D-D H2Ocean H2Ocean P4 Dosing Pump Hard Coral Chromium is a trace element

Chromium is a trace element present in small quantities in the seawater of reefs all around the world

The algae growth is first brought to a standstill and then it disappears

This prevents the collection cup overflowing if the water level in the protein skimmer rises due to the sump water level suddenly increasing

This allows you to have a calmer constant flow pattern during the night as aquarium inhabitants rest and the full energy random flow at the peak of the day or any combination in between

The footplate design offers a new approach to water flow inside the skimmer giving better contact time between the air/water mixture without increasing the overall height of the skimmer
