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 guys, Am just wondering how have you been maintaining your Kh. I have a calcium reactor and managing it well maintaining at 420-430 range. My concern is now my KH . I have a Kalk reactor as well and use grotech carbonate . As it is in powder form it gets dissolved easily and it seems the whole bottom lasts between 4-6weeks tops. Though it gives me good reading maintaining at 8-9 ...errr Question is , just like calcium reactor where you just set it and let it run for a lonnnnggg time without touching it, are there better ways to put any other type of product that could last longer ?? I'm clearly aware of bicarbonate soda and am not looking at short term gain but long term run. Advises appreciated . Thank you !
