Maintenance

I use no mechanical filtration what so ever, so no cleaning of filter socks or sponges.
Refilling top-up reservoir about every 3-4 days.
Cleaning Glass every 2 Days.
Cleaning Skimmer Cup about every 6 days.
Active Carbon every 4 weeks for a few days (400ml).
Algae in refugium takes care of most No3 and Po4.
If needed Po4 Remover. Alternating between Aluminium- and Iron-based so that not too much of the aluminium or iron akkumulates in the water.
Water changes only when a big error occures.
Water parameters checked in Laboratory about every 3 Months.
Water testing with Testkits almost every day: Salifert for Ca, Mg, KH. Red Sea for No3. Hanna checker for Po4. I use the Phosphorus checker and calculate Po4. This gives a much more precise reading.

The TDS i use for Second Salitity Measurement because my Apex Data uses the Salinity Measurement. I measure with a precision hydrometer.
If the noted reading is 23,8 then it is actually 1.0238 d
