My salt mixing buckets have beige-colored deposits on the sides. Why?
This is likely attributed to using tap water or high alkaline water, which can cause some precipitation when mixing with salt. It is not a problem attributed to the salt, unless you see waste material or discoloration within the salt itself.
After adding salt to my reef aquarium, the specific gravity reading from my hydrometer was very high. What should I do?
Make sure you tap the hydrometer thoroughly to dislodge any air bubbles from the armature. If tapping doesn't help, insert a thin object in the hydrometer and tap the armature directly to release any lodged bubbles.
I just started using Fluval SEA Marine Salt, and I noticed my pH is 8.1 to 8.2 after a few minutes of mixing. I use RO water and the water is clear after that short mixing time. Can I use the resulting marine mix within the first 10 minutes?
Yes, you can. Fluval SEA Marine Salt mixes clear in the first few minutes, and should give you a safe stable pH of 8.1 to 8.2.
