When to add Calcium to new pool?

[tradewinds]

Please look at my logs.

I'm around 3-days short of Day 30 on a new plaster pebble pool. PoolMath is calling for 19 lbs of calcium. Is this the right time to add and bring that level up? I believe on startup this was to be kept low to aid in removing the plaster cream?

Turn on CSI tracking in PoolMath.

CH of 200 is at the low end of OK. 300-350 would probably be better to keep your CSI up with colder water in the winter.

What is the CH of your fill water?

Fill water CH is 110.

So do I add it now or wait. CSI is 0.26

Your manufacturer should have provided you with their requirements for the first month. They hold your warranty, so go to that guide first.

Also- remember that PoolMath doesn't KNOW your pool is new and that the plaster is curing. So take it with a grain of salt when it recommends something this first month. Ask us before adding stuff if unsure.

Keep your pH in the 7s. What is your CSI with a pH of 7.6 to 7.8?

Round up your CYA to 40.

Manufacture didn't provide anything other than to say brush often which I've done twice a day after initial water fill.

You need to take your FC up to balance with your CYA level-

That was the confusing part. I added what PoolMath suggested which was about 3-1/2 cups LC (bleach) but that didn't seem it would raise the FC to match the 40 CYA, and it is also suggesting my target CYA to be 70 and to add 4 lbs stabilizer (I put 2.93 lbs in a couple of socks so far). So maybe I'm not set up in the app correctly?

 

[tradewinds]

Seems I had app set to SWG instead of bleach (have not hooked up SWG as yet). When changing it to bleach the CYA target is now 60.

 

[ajw22]

You are reading the app wrong.

CYA target range is 30-60. 40 is fine for liquid chlorine.

Get your FC up to the middle of the FC target range and don’t worry about your CYA right now.

Lower your pH into the 7’s.

 

[tradewinds]

OK, so take out the socks of CYA I put in last night and store it in a seal container or it has to throw away? I assume when I put in the SWG I'll need to bump CYA again?

When do you plan to add salt and get your SWG running?

In a months time.

 

[ajw22]

Then keep your CYA as is until after you get your SWG running, not before.

 

[ajw22]

And get your FC to at least 6 today!

 

[tradewinds]

OK, so can the CYA be stored in a seal container? Also, what about the CH?

I would just dump it. I never tried to save wet CYA.

Also, what about the CH?

Focus on your FC and pH for now.

Get your SWG running.

When everything else is good then you can work on raising your CH for the winter.

Get your priorities straight.

I took out the stabilizer and put in all the chlorine I had on hand, One to 1-1/2 gal. I also added the small amount of MA the app suggested.
