Poolife® Back to Blue™
Product Overview
Green-pool recovery jobs call for a fast-dissolving, high-concentration shock system that handles both sanitation and flocculation.
In our experience, the Poolife Back to Blue system is a proven choice for restoring clarity to algae-infested water using a 4.6 lbs kit containing 78% Calcium Hypochlorite. This two-part system reliably handles severe blooms by first killing bacteria and algae with Step 1 (2.6 lb) and then dropping the debris to the floor with Step 2 (2 lbs) for easy vacuuming to waste.
Benefits & What Makes It Different
78% Available Chlorine
This high-strength Calcium Hypochlorite formula provides a powerful sanitizing punch without adding Cyanuric Acid (CYA) to your water.
Two-Step Flocculating Action
Unlike standard shock, this kit includes a 2 lbs second stage designed to settle suspended particles to the pool floor overnight.
Rapid 24-Hour Recovery
The standard specification for this product allows homeowners to move from a green swamp to a blue pool within a single day when following the vacuum-to-waste protocol.

When To Use This
Pro Tip
In hard water areas like the Southwest, monitor your calcium hardness levels after using Cal-Hypo products, as they can contribute to scale if levels exceed 400 ppm.
Common Questions & Instructions
How much Poolife Back to Blue do I need for a 15,000 gallon pool?
For a 15,000 gallons pool, you use the entire 4.6 lbs kit: first add the 2.6 lb container of Step 1 to sanitize, then follow with the 2 lbs container of Step 2 to settle debris.
Can I use this product if I don't have a multiport valve?
This system is specifically designed for filters that allow vacuuming to waste; if you cannot bypass your filter, the 2 lbs of sediment from Step 2 may clog your cartridge or sand bed quickly.
Does this product increase stabilizer levels?
No, because the active ingredient is 78% Calcium Hypochlorite, it does not add Cyanuric Acid (CYA), though it will slightly increase calcium hardness levels over time.
