Opportunities and challenges for the Libyan geological
These resources are located exclusively in northern and west central Libya; however, other minerals such as lead, iron, copper, and gold occur also in southern Libyan territory. This disparity in the spatial distribution of mineral resources can be explained by two facts: (i) the geo-resources in southern and eastern Libya are absent/scare or ...

Phosphates
Phosphates are algae food. If you kill all the algae, phosphates do not matter. Be aware that Pool Store phosphates tests are not that good and they will try to sell you cheap phosphate removers even with very low phosphate levels. If you are concerned about phosphates, get the Taylor K-1106 test kit.

Minerals and Mineral Groups | Earth Science
Sulfides are formed when metallic elements combine with sulfur. Unlike sulfates, sulfides do not contain oxygen. Pyrite, or iron sulfide, is a common sulfide mineral known as fool's gold. People may mistake pyrite for gold because the two minerals are shiny, metallic, and yellow in color. Lesson Summary

Iron Phosphate General Fact Sheet
Iron phosphate is practically non-toxic to birds, based on testing with quail. Beetles and earthworms were not affected in studies using twice the amount of iron phosphate allowed. Iron phosphate is practically non-toxic to fish, water fleas, and algae. Exposure to bees is unlikely because it is applied to soil as granules.
