NYOS Calcium Reefer - High Precision Test for Calcium (CA) CALCIUM REEFER NYOS® REEFER test kits - taking measurements at the laboratory level at an attractive price Water properties as close to nature are the key for every aquarium's success. However, monitoring relevant parameters in seawater is difficult due to numerous interfering ions. Therefore, test kits considering the specific characteristics of seawater are needed to analyse the water precisely. NYOS® REEFER test kits offer the customer two significant benefits: Highly precise analyses for seawater conditions. Furthermore, they offer a highly attractive price-performance ration and make test kits in laboratory quality affordable for the standard hobby user. Additional characteristics of our REEFER test kits: calibrated dropper made by a German manufacturer ensures uniform drops during all repeat tests reagents are made in Germany in accordance with EN ISO 9001 reagents are analysed according to AAS and NIST standards strict batch and quality control easy to use with intuitive pictogram instructions Made in Germany NYOS® REEFER test kits allows you to achieve precise and most importantly reproducible (i.e. in repeat measurements identical) measuring results.

I have a nano tank for a year. Like any new hobbyist, I often envy the display tanks at the aquarium shops. Even their nano tanks looks 100 times better. You buy a coral and when you put it in your own tank. It flourishes a while and then it becomes smaller and lacks its former beauty and brilliance. Well, the LFS owners run a business and we do it as a hobby. And their tanks are mature and have been around for years. Fair point. But wont it be nice if we can do the same. I do water quality test on ammonia, nitrite, notrate, copper, phosphate, PH and trying to get the ideal water condition and I have no idea how many "magic" additives I have bought. It is like golfer with their new clubs. Yesterday I tried something new and crazy. I dropped half of the GNC Magnesium and Calcium vitamin pill into the tank. The calcium caused the tank to be slightly cloudy but it cleared up in 5 minutes. Then I noticed the mushrooms began to open up till they covered the rocks and everything seemed to go hyperdrive in terms of size. It is like they were given steriods. I did some research and found out that magnesium is important to corals and fishes, the third most common ion (or element) after sodium and chloride (guess that is why it is called salt water). And most artificial salt and artificial seawater lack the magnesium. The chemistry is pretty complicated and I am no chemist. Summary: some artificial sea salt has plenty of magnesium and some dont. I am sure someone has tried this before. But it works for me. It is too early to tell if this is the solution as I would need more test over time. Perhaps it is the calcium and not the magnesium. Or is it a fluke result? Maybe some seniors in this forum can shed some light but it is fascinating if this really works! Exclusion Clause: Do this experiment at your own risk. Maybe dont even experiment until it is proven safe. Maybe everyone knows this trick. Any advice?
