The CYA Trade-off

For every 1 ppm of chlorine added by Dichlor, you also add 0.9 ppm of stabilizer.

Actionable Steps

Shocking with Dichlor

Dichlor is fast-dissolving and pH-neutral, but it increases your CYA level.

⚠️

Safety Warning: Monitor your CYA closely. If it gets too high, you must drain some water.

Pro-Tip

Dichlor is 57% chlorine but contains 43% stabilizer (CYA). Use it sparingly to avoid 'Chlorine Lock' where CYA becomes too high.
