To drain or not to drain pool with high CYA?

[stevemac213]

Ha ha....exactly. I'm not sure how accurate it is because I feel that the reading would change every time I did it, mainly because I'm so new to it.

I am definitely doing bleach...trichlor and dichlor is what got me into this mess.

I was thinking about 75% as well, which is what I thought I did the first time I did this, (about 3 months ago), but I guess it wasn't enough.

Thanks.

Ben, can you pls tell me if I will need to Slam it when I refill it or do I just add chlorine/bleach?
Thanks.

Add 1 - 2 gallons of bleach every evening, till full. If you detect the slightest bit of 'green' while filling, add 4 gallons. Begin running your pump and filter, as soon as you can prime the pump, but not till the bottom of the pool is covered in water. (You don't want a jet of water hitting the pool surface directly -- depending in your water, doing so can result in stains and/or erosion.)

Likewise, avoid having fresh fill water come into direct contact with the pool surface. If there's any reason to suspect metals (iron?) are present in the fill water, add a liquid stain / scale treatment as you fill -- do NOT over dose. Dose for the water present; not for the what will be present when the pool is full.

Ok thanks Ben. Do you mean add 1-2 gallons every evening while filling it up? Not sure how long it'll take to fill but I imagine it'll be a lot quicker than emptying, since I'll have 3 hoses going in....so may take only 1 or 2 nights.

Prime the pump....hmmm. Does that mean when the water gets above the skimmer level? Also, do I need to clean the filter and if so, when?

Sorry for dumb questions but I'm a newbee.

Thanks again.

Yep, bleach every evening.

If you're new to pools, just start the pump when the pool's full . . . but if you've never started the pump from empty pipes before, you might see if someone can show you.

Ok, what about cleaning the filter....should that be done now, or after it's filled...or not at all?

Thanks.

[PoolDoc]

What type of filter do you have?

[stevemac213]

It is a Purex Triton Cartridge Filter CC320P. I cleaned it a few months ago...the cartridges were black.

Question...I put all my info in when I signed up but not sure where it went...any idea?

Thanks.

[PoolDoc]

You should clean your cartridges -- how-to here: Cleaning-your-Cartridge-Filter-without-Damaging-It!

No idea about the data.

Ok, cleaned the cartridges and let them soak in TSP overnight. They look good and got rid of lots of green...will I need to do this again after I fill it up and run the pump, due to algae that was in the pool?

Have drained more than 3/4 and have noticed some black spots on the bottom and near the stairs...looks like black algae? Thinking about draining it all.
