We're getting new plaster tomorrow, Stonescapes Micro, and will do the bicarb startup. Fill water calcium is very low, CH=60, and I'll be adding 100lbs of sodium bicarb into the fill barrel. How much should I put in the barrel at one time? There will be 1-2 other hoses filling the pool so whatever comes out of the barrel will immediately be diluted. I thought maybe put in 50 lbs, fill half the pool, then put in 50 more, but wonder if I should divide it further. Thanks. Pool is about 24k gallons.

What is your TA?
maximum combined TA and CH can be limited to a total of "400 ppm" but is also okay to go as high as 500 ppm
Get the bicarb in the water and let it mix in the pool. You don't need to split it up into many batches.

It is an unfortunate fact that most tap water used to fill swimming pools is often soft, aggressive, and somewhat harmful to a new plaster surface. Therefore, in order to not damage a new plaster surface, the tap water needs to be “balanced” (meaning for new plaster, the CSI should be at least...

TA is 70 but CH is 60. The dosage equations yield values ranging from 90-124 pounds of sodium bicarb, depending on whether you use the 400 or 500 target. So I got two 50 lb bags to use. Just didn't know if I should put it all the barrel at once. Thanks.

Are you certain that your pool is 24,000 gallons? The gallons of a pool are often over-estimated.
Is the plasterer letting the pool sit for a day and giving the plaster a water rinse to exposed the aggregate?

If you add calcium, do not add it at the same time as adding bicarb because they will combine into a hard mass of scale.
I will double check the estimated volume using the usual dimensional formula. With pool empty I did discover it's 8 ft deep instead of 9 that I was told by previous owner.
He is planning to trowel the cream off and not do acid rinse. WE did not discuss rinsing it with water. I'm filling so will wait 4 hours after plasterers finish. Should I get them to rinse with water?
I prefer that no water rinsing be performed.
For the accurate volume, make sure you subtract the step areas and curved walls.

Thanks. Finer measurements with pool empty yielded 3168 cubic feet, or 23700 gallons. Was pretty close. When filled I'll measure at the meter. Bad news is the tile was laid wrong, resulting in having to replace about half of it and the local store has no more. Warehouse deliver will take several days so we're going to be on hold until the middle of next week.
Sounds like a good plan for checking the water volume.
Glad to see that the plaster guy will remove the plaster cream and not water rinse the surface.
Sorry about the tile problem and delay.
