Why Do You Need a TDS Meter?
OK, first of all; let’s talk about TDS. Well, it stands for “Total Dissolved Solids.” Which means the TDS Meter measures the amount of inorganic element in water such as salts, metals, and minerals (other than water molecules.) In other words, the meter measures negative and positively charged ions in water. The meter gives readings in ppm (parts per million) or mg/liter. The measurement allows us to know the purity level of water. So, it allows you to determine the effectiveness of a water purification system.
Well, you can use a TDS Meter in your home to measure the purity level in tap water you drink. Aquarists use it often to measure the water quality before the fishes go in a tank. It’s a good way to ensure whether the water is safe for the creatures. As you already know, fishes are delicate creatures; so water quality and impurity levels directly affect them.
OK, now let’s talk about the tap water we drink. Do you think the tap water is 100% pure? No, it’s not. Even though the water purification plants purify the water, it can contain impurities. Well, the water coming from the purification plants may have fewer impurities, but pesticides and chemicals can get into the water due to many activities such as land runoff, industrial activities, and sewage. That’s why we should filter tap water in homes before drinking. Anyway, we can’t see the impurities with the naked eyes, so a TDS Meter is a handy tool for the task.
If you are a fish owner, then you know the importance of maintaining water quality for the safety of the fishes. As mentioned, the tap water you get from a purification plant may not harm you. Anyway, tap water can harm sensitive fishes. The TDS levels in tap water may vary from country to country. For example, UK tap water has a value 100-500 ppm (safe for human consumption.) A TDS Meter is a very useful instrument, yet very cheap. You can buy a meter for $15 on eBay.
People often have doubts about the TDS readings. Well, I can say; lower TDS values are much safer than higher values. Since many factors affect the reading, TDS level can fluctuate often. Follow this link to see a meter and how to use it on tap water Do you have a water filter in you home? If you have a one, you can use a TDS Meter to determine the effectiveness of the filter. Use the meter and determine the TDS of tap water. Then measure TDS of filtered water. Now compare the results. So, is your water filter doing its job properly? Industrial water purifying units are very effective, and the ppm of water you get from them can take a value less than 5. This water is safe for sensitive fishes.
Tips for using a TDS Meter:
* Don’t touch/damage the electrodes.
* Keep the electrodes clean.
* When you measure a water sample, make sure you use a clean vessel/bowl (the impurities in the vessel could be the reason for different readings.)
OK, great. Hope you found this article helpful. TDS Meter is a digital device, so maintain it will for long life and accurate readings.
