Fighting mustard algae, too

[southside]

Thanks for the quick reply, PoolDoc!

I have submitted a Pool Chart Form ... basically 12' x 36" Intex round with Intex 635 pump and type A filter. It's about 1800 gallons of water - so I'm double checking on the amount of plain bleach you want me to add this evening. I tested the chlorine using the FAS/DPD method and it has come down to 46.25 ppm (from yesterday's 57). pH 7.5 and TA 250. Based on those readings, how much plain bleach do you suggest I put into the mix? Thanks
