about to give up!

When was the last time the filter was disassembled to clean it?
What is the filter's clean pressure & what pressure do you backwash at?

Last time it was cleaned (I think) was when it was opened two weeks ago. Clean pressure is 10 and dirty is 30-40 - the dial says clean and dirty.

 

[Mike1162]

Is there good flow from the returns when the pressure is over 30?
I'd clean it tomorrow & filter through the skimmer.

Ok, so I think from pasting it all together our plan will be:

1) add DE (already done, will be wasted per plan below)
2) vac to waste
3) top off water
4) filter on recirculate
5) shock tonight per pool math
6) vac to waste again tomorrow or sunday (how will we know it's time?)
7)clean filter tomorrow
8) go back to filter once murky blue

pls confirm that is the plan thank you!

If you're vacuuming to waste and running on recirculate, there will be no water going through the filter. So the filter won't need cleaning tomorrow.

 

[andyjames]

but I think the filter is dirty and per mike1162 he said to clean it?

when vacuuming to waste, will my filter waste water go through the backwash hose or is there another hose that needs connnecting? There is no other opening.

 

[Mike1162]

He's been filtering very green water for two weeks. I'm betting the filter needs cleaning but will rephrase. I'd clean the filter tomorrow if the pressure while filtering was 15 or higher.

pool math problem?

Pool math said 7 bottles 121 oz bleach to get us to SLAM (16 FC) and 10 min after putting the bleach in we were at 4. What is wrong? pump on recirculate.

Re: pool math problem?

Ammonia perhaps. Follow the ammonia removal protocol. Keep adding bleach to 10 ppm and recheck every 10 minutes until it holds FC above 5. After that bring CYA to 30 and then SLAM.

 

[andyjames]

Re: pool math problem?

here are our pre-shock stats:

FC 0
CC 0
CYA 40
TA 100

Still ammonia?

 

[kellyfair]

If I’m not mistaken, it would be weird if you could maintain that CYA with ammonia in the water. Your overnight drop is most likely because there’s a lot of stuff in that water to fight! But, you can certainly check... add FC to 10 while circulating, check a few minutes later. If your FC is above 5, ammonia isn’t an issue, you just have a lot of stuff to kill.

When was the CYA added?

 

[andyjames]

so we are on day 4:

FC 16
CC 1

holds overnight, goes down to 15 and we top it off with a gallon of bleach

still green! clear in shallow end cloudy in deep but green

pump on circulate

help? 4 days is normal?

CYA was added few weeks ago

 

[Mike1162]

I'd start running the filter.

 

[andyjames]

Regarding the filter, we cleaned it and it was a complete mess - only two weeks the pool had been open. So now it's sparkling clean but there is boat loads of live algae still in the pool. Marty had said keep filter off until it gets murky blue and we aren't there yet.

This morning, day 5 of really consistant SLAM not letting it drop more than 1-2 FC, we are at 13 and I'm adding 1.3 bottles bleach to get it back to 16.

Day five? Help, it's not changing!

 

[mknauss]

At this point your pool should no longer be green from algae.

Do you know of any metals issues?

Try going to filter and see what occurs. If your FC is holding as you say at SLAM level you should not have large amounts of live algae.

I agree with said advice.

You've been brushing the pool? Are you brushing the walls too? If you start filtering, you should be able to see the bottom better and perhaps there may be some organic debris that is contributing to the murkiness.

If your CYA is 40, your shock level is 16.

Yes, you can have ammonia and still have some CYA left. Just did a pool that had 12ppm of ammonia and 40ppm of CYA.
