Pre-portioned alkalinity 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 alkalinity aquarium supplement.
  • Best used as part of our 2 part system, but can be used alone.
  • Maintaining alkalinity is a required part of proper aquarium maintenance. It is necessary to support the aquariums pH, and the healthy growth of coral skeleton.

Mixing Directions: Dissolve the entire contents of one pouch in a 1 gallon dosing container filled with pure water. Extensive mixing is normally required in order to fully dissolve the powder, and warming the container in water will help speed up dissolution.

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