Fritz Reef Pro MixRPM)海盐混合物由于价廉物美,迅速成为美国最受欢迎的海盐混合物在各地的珊瑚礁水族店中广泛使用。包括我们自己在内的大多数RPM老用户都对这种盐混合物表示赞赏因为它能够维持钙、镁硬度平衡Fritz一直在开发一种名为RPM High Alk的新版海盐,它提高了浓度增加了缓冲元素。

 

根据自身的珊瑚礁养殖经验,我更喜欢使用最天然的海盐混合物,即那些接近自然海水成分的混合物。这对绝大多数鱼缸和珊瑚来说都是不错的选择,但对于充满生长快速的石珊瑚的水族箱来说,浓缩的配方可以保持珍贵的矿物质平衡。

SPS珊瑚(例如这些带金属光泽的表孔珊瑚)快速生长时,对钙和碳酸盐的需求极大,难以满足

 

一个60加仑227珊瑚SPS珊瑚发生爆炸性增长,对主要元素(主要是构成碱的元素)的需求增加,因此突显了更高浓度的海盐混合物的价值。目前这个系统每两周要消耗大约一升高浓度缓冲液,才能保持7dKH的碱度。

 

与部分珊瑚养殖者一样,给水族箱换水是我日常维护工作的重要一步,因此用新盐水改变水质提高碱度这个想法听起来很不错。当然,很多商业珊瑚养殖者和交易商也喜欢使用经济实惠的海混合物来提高碱度,例如本身碱度为10~12dKHRPM High Alk海盐

 

 

 

Fritz Reef Pro Mix (RPM) High Alk Formula Coming Soon

Fritz Reef Pro Mix (RPM) has quickly become one of the most popular seawater salt mixes in the United States, both for its consistency, affordability and the simple fact that it is becoming widely available at finer reef aquarium stores everywhere. Most veteran RPM users, ourselves included, have appreciated the balanced levels of Ca, KH and Mg that this salt mix provides but Fritz has been developing a new version called RPM High Alk which provides a higher concentration or buffering elements. 

 

For much of my reefkeeping experience I’ve leaned towards the most natural seawater salt mix, that is those which mix up to be as close to natural seawater levels as possible. This is fine for the vast majority of fish and reef aquariums, but for those setups that are chock full of fast growing stony corals, ‘enriched’ formulas can help to keep our precious mineral balance pegged. 

 

When they are growing fast, SPS corals such as these plating Montipora can have an insatiable demand for calcium and carbonate

 

The value of a higher alk salt mix has become more apparent as one of my 60 gallon reef tanks has seen explosive growth of SPS corals within it, and an accelerating demand for major elements, most prominently those that constitute alkalinity. At present this system is consuming around one liter of high concentration buffer every two weeks, and it’s all I can do to maintain an alkalinity of 7dKH. 

I’m one of those reefers that uses water changes as an essential part of my maintenance routine so the notion of being able to do water changes with new salt water that will help increase alkalinity is very attractive. Surely a lot of commercial coral growers and dealers will also appreciate using an affordable seawater mix such as RPM high alk with a ‘native’ alkalinity of 10 to 12dKH.
