Frequently Asked Questions

How do I choose the right sea salt for my reef tank?

For SPS-dominant reefs, we recommend SPS Sea Salt due to its high calcium and alkalinity stability. For mixed reefs, Reef Sea Salt offers a balanced profile with enhanced trace elements.

Can I use Tropic Fish Sea Salt in a reef tank?

Tropic Fish Sea Salt is optimized for fish-only systems. While safe for invertebrates, it lacks the elevated calcium and trace elements needed for coral growth. Use Reef or SPS formulas for reef tanks.

How often should I test water parameters after mixing?

Always test salinity with a refractometer after mixing. Check calcium, alkalinity, and magnesium weekly in established reef tanks to maintain optimal levels.

Are your supplements dosed daily or weekly?

Bio Calcium, Magnesium, and KH supplements are typically dosed daily based on consumption. Trace Elements can be dosed weekly. Always follow dosage guidelines and test regularly.
