Cleaning Pond Rocks and Evaluating the Eco Aqualizer Ionizer

Jacqueline has made significant improvements to her inherited pond: added a Savio biofilter, Microbe-Lift PL, wheat germ pellets, and daily rock raking. Water clarity improved, but algae persists on waterfall rocks. She plans a full clean-out using a tractor, pressure washing, and saltwater rinsing. She also asks about the Eco Aqualizer molecular ionizer for algae control.

Expert Analysis of the Eco Aqualizer

Robyn, a chemist, investigated the product and found its claims scientifically dubious. The device allegedly ionizes water to produce oxygen, hydrogen, and possibly hydrogen peroxide. However:

• Oxygen levels in well-aerated ponds are already near saturation; excess oxygen simply bubbles out.
• Hydrogen peroxide can kill algae but harms fish at high doses.
• Barley straw naturally releases low levels of hydrogen peroxide as it decomposes.
• A chemistry reference site states "ionized water" is a meaningless marketing term.

Practical Advice

The Eco Aqualizer likely won't harm the pond but may not provide benefits beyond proper aeration. Robyn suggests joining a local koi club for hands-on help and focusing on proven methods: good filtration, regular maintenance, and balanced plant life.
