Question

[rmyoung]

First time to get algae in pool .it isn't bad mainly in deep end and on ledges. I followed the instruction
On this site and got my FC up to 12 and checked it 4 times starting at 4 pm.each hour had FC loss of about 3-4. When I went to bed my FC was 12 and now this morning is a 12. Does this mean I am ok I can still see some green but maybe I didn't brush good enough.dont know if it matter but no sun today it looks like.

If you still see algae, then you fail the clear water criteria to stop the SLAM. Keep SLAMing and brushing.

Agree with Jason. Brush the pool n SLAM.

Brush, brush, brush.....

The algae may have a biofilm over it and brushing will berak it up allowing the chlorine to do its thing.

Ditto.. keep the faith

You need to maintain the FC as best you can until you no longer see any sign of algae and your water test shows a CC of less than .5 and you pass the OCLT. If you were testing ever hour and losing 3-4 it doesn't make sense you went to bed and it suddenly stabilized. Just saying that doesn't sound right as the FC will drop a little less each time it's tested and adjusted back up. Going from dropping 3-4 in an hour to not dropping at all overnight just doesn't sound possible.

You have only mastered one of the three steps necessary to insure it doesn't come back. Follow the directions for the SLAM and you'll have sparkling clear water in no time.

What test kit do you have ??

How do you chlorinate your pool?
What is your CYA level?

 

[rmyoung]

I use bleach and my cya is 30. I am getting frustrated because I brush 3 times a day but I still have areas that won't go away. Today I only lost 2 ppm over 6 hours but still can't get it gone.

Do you have poor water circulation in the areas with the visible algae? Can you post some pictures of the problem areas?

 

[rmyoung]

I will post pic in morning. I have waterfall on different pump near area would running that help

I would like to give you a positive answer, but all I can say is maybe. It is not beyond the realm of posibility that the are I question does not circulate well without the additional pump. This would end up being an area With lower FC leading to algae. Not saying that is the case, but possible.

 

[rmyoung]

It could be because it the deepest part of the pool but it is closest to equipment.If it is poor circulation what do you do. Also turned n water fall which is about 5 ft from problem area

If your brushing and it's not coming off have you checked for metals? Try dropping a vitamin C pill on the stain to see if it lights it up. Probably a good idea to post a complet set of test results.
