EDTA binds metal ions into stable compounds that are far less toxic to fish — lowers iron and acid-sulphate metals, neutralises toxins in the water and reduces hardness so algae grow more easily.

4 main benefits
- 01
Binds metal ions into stable compounds, lowering their toxicity to fish.
- 02
Reduces iron, aluminium, manganese, lead and similar in the water, and limits metal deposits on fish gills when using groundwater or after rain washes them in from the soil.
- 03
Effectively neutralises toxins in the water such as snail killers, pesticides and copper sulphate.
- 04
Reduces water hardness so algae develop more easily.
Locks up metals and toxins before they harm fish
Well water, rain run-off and acid-sulphate soil bring iron, aluminium, manganese and more into the pond, coating fish gills and slowing growth. PREMIX EDTA binds those ions into stable, low-toxicity compounds.
