My DT with Refugium is a total of 280 gallons. I use the following:
Dosing with:
- Calcium
- Magnesium
- Strontium
- Pottassium
- Trace Elements
- Zeovit (Coral vitalizer, Amino Acid, Iodide Complex, Potassium Iodide Flouride Concentrate, Coral Snow, Zeo Spur 2, ZeoFood and ZeoBak)
Also using rowas in a fluidizer also carbon in a larger fluidizer
Of course, you need to test if you are going to this extreme. I test all parameters before dosing.
