Technical Fact

Flow rate through a skimmer should not exceed the equivalent of the volume of the contact chamber being exchanged in less than one minute. Recommended system turnover through the skimmer should be at least 1x total system volume per hour.

Ozone should be applied on an individual tank basis at the equivalent of 5–15 mg/hour per 100 litres of volume. In commercial applications, 0.05 mg ozone per litre of flow is sufficient to achieve a recommended redox of 300–400 mV. A much higher dose rate of 0.2–0.5 mg of ozone per litre of flow is required to achieve redox levels of 700–800 mV at which the water can be considered sterilised but unfit for livestock without further treatment.

Maintenance Tip

All TMC Protein Skimmers (including those installed on complete filtration systems) come with an internal and external rinsing fittings to keep the skimmer clean and scum-free at all times. Regular washing and rinsing inside the skimmer prevents the build-up of fatty deposits and keeps the skimmer working efficiently. An automatic battery timer valve can be installed on each of the internal and external washers to routinely and automatically rinse down the skimmer cup.
