R/O Right

Detailed Review

Kent R/O Right dates back to when RO water use in freshwater aquariums was becoming popular, but before the shrimp keeping hobby had developed specialized products. For many years, it was one of few options available for remineralizing RO water. The formula was designed for general freshwater use - fish, plants, and invertebrates. It raises both GH and KH using a mix of minerals including sodium chloride. In the context of its time, this was perfectly adequate. Modern shrimp keeping has moved beyond this. Products like Salty Shrimp, SL-Aqua, and others were specifically developed for shrimp, with carefully balanced calcium-to-magnesium ratios, sulfate-based minerals instead of chlorides, and formulations tested on shrimp populations. Some hobbyists who started keeping shrimp in the early days still use Kent R/O Right out of familiarity and habit. If their shrimp are thriving, there's no urgent need to change. But for new keepers starting fresh, modern products offer meaningful advantages. The sodium content is a particular concern. While not immediately harmful, sodium accumulation over time is an unknown variable that shrimp-specific products eliminate by using sodium-free formulations. Verdict: A product of its era that still exists but has been surpassed by purpose-built shrimp products.
