800 Test Freshwater Aquarium Water Master Test Kit

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 - Nitrate Comes 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.

I keep axolotls, and as any axolotl keeper knows, they are very sensitive to water conditions (although many fishkeepers will know the same about some species of their fish). The point of the API Freshwater Master Liquid Test kit is to enable you to test each parameter safely and quickly to troubleshoot any problems in the aquarium. As a keeper it is also a very good idea to test weekly as part of tank upkeep, after a water change, to ensure an ongoing healthy aquarium. What does it do? Each liquid test kit tests for essential parameters such as ammonia, which is a killer, nitrite, which is less deadly but still lethal, and nitrate, which can cause problems if too high. It also enables you to test for elevated PHs. The kit is vital for testing for 'spikes' in these chemicals. It also enables you to assess the bacteria culture in your tank - if ammonia is converting to nitrate (i.e low or no ammonia, low or no nitrite and under 40ppm nitrate) you have a cycled, healthy tank. What do you get for the money? A computer calibrated test sheet, with colours that show the result of each test - place the completed test sample in its test tube over each colour. Whichever colour is hardest to see through the liquid is the closest match. It also contains a card which tells you which API products to use if you ever encounter problems (although personally I would enquire on hobby boards as they offer good advice). It also contains a booklet detailing how to do each test, with tables at the back to record your own results for a few weeks or so. It comes with four test tubes, which don't shatter when they break despite being made of glass - having four enables you to do ammonia, nitrite, nitrate and PH tests all in one lot). It also comes with reagents to test for AMMONIA, NITRITE, NITRATE, PH AND HIGH RANGE PH. You may need to use more of the nitrate and ammonia tests, as these use two different bottles each to complete each test, and quite a few more drops from each bottle than the other tests. You can buy these separately, but at £18 for a full set, and £6 separately, you may as well buy the full kit. Are the tests difficult? Not at all! PH and High Range Kits require only five drops of liquid with 5ml of tank water (clearly marked with a line so easy to fill) and to be left for barely a few seconds. The most complicated test is Nitrate, as it requires two bottles and over a minute and a half of shaking, but clear instructions are included, step-by-step, in English, French and Spanish. They are not difficult at all and over time can be done from memory. How long do they take? For the PH Tests, a few seconds. Each of the others requires five minutes to develop. The Nitrate takes as long as 6 and a half minutes because of the shaking process. Any tips? When testing, always leave bottles on a flat surface to avoid them rolling off. Also, with the Nitrate test, add Bottle No 1 to the test sample, shake to mix, then place on a flat surface. Remove the plastic lid and wipe it out before replacing - I find this prevents a lot of leaking when you do Bottle No 2's test. Do you recommend them? Definetely! I knew very little about tanks but the kit enables me to keep on top of their upkeep easily and is invaluable for ensuring my axolotls aren't sick because of parameters. They are easy to use and last ages - my last kit was bought in April (6 months ago) and I am only ordering a new one because I broke two test tubes and am running out of the Nitrate tests. They are much more reliable than the strip tests - the API kit is also the most recommended kit on Caudata.org, one of the best amphibian sites on the net, and also one of the cheapest. The only downsides are that the nitrate runs out quicker than the others, and that I have managed to break two test tubes by moderate falls, but buying a new kit remedies that, and as I said before, the glass does not shatter - the bottom simply falls off it it meets a hard impact. The colour charts can be difficult to read, particularly Nitrate, which has around three shades of orange or red that can be hard to distinguish - ask for a second opinion and always do them in good light to remedy this (if desperate ask on a forum, posting pictures), but generally Nitrate is the only one you may struggle with. Overall, one of the best purchases possible for your aquarium.

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!

Not going to a write a lengthy review. I just have to say this test is worth it. Easy to use. Instruction manual is clear.

Great kit to have. Instructions are simple and easy to understand. Good value for money. Enables you to monitor the levels in your tank easily enough. Would recommend to anyone with an aquarium!

I’ve been using this test kit for a few weeks now and it has completely transformed how I manage my aquarium. The instructions are clear and straightforward, even for someone without much experience. Each test is simple to carry out and gives quick, reliable results. It covers all the essentials—ammonia, nitrite, nitrate, and pH—so I feel confident that I’m keeping the water conditions safe for my fish. The colour chart is easy to read, and the kit comes with enough supplies to last quite a while, which is great value. Since using it, I’ve been able to monitor and adjust my water parameters more effectively, and I’ve noticed my fish looking healthier and more active. A brilliant product that I’d recommend to anyone serious about maintaining a healthy aquarium.

I’ve never tested my fish tank water properly in the past but after watching some you tube videos decided I should take more care of my fish. This kit is very easy to use and gives you the test results within minutes and either gives you peace of mind or lets you know what needs adjusting to balance your tank. It is pricey but this was the cheapest I found including delivery.
