Product Information

Full details

The Reef Zlements Part 2 Universal is a professional-grade additive designed for reef aquarium hobbyists looking to maintain essential calcium and trace element levels for optimal coral health. It serves as a vital component in a balanced 2-part dosing regimen, offering high-concentration support for vibrant growth; however, it requires careful, timed application alongside Part 1 to prevent chemical precipitation in the water column.

FAQs

Can I use Part 2 without Part 1?

No, it is designed as a 2-part system where Part 1 and Part 2 complement each other to balance the aquarium chemistry.

How do I know how much to dose?

Test your calcium level, wait 24 hours without dosing, test again to find the daily drop, and adjust your dose to match that consumption.

Does this replace the need for water changes?

While this replenishes essential minerals, regular water changes are still recommended to export waste and maintain overall water quality.

Is this safe for all coral types?

Yes, it is formulated to support stony corals (SPS/LPS) that require consistent calcium and trace element levels for growth.

What is the shelf life of this product?

When stored in a cool, dark place, the solution remains stable for its indicated shelf life, but always check for signs of crystallization.

Troubleshooting

Calcium levels remain low despite dosing.

Increase the daily dose incrementally and test again after 48 hours to allow the chemistry to stabilize.

White residue or cloudiness appears during dosing.

This is likely precipitation. Ensure you are spacing out the dosing of Part 1 and Part 2 by at least 15 minutes and dosing into a high-flow area.

pH levels are fluctuating.

Check your alkalinity levels; ensure your 1:1 dosing ratio is correctly balanced to keep both calcium and pH stable.

Pros and Cons

Pros

  • Highly concentrated for cost-effective, long-term use
  • Promotes vibrant coral coloration and structural growth
  • Includes essential trace elements beyond just calcium
  • Easy to integrate into existing automatic dosing systems

Cons

  • Requires strict adherence to 15-minute separation from Part 1
  • Needs regular water testing to calibrate dosing amounts
  • Must be dosed in a high-flow area to avoid localized precipitation

Setup, Compatibility & Care

To set up your system, ensure you have both the Part 1 (Complete) and Part 2 (Universal) solutions. The system is most effective when used with an automated dosing pump for consistent delivery.

  1. Ratio: Begin with a 1:1 dosing ratio of Part 1 to Part 2.
  2. Timing: Program your doser to dispense Part 1, then wait at least 15 minutes before dispensing Part 2 to prevent chemical reaction and precipitation.
  3. Monitoring: Test your water weekly for calcium, magnesium, and alkalinity levels.
  4. Storage: Keep the bottle sealed in a cool, dry area away from direct sunlight to maintain the integrity of the trace elements.
