Yep, that's a perfect use for dichlor...adding FC and CYA to fresh fills.

If you can pull from just the main drain, that should work fine. I've emptied my entire pool that way!

I doubt that's the cause of the pitting. I have some missing pebbles in various places on mine too, I think it's just part of life.

My CH out of the tap is lower (200-250ish) but I just let it rise until it hits about 1000, which takes about 3 years. Then, it's full drain and refill. I know some people capture the water from the rain gutters on their roof; that's a great idea if you have them.

It shouldn't matter when you put it in. I think using chlorine gas would be correct.

Another vote for borates...I can let my CH run all the way up to about 1000 before having problems.

The bucket test would be a good idea. How are you testing? Pool store tests are notoriously unreliable...we strongly recommend doing your testing yourself with a good drop-based kit. Unless you have a leak or a gigantic amount of splash-out, CH will never go down, only up. It stays in the...

That's correct...just keep adding acid to bring the pH into the acceptable range, and the TA will gradually come down along with it.

Odd that it seems stuck at 7.8...very common to see it stuck at 8. Anyway, you'll probably make your life easier just by doing the drain and refill like you said. Rather than renting a pump, I'd would either: - buy a pump (since you'll be using it every 2-3 years), or, - do a little bit of...

Nope, it doesn't go bad. Your pH probably started much higher (off the scale) and...is still likely off the scale. If you keep adding acid, it will come down.

I just look to see.which popups are up, then dump a bunch there. It mixes very quickly so I don't worry about trickling it.

I wouldn't worry about it...just don't leave it out there all the time!

I've had my pool for 4 years now, and it was a fresh fill when I bought the place in Sep 2009. I drained and refilled in spring of 2012 since the CH had gone from ~250 up to about 1000. I figure it'll be an every 2 or 3 years thing. The less CH your fill water has, the longer you'll be able...

No, it won't. They're unrelated, and you can deal with them later!

Welcome to TFP! Did you use any algaecide? That can cause foaming...but even if you didn't, a swamp cleanup often does funny things all by itself. Keep at it!

130 isn't high...you can definitely get that low and keep it low. I don't know what Mark's is, but mine comes out around 220 and eventually settles around 80.

Is it really at the surface? that would mean your whole yard is seeping water, and if you dig a 1-inch deep hole, it will fill. Is that really the case?

Re: New to forum - new test kit - results are in - please he 2 or 3 feet should be OK. Once the pool is full again and has circulated for an hour or so, retest and see where you are.

Sounds like you're not missing anything, it typically is that easy. If your system is happy with the salt level there's no need to match any specific number. Increasing CYA gradually is a good idea...you don't say how high you want to go, but I'd say 70 or 80. Your system will work harder to...

Nope, not from the rock. Your CH is high because your pool water evaporates and is refilled. So, one pool-full of water = 170 CH. Over a year or two, all that water evaporates and is replaced with new water...the CH does not evaporate, it stays. Now, you have 340 CH, 170 from the first fill...

Welcome to TFP! If you keep on top of the pH and TA levels, never letting them get too high, then you can run it successfully with the CH up there. If you're careful enough, and use borates, then you probably won't get much scaling in the cell either. I let mine go past 1000 and it worked...

Toss the blue box for the little taylor kit...at least that's how I got mine in!

Sounds like you've had a bit of algae? First thing to do is be sure it's gone...have you run the overnight chlorine loss test? That will tell you if you still need to be shocking. As for the CH, there's nothing you can do but manage it. Play with the pH, TA, and CH numbers in the pool...

It sure looks like something pooled there, especially in that last picture. You can see two little pools, one on each step. Any idea what could have sat there, before the pool was filled?

yep...baking soda will increase the TA with a minimal effect on the pH.

Do you have a squeeze-to-spray type hose nozzle? I bet if you put that on there and pointed it straight down, it would work even better!

Re: Funniest/ most ridiculous thing the pool store has told Using cal-hypo will eat the pebbles out of your pebble-tec. :scratch:

Something isn't adding up here. Ih Phoenix with CH of less than 10, that water has GOT to be softened. No way around that one. Is that the same water you used to fill the pool? What did the CH start out at? Another possibility - are you sure the tablets you're using are trichlor and not...

Sounds like the water at your tap and the water filling your pool aren't the same. Do you have a water softener or undersink RO unit? Try getting a water sample from your outdoor fixtures. High CH is just a fact of life in our area. I've had my pool for 3 years now and watched the CH climb...

I've always thought that chlorine will break down the reagents...I await the actual truth!
