Salifert Magnesium Marine Water Test Kit

Salifert Magnesium Marine Test Kit is used to measure magnesium levels in marine aquariums to help maintain the correct balance of calcium and alkalinity for optimal coral and calcareous algae growth.

Magnesium is present in NSW in a fairly high concentration (1300 - 1400 mg/L). Magnesium is an essential part of chlorophyll, which is necessary for photosynthesis. Without photosynthesis plants, including algae and the corals, which we usually have in our aquariums, would not be able to live.

Magnesium has another important function since in fact makes maintaining the correct combination of calcium concentration and alkalinity or carbonate hardness possible.

The explanation is as follows. Calcium forms with carbonates and bicarbonates an insoluble compound called calcium carbonate. Yes, this is indeed an important building stone for corals and calcareous algae but then it should be formed by biological processes and be deposited at the right place. Therefore formation of calcium carbonate by chemical processes should be avoided.

Even without biological interference calcium carbonate would be formed and would deplete calcium and alkalinity or carbonate hardness without fulfilling any function. In fact it will scavenge many important trace elements as well lowering the trace element concentration.

Magnesium slows down this negative process. The lower the magnesium concentration the faster this negative process will take place and also at a much lower calcium and alkalinity/carbonate hardness value.

Maintaining a correct magnesium concentration is therefore very important and is indirectly responsible for fast coral and calcareous algae growth by virtue of making the maintenance of correct calcium and alkalinity figures possible.

Magnesium is depleted by algae and is also depleted by the use of excessive kalkwasser and by going far beyond natural calcium and alkalinity and pH values.

There are also certain brands of salt, which have or had a dramatically low magnesium content. The use of such a salt will result in permanent problems with calcium and carbonate hardness values.

Conclusion:

The measurement of magnesium and taking corrective measures are justified. Magnesium additives should be such that no ionic imbalance is created. Furthermore, many magnesium salts contain sufficient amounts of ammonia to upset biological balances. Very high-grade magnesium salts are therefore required.

Magnesium is an element that has been neglected for a long time. The magnesium content of some aquariums appears to be rather low when tested. Corrective measures have to be taken for a balanced reef system.

The Salifert magnesium test is very straightforward and does not suffer from calcium and strontium interferences when within certain bounds. It measures in sufficient accurate steps of 30 mg/L with a sharp color change. The kit can perform approx. 50 measurements.

Perfect for playtime and exercise
Color: White
I’ve been using this automatic dog ball launcher since the day I received it, and it has honestly been amazing for both me and my dog. My pup took to it surprisingly fast, and now he plays with it every day without getting bored. I love the adjustable distance settings because I can use it indoors or outdoors depending on the weather. The toy is a very good size and quite practical. In the days I’ve been using it, the product's quality has really stood out, as it has proven to be highly effective. I believe it offers excellent value for the quality, and I recommend it if you are looking to keep your pet entertained.

Do Not Use The Balls That Come With It!
Color: White
This ball machine shows 6 meters or 19 feet. Unlike other ball launchers this is too powerful for indoor use. But I found that if you use different balls through experimentation then there are some that do not go as far.

100 de 100 fabuloso
Color: White, Color: White
The best gift for my dog! I absolutely loved the design and its features—I can adjust the ball-launching distance, and the fact that it’s rechargeable is fantastic. The material of the balls is durable, too. My dog’s name is Oreo; I set up his toy in the yard, and it was so much fun watching him play outdoors. I’m currently teaching him how his new toy works. I highly recommend this for our four-legged babies—5 stars!
