add 10 drops to same test tube, add cap to tube and shake VIGOROUSLY for ONE MINUTE. Results ready in 5 MINUTES.Hope this review has helped, happy fishkeeping!

A really useful kit for anyone keeping a freshwater aquarium. Being able to check water parameters is an important part of looking after fish, and I like having everything together in one kit. A handy addition to my aquarium supplies and something I would recommend to other fishkeepers.

API Master Test Kits are an essential bit of kit for all aquarium keepers. This product should be at the top of your priority list when setting up a new aquarium, and will remain an essential piece of kit throughout your hobby.I purchased the Freshwater version as I keep tropical fish, but they also offer a Saltwater version for Marine setups.The kit tests for PH, High PH, Ammonia, Nitrite and Nitrate, and will greatly assist you in ensuring your water parameters are at the correct levels for keeping fish. Not only is this essential for setting up a new aquarium (helping you to determine how far through the initial cycle you are), but it's also essential for ensuring your water parameters are stable in an already cycled and mature aquarium setup.Test solutions for each parameter are provided, along with 4 test tubes, instructions, and a colour match chart. All of these are neatly stored in a plastic container, as shown in the product image.In a nutshell, you add 5ml of aquarium water to a test tube, add the required number of drops of solution per test, and then shake each test tube. Leave the test tubes to stand for 5 minutes, and then compare the colour of each against a colour match chart. The procedure does vary slightly from test to test, so please follow the instructions carefully.The product states that you will get over 800 tests out of the kit - 800 being a combination of all 5 tests. However, what you're likely to find is that you run out of certain tests before others. The Nitrate test, for example, takes 10 drops of solution from 2 bottles (20 drops in total), whereas the PH test takes just 3 drops from one bottle. It doesn't take Einstein to work out that you will use up the Nitrate solution before the PH solution. Fortunately though, you can purchase individual test solution bottles separately, but at a premium over purchasing all of the test solutions together in the Master Test Kit.The only downsides to this product are:- 4 test tubes are provided - It would have been nice to have 5, as there are 5 different tests included within the kit.- The colours can be a little hard to read, especially for those of us who are colour blind.Overall an excellent product, and highly recommended. Even with the above minor flaws, this product still deserves a 5 star rating.Forget the cheap test strips, and buy a liquid Master Test Kit!

Working great for my testing needs

I was recommended this kit by a Knowledgeable fish man in one of my local fish/pet shops. Even over buying what they had in their store (strips). It’s brilliant. Also fees like doing potions. I thought it would be difficult to do but it’s so easy. My fish tank is thriving

Value for money.
