Killing Black Algae

[clw72]

Hello, I have a question about running the pool pump while killing black algae. FC is 14, CYA is 30 and we are brushing several times a day. Do we continue to run the pump 24/7 while doing this, or is it okay to just run it like normal for this time of year?
We had mustard algae when we started the SLAM process 4 days ago, but it appears that has all been killed. Not having much chlorine loss overnight, if any. We just still have several areas of black algae.

Once you are done with the SLAM Process, you maintain an elevated FC while scrubbing the black algae often. Can take weeks of elevated FC to eliminate the black algae.

Thank you for the reply. Do we need to run our pump 24/7 or just let it run as normal while killing the black algae?

Not sure on the pump run time, Marty can better answer that.

One trick that I used when I got some black algae this summer was to try to pour some LC directly on the spots (after scrubbing them). The more aggressive you get with Black algae the better.

Run the pump as normal.
