Crystal Shrimp Pro soft water, thermometer

Crystal Shrimps are a delight and are highly priced as pets.  They are a challenge to aquarists and hobbyists due to their sensitivity to water conditions.  The Crystal Shrimp Pro is specially designed for the successful keeping of Crystal Shrimps. 

The market commands a high price for these shrimps as the red signature takes a few generations of selection due to the breeding cycle.  Another reason for the high price is transportation and express quarantine due to sensitivity of water conditions. Usually after transportation, a high percentage would not survive.

The Crystal Shrimp Pro is dedicated to measure the important water softness and temperature.

Why do we test water softness?
Water softness is an important parameter for crystal shrimp.  Caridina family like Bee Shrimp, Amano Shrimp, Red Cherry Shrimp etc. have similar requirements.  Although these shrimps can survive well in moderately hard water, they cannot survive well in water that is too hard or soft.  Each species thrive in slightly different hardness ranging from 3 to 15dH.

Why do we test water temperature?
Temperature is another important factor affecting the shrimps.  The ideal temperature is slightly lower than the tropical temperature of around 20 to 25oC.  Depending on the species, they will not survive above these ranges without strong aeration and non-overcrowding.  Temperature swings will cause mare casualties.
