Questions & Answers

Fluval Marine Salt features strong levels of calcium and magnesium. Do I still need to supplement those elements?

While Fluval Marine Salt is reef-capable, additional calcium and magnesium supplementation may be required depending on the quantity and variety of calcium and magnesium-consuming organisms in your tank – namely, corals and coraline algae.

Using RO water, I mixed in your salt and noticed my pH was 8.1 to 8.2 after only a few minutes. Can I introduce the mixed water right away?

Yes. Fluval Marine Salt becomes clear in the first few minutes, and maintains a safe, stable pH of 8.1 to 8.2.

Why does my salt mixing bucket have beige-colored deposits on the sides?

This is likely the result of using tap water or highly alkaline water, which can cause some precipitation when mixing with salt. Unless you see waste material or discoloration within the salt itself, it is likely not the problem.
