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.

Hi all, Just upgraded to a 6-footer. Running a calcium reactor. Tested the water after one week, and was shocked to find Ca level of 261 (Hanna kit). Couldn't believe it so did an immediate retest. Got 316. kH was 9. I've never seen such low Ca in any of my set ups. Any idea what is causing this? I've dosed with liquid calcium, and will do a retest same time tomorrow. Hopefully this is just a temporary glitch.

On November 15, I have purchased almost full setup of Brand new marine tank equipment (tank, wavemaker, return pump, tester, ATO, skimmer etc..) directly from shop with the intention of starting marine tank around Jan 16. Due to family commitment, I need to give up my hobby and willing to sell all the BRAND NEW ITEMS with warranty at discounted prices lower than the shop. This will be the first part of my sale. Please stay tune. Kindly contact my mobile 911167zero5 if you are interested. Dealing at west boon lay.
