The Colombian Zebra Pleco will not bother most plants and it is not an effective algae-eater

Salinity Refractometer filters pH: 6It is designed for testing the concentration of salt water and brine and used for quality control in research and clinical laboratories and marine industry. Its scale provides a direct reading of the specific gravity and concentration (part per Thousand) of salt in water. One scale checks the NaCl levels with the range of 0 100 ppt (with 1 ppt scale divisions) and the other scale gauges Specific Gravity with a range of 1. 000 to 1. 070 (0. 001
