Presenting the most affordable product on our list- API calcium testing kit. Now, just because the product comes at a lower price, many people could question its accuracy. 

Fear not! API products have been known for their affordable prices all the time. And, all of them have lived up to the brand’s reputation for being products with excellent quality. 

So, let’s talk a bit about this particular product- 

One thing everyone underestimates about testing kits is the experiment process. While we do believe this product is easy to use, it has some drawbacks. But, let’s begin with the process, first off- 

The vial should be filled up with the water of the aquarium. Then, proceed with the solution bottle as you’ll shake it up. Next, drop it to the vial again and observe the colors changing to blue. 

Even though it works well in the case of this product, you’ll have to put in an additional step. Here, you’ll need to shake the vial every time after dropping in each drop. As a result, it’ll eat up some time. 

As if that’s not enough, some drops leak out of the vial. Even though there’s a plastic cap, it’s still not enough to stop the small drops. And, that can be an absolute pain! 

Moving on, this product comes with an accuracy of 20 mg/L. Well, this isn’t bad, to begin with. But, it does lack behind the previous product. 

When it comes to reliability and precision, this kit held up pretty well too. We’ve tested this kit ourselves for quite some time against other competition too. And, all of the time, the kit provided consistent results. 

So, it’s safe to say that this kit is reliable even though it comes at a lower price. That’s why if you’re looking to save up some cash then give this product a look. 

With a lower price and great features, this product brings a lot to the table. And, it offers a great deal.

  • Comes at a lower price
  • Easy to read
  • Pretty straightforward usage
  • It’s reliable and precise

  • Leaks a bit from the testing vials

Product Overview

Now, why have we put this one at the last? And, how is it so much different from the first product? Well, the obvious difference is that this product isn’t electronic. 

So, you’ll have to go through a more traditional way of measuring things. And, the process of testing won’t be that easy when compared to the first product. But, that said, both the products follow the same accuracy of ± 6%. 

Thus, there’s a bit of win in both situations, right? Well, there’s a lot to discuss. So, let’s begin- 

As we’ve mentioned, it’s not going to be as easy to test this product out as the first product. This means you’ll need to wait it out for a bit. Other than that, the results seemed accurate and reliable all the time. 

But, the only drawback we felt was the process of experimenting. Because it took us some time to calculate the results. As a result that, you might have a hard time figuring out the methods of doing it. 

Even though we believe the results are accurate and reliable, the experimenting process makes us deduct some points. But, we do believe this won’t be a dealbreaker of any sort. 

In fact, many experienced reefers have praised this product as they know how to calculate the levels. So, if you’re not new to this, things won’t be confusing at all. 

So, we’ve shown the differences between this product and the first one. Now, the choice is yours. Even though this one costs less than the first product, only you can decide what’s needed. 

Pros

  • Provides accurate results

Reading Time

Reading time matters! After all, you don’t want to leave everything in the air and wait for your calcium levels. Even though most traditional testing kits take less time to show results, there could be some annoying ones. 

And, if you feel like reading time is very important for you then we’d suggest moving to an electronic one. Here, you’ll get an instant result right away. So, you won’t have to wait for a bit. 

Testing Process

Testing the calcium could be a hard task on its own. Here, you might need to worry about titration. Also, you’ll need to check whether the water is spilling or not. 

Here, the easier the testing, the better it’ll be for you. Hence, settle down for the products that don’t need additional steps in the testing. 

Just shake the vials, put them on the solution bottle and see the colors changing up. That’s all needed, in the end. 

Readability

Yes, this is quite the issue. If the color changing isn’t noticeable. Then, it would be a large problem! Readability is crucial as you’ll judge the calcium level from it. 

Hence, it’s better if you have a product that shows the readability large and clear. Here, the electronic testing kit does a great job as it shows the results in a large LCD screen without any complications. 

Budget

Well, nothing matters if you don’t have the right budget. If you have some extra money to invest, the electronic testing kit could be a great option. And, if you want to save up on some cash then settle for something low. 

While many believe the cheaper testing kits provide inaccurate results, we believe it’s a misconception. So, set your budget and then make the purchase. 

FAQs

Answer: The level of calcium inside an aquarium should be around 400-420 ppm. If the calcium level deviates from this range then the health of the corals and invertebrates will be at stake. 

Question: Will raising calcium levels to lower the alkalinity?  

Answer: Yes, adding in too many calcium supplements can lower the level of alkalinity. This is because you’ll get calcium carbonate precipitation below the tank. As a result, the alkalinity level gets lower every time you add in calcium. And, the same happens when you add in alkalinity supplement as the level of calcium reduces then. 

Question: Should calcium levels be high in a reef tank? 

Answer: No, calcium levels should be in range on a reef tank. If the levels of calcium are too high then it’ll cause precipitation of the alkalinity. As a result, you’ll have a difficult time increasing the level of alkalinity. 

Question: Will calcium at extreme levels kill fishes and organisms? 

Answer: Yes, calcium at an extreme level can actually kill the organism and fishes inside an aquarium. So, it’s better to keep the levels in check.
