Do I need to SLAM??

[shawnra]

I just opened the pool and am not sure if I should SLAM. It has been open for a few weeks now, and water is very clear, but there a small spots here and there where green algae is starting to grow on the bottom. I have been brushing it and vacuuming and it seems to move around a little. I have been maintaining FC around 4-7. (pH is 7.8, TA is 70, CYA is 50-60). I thought about doing the overnight test for FC...I tested about 5 pm and got a reading of 7. pump and swg shut down around 8 pm and I tested again just now (pump and swg have not yet started for the day) and got a reading of around 5.5.

So would SLAMing help here, or should I just continue keeping levels in range and chasing the little bits of algae? I attached some pics, but it is barely visible in them. It really is a small amount, but I've not had this before and am a bit annoyed with it.

Thanks!

Yes SLAM whenever you get algae. Keep the pump running 24/7 and raise your FC to slam level. It should go quick.

Sorry I missed the ph. Add acid and bring it down for the slam.

Your slam level is 24

I would SLAM it if it were mine. It may be pretty easy with this one, but I'd want to get it eliminated.

My pool is nearly crystal clear but still a bit cloudy and I just got done slamming after a very cloudy pool but didn't wait until crystal clear. The pressure is only 4% over clean and was wondering if I should be doing anything else. Vinyl liner pool. 21500 gallons.

You just need to re start, and follow your SLAM through to the very end. Make sure that all criteria are met for completion, no short cuts.

Can you leave an auto cover on while slamming this way the sun doesn't affect the chlorine?
