So how to lower magnesium in reef tank. Its kind of tricky but i will explain that in a explainable way. Some seaweed products and waffles are rich in magnesium. When not consumed, they dissolve in water and increase magnesium levels. So how can you reduce magnesium levels in a reef tank. The decrease in magnesium content is the easiest parameter to control of all the other parameters. In most cases, a simple water change is enough if we do it correctly. But if changing the water doesn’t help, there are other little tricks. We can filter it with chemicals like calcium hydroxide. But this approach has side effects.
How to lower magnesium in reef tank – What is the right level of magnesium in a reef aquarium?
We rarely need to worry about high levels of magnesium. Indeed, sea water is rich in magnesium. For this reason, aquatic species are accustomed to high levels of magnesium.
A more common problem is low magnesium. Fish and corals are the most affected by this factor. When this happens we should look for magnesium supplements to increase magnesium levels in the reef aquarium. As long as the concentration is below 2000 ppm, we are safe. So until then, we don’t have to try too hard to lower our magnesium levels. It’s now generally recommended to keep magnesium levels under 1500. So if it’s not over 2000, why don’t we push it.
When the level is below 2000, we just need to give our tank time. Indeed, over time, magnesium is depleted in a day or two. Aquatic species can tolerate this level of magnesium for short periods. Magnesium levels will not exceed 2000 ppm unless we add something extra to the tank. When it exceeds this level, we should start to worry. Solutions to Reduce Magnesium Levels Magnesium is one of the most important water parameters to control. Don’t worry if our magnesium levels are too high! We offer three solutions to achieve your ideal magnesium content.
Get the right test suite
This is the first step. Often we don’t get the right set of tests. This led us to collect erroneous results regarding magnesium levels. So when we go to the aquarium, make sure you’re not a cheapskate. No matter the price, we have to get the best in the store. Buy these things once or twice in your life. So it is better to buy the best.
How to lower magnesium in reef tank – water change
If the level is above 2000, the water can be changed with a low-magnesium salt mixture. Water changes can be between 60% and 90%.If you’re not sure which salt blend to use, choose a low-magnesium salt blend. Believe me, you can choose any of them. As such, they will serve our purpose of changing the water well. After a water change, do not be in too much of a hurry. The next thing we need to do is wait patiently for some time. Magnesium levels drop quickly on their own.
How to lower magnesium in reef tank – Using Chemical Methods to Reduce Magnesium
If we don’t like the natural method by changing the water, we can use this method. Recommended if you want to reduce the level in a short time. This is especially appreciated by those who have a variety of corals in their reef tank. Corals are too sensitive.
Moreover, this method is not always recommended. This approach leads to an increase in calcium levels. In some cases, it also causes an increase in alkalinity.So while doing this process we must use good calcium test kits as well as alkalinity testers. This will help us control the calcium and alkalinity levels on the micro controller.
When sucking magnesium from an aquarium, it is recommended to avoid any calcium supplement. Now let’s move on to the main process. All we have to do is run the aquarium water through the calcium hydroxide reactor. In this way, magnesium hydroxide, which is insoluble in water, will precipitate. Therefore, the water will be deprived of additional magnesium. Then we have to filter the water through a fine pore nasal filter to collect the sediment.
