Mustard algae maintenance

[Silverflampond]

I am in the processes of SLAMing my pool after a mustard algae appearance (color and location match the description here: Mustard Algae).

I am inquiring about FC maintenance here:Chlorine/CYA Chart.

In that second post, the Yel/Mstrd Min column - how long should I follow this, or, given that I have encountered this problem two years running, I should expect this to be the regular approach? Both appearances were after a week trip away where the pool was improperly maintained.

I have followed all guidelines (SLAMing, brushing, cleaning items, and so on) and kept chlorine at an appropriate level before the outbreak. I use the guidance here, not a pool store and have a TFP test kit.

Current numbers are not relevant because I am in the middle of Yel/Mstrd SLAM after doing SLAM with a clear pool and less than 0.5 ppm chlorine drop.

Thank you.

Some people need to maintain MA minimum for the rest of the season- some choose indefinitely others for just a short time. Each circumstance is different.
Make sure you were thorough with your regular slam to ensure you got it all.
You are done when:

CC is 0.5 or lower;
You pass an Overnight Chlorine Loss Test
AND
The water is clear.
(Crystal Clear w/no algae dead or alive)

*Check & scrub every nook & cranny where algae may hide (light niches, steps, drain covers, ladder handrails, skimmer throats/weirs, abandoned lines, autofill, overflow drains, etc.)
*If water can go there, algae can thrive there.
*Run slam level water through all water features & lines for at least a couple hours a day during the SLAM Process.
*Brush & or vac daily (this breaks up biofilms that algae uses to protect itself from chlorine)
*Backwash/clean filter when pressure rises 25%over clean pressure.
