Where to start?

What is the reason for doing a drain and refill over a few days vs doing it all at once? Seems like the latter would be more effective as far as watter usage.

My water is almost clear now. How long after I have it clear should I keep it at shock level? I want to be sure I have the algae under control. It seems like the chlorine isn't lasting long and it is still using quite a bit. Testing using the shot glass method for now.

We also had an odd phenomenon happen here last night where droplets of water were falling out of the sky. I have seen this happen before, I think it's called "ran" or something like that.

The main reason for doing several smaller drainn/refills is to avoid any potential problem with an empty pool... heaving, cracking, etc. If you drain the pool, there is only the pressure of the ground pushing in on the walls, and no longer pressure from the water pushing back on the walls

ETA: keep it at shock levels until you have O CC, then let it drift back down to 8 or so, if you keep the high CYA

Lets talk him into being our "BIG PLASTIC SHEET" Guinea Pig....


Ya know you want to try it Steve

[Steve #1]

BIG PLASTIC SHEET? I'm guessing I need a big plastic sheet.... then what do I do with it?

[Phillbo]

You really don't want to know ... You may be crazy enough to do it.


The theory is that if you cover your pool with a big plastic tarp and start pumping the water out from the bottom while at the same time, filling with new water on top, You can purge all the old water without risk of cracks...

Now that's just crazy....... but jumbo trashbags filled up and tied off should work right?

OMG - when I heard the plastic sheet idea - I actually thought someone had done it. I was wondering how you would be able to pull the plastic out from under all that water - or if you went underwater and cut it in half or something.

Are you saying no one has pulled it off?

[Phillbo]

I'm thinking you should give it a shot.. It's the best way to prevent cracking of the plaster...

Like a giant bucket of water balloons!!!

And remind me how I get this measurement again.

BTW: My first thought was water balloons, I just scaled it up to trash bags.

I can't find wide enough sheets of plastic.... I'm still liking the trash bag idea.
