Pre-portioned calcium mix for use with the Shlobster 3 part system.

We won't claim to have reinvented the wheel, or engineered a revolutionary chemical formula in order to provide our awesome 2 part solution to you.

What we have done though, is arranged the correct grades of additives you need to reliably maintain your calcium, alkalinity & magnesium levels - on the cheap, and without the contamination that lower grades of additives can contain.

We know the level of success (especially with hard corals) that can be attained with proper maintenance of these minerals and are excited to help you get that done.


  • Makes 1 gallon of calcium aquarium supplement.
  • Best used as part of our 2 part system, but can be used alone.
  • Calcium needs to be readily bioavailable in order for many aquarium inhabitants to grow at a healthy rate.

Mixing Directions: Dissolve the entire contents of one pouch in one half of a gallon of filtered water. Caution: Solution will become hot while mixing! Pour the mix in to the dosing container and bring the total volume to 1gal. Let sit several hours before use.

Dosing Directions: Begin dosing at the rate of 2.5ml per 10 gallons daily to an area of high flow. Dosage is based on alkalinity demand. Test alkalinity every few days and adjust accordingly. Always add the same amount of part A & B, but at different times.
