Water clearing agents and how they work
Generally flocculents should not be used in tanks with fish.Flocculents are positively
charged compounds that bind negatively charged particules so they bind together
and fall out of solution resulting in clearing.Since algae cells are negatively
charged Flocculents will clear green water.
Theres a possible problem tho,the gill surfaces of fish also carry a negative
charge.The Flocculentscan bind the gill filaments together destroying the gill
structure.
