Frequently Asked Questions

What is the difference between Reef Sea Salt and SPS Sea Salt?

SPS Sea Salt is further purified from Reef Sea Salt and specially formulated for the growth and breeding of Small Polyp Stony corals, which require higher water purity and specific trace elements.

How often should I test salinity?

We recommend testing salinity weekly using a calibrated refractometer. Our Hand Held Refractometer HZY030 offers accurate readings with automatic temperature compensation.

Can I use Tropic Fish Sea Salt for reef tanks?

While safe, Tropic Fish Sea Salt is optimized for fish health. For reef tanks with corals, we recommend Reef Sea Salt or SPS Sea Salt for better trace element balance.

How do I control nitrite and nitrate in my tank?

Maintain nitrite below 0.3 mg/L using biological filtration. Use NP BioPearls to reduce nitrate and phosphate. Test regularly and perform water changes as needed.
