To answer your question - yes, recheck CYA levels (during daylight). With a sand filter, backwashing will reduce CYA levels.
Thanks, Abigail. I'll do that this afternoon.
Test #25:
SLAM: 16 ppm FC
FC: 19 ppm
CC: 0.5 ppm

Even though it's not clear, the water still looks better than it has in years!!
Good. It is time. Let us know what you see/find.I will do a deep-clean of the sand filter tomorrow, but I don't know what else that I can do
I think I'm going to give it another week and then let the FC level drift down so that the girls can swim.
Good. It is time. Let us know what you see/find.
The girls (or anyone) can swim NOW if the FC is below normal SLAM level and the water is clear enough so that you can see anyone on the bottom.
You can take the pool to SLAM level first thing in the morning. With sun, FC will drop below SLAM level fast, let anyone swim, then resume SLAM in the evening. As long as you get at least two SLAMs in daily, it (the SLAM process) will work - only slower since folks will be swimming and the SLAMs are fewer.
The more you an SLAM after the sun is off the pool, the better![]()
Just remember, it will take longer to complete the SLAM.![]()
Take a picture of the whole system as in all of the hoses/pipes leading to and from it.
Great pics! I want to really look at your set up when I am fresh LOL! That is quite a set up you have there! I have a couple of ideas.
I will get back with you tomorrow.
Got to keep going strong, you can beat the algae.
I hope the pic unloaded. It should be your second pic. looking down at everything.
I see the black valve thing that if I am seeing it right goes to the return. Does it close so that water cannot come/go?
See the long, black pipe coming from the pump to the filter? I am thinking it comes from your skimmer. Is there any way to stop water from coming/going from it?
Do you have a shop vac?
I will wait for you answers before I go to my ideas. I am trying to save you a mess of water and get you set up so it will easy in the future to service your equipment.
Wow! I am impressed with this thread and time line. Your tenacity at trying to beat this problem is nothing short of inspirational.
Being a thin-blooded south westerner, we get warmer weather and a lot more pool season than you all north of the border. So I totally understand your burning desire to get that water crystal clear.
Excellent post with lots of great pics. Should be required reading in pool school.
Best of luck to you![]()
Again, GREAT pics! okay words to know-------black flippy thingy and Jandy valve. Got it and love it! Girl talk at its finest!
So what I am seeing is that there is no way to to stop/block the water from/to the pump/skimmer. How do you open your pump basket to clean it without flooding?
Okay here goes----------see that long black pipe that goes from the pump to the filter? I would put a union like this on it.
Once you have blocked the water with valves (black flipping and Jandy) you should be able to disconnect all of the hoses/pipes going to the filter.
Now this is where I get a little stuck BUT you should be able to do a search on your filter make/model to see how to take the top off.
Now this is where I have another idea or two for cleaning your sand. With your filter being in the garage you will not want to do what I do----------just stick a hose in it and let it go! Water and gunk up and over!
I am thinking of one or two things-------wheelbarrow and large, clean garbage can. IF you shop vac rolls good just vac up as much sand as you can and roll it out to the garbage can. Have the girls help you get the sand from the vac to the can. While you are getting more sand out of the filter have the girls rinse the sand in the can. If your vac does not roll good you can put it in the wheelbarrow.
I hope this makes sense to you.
