Algae Bloom??

[kpaveza]

Hello all, to start I have a 15 x 30' above ground pool with a cartridge filter.
1 1/2 weeks ago, we had a storm move through on a Saturday night. We were not home and my solar cover was not on.
It rained hard but for less than 1 hour.
Monday, the water seemed a little off slightly cloudy checked the chemicals and everything was in range.
Tuesday evening the water was really cloudy yellow/greenish. and could see some "sediment" on the bottom.
I let the filter run for 30+ hours no help. On Thursday I shocked it with about 1 1/2 gallons of liquid shock. and let the filter run for 24 hours it looked a little better.
Friday, I put about 10oz of Natures Way 5 in 1 ultra clarifier, by Sunday the pool was pretty clear with most of the "sediment" on the bottom.
PROBLEM is, when I went to vacuum the pool after a couple minutes I saw a green stream coming out of the return. I changed the filter and drained the holding tank it helped for a couple minutes but the green stream returned. It appears the sediment is smaller than the cartridge can filter or it gets dirty really fast and unable to filter.
HELP........
should I try vacuuming again after the sediment settles and hold a cheese cloth or something up to the reurn to "catch" the sediment from flowing back into the pool?

What are you testing the water with?

You need to follow the SLAM Process process to eradicate the algae.

What brand and size filter do you have? Do you have the ability to vacuum to waste?

I just use a 4 panel Natures Way test strip - it has worked for me the last 3 years without fail.
Ph - 7.4
FC 7-8 ppm
Alkalinity 80ppm
Stabilizer 90ppm

1 1/2 HP pump - Black Diamond 150 pleated cartridge filter

Well, we do not trust test strips and think they should just be thrown in the trash ... clearly they let you down this time

If you want to actually take control of the water, invest in one of the recommended test kits ... and then follow the SLAM Process process.

How do you normally add chlorine? Your CYA (if you choose to believe those numbers) is much too high. Making your shock FC level very high ... see the [FC/CYA][/FC/CYA]

Yea, I did see the chart - typically my chlorine is added by solid pucks through a floating chlorinator - I only add bleach or liquid chlorine if it needs a boost.

And those tablets are while your cya is too high. This is why we do not recommend the exclusive use of tablets without understanding the side effects

If that CYA number is correct then you should likely replace half the water and then stop using tablets.
