Need Algae removal advice

[George Whitzel]

I had green algae and used the SLAM method. The water is now blue and there is remains of dead algae at bottom of pool. How to I remove it and get the water clear again?


Current pool readings are
FC 5
CH 350
CYA 60
TA 100

If you still have visible algae, the SLAM is not complete. It’s a process, not a one and done thing.

Have a look at this:

So even though the pool has turned from Green to blue it still has live algae in it?

If you read the SLAM article you need to keep the level of FC at SLAM level until the process is complete.

This includes removing all signs of algae dead or alive. Algae can also still be an issue even in a clear pool.

Maintain the SLAM level
FC until the water is crystal clear. Otherwise the algae may dominance again. Brush and vacuum. Skimmer socks or hairnet in your skimmer basket may help you get some of the dead algae out before it hits the filter. Clearing the last phase of cloudy blue with white dead algae takes a little time with a sand filter.

I think I have turned the corner on the algae removal as I can now see the bottom of the pool again. I will continue SLAMing and brushing until I see the pool is crystal clear. Thanks for everyone's help and advice.

No, please read the directions on SLAMing your pool in the How To section of Pool School and follow that procedure completely to the end.

That is:

- CC is 0.5 or lower;

- You pass an OCLT (ie overnight FC loss test shows a loss of 1.0 ppm or less);

- The water is clear. (including no visible algae)

When all three are true, you are done SLAMing and can allow the FC to drift down to normal levels.

What test kit are you using?
