Tropic Marin 10325 Bioactif Sea Salt 200gal

Bio-ACTIF SYSTEM is suggested for aquarists that want all of the benefits of Pro-REEF but also want to add carbon dosing to their tank maintenance regime. Bio-ACTIF SYSTEM salt has the same calcium and magnesium levels as Pro-REEF with a slightly higher alkalinity: 7.5-8.5 dKH and has the addition of the same carbon dosing compounds (long chain marine polymers) found in Tropic Marin's Reef-ACTIF product and Bio-ACTIF SYTEM line of products. Made with all pharmaceutical grade raw materials, it has zero nitrates, phosphates and silicates. It always dissolves cleanly and crystal clear with no residue and is produced in our lab under the strictest batch controls.
