SLAMing new water. SLAM before increasing CYA?

Had to drain/fill due to very high CYA and mustard algae. Should I SLAM before bringing my CYA up to recommended? It's essentially 0 now. Assuming that will save me some chlorine during the SLAM process?

Yes, you should get your CYA up to a minimum of 30-40PPM. It will probably cost you in LC purchases in the process if you dont because the sunlight will eat up the FC quicker, thus needing to add more LC.

SLAM - Shock Level and Maintain

We’ve all had to deal with a green pool. Clear algae from your pool with a SLAM! Read here to use shock level and maintain to clear your pool.

Agreed. Be sure to have at least 30 ppm of CYA before increasing the FC to SLAM level. Chorine is exponentially more strong with no stabilizer buffering protection.
