So I've read a bit on here and it looks like high CSI is good for new plaster (like, +0.5), through some studies that have been done. Obviously my PB doesn't read any of that scientific Darn and just does what they've done for decades, so I'm planning on mostly ignoring him because they're just gonna blame me for any plaster problems anyway, regardless of if I follow their instructions, which don't have startup values anyway, just general values (which I can get to a high CSI with and still follow their guidelines).
So I'm currently on day 2 (or maybe 1) (fill started two days ago and finished yesterday, I dunno how to count exactly).
Last night I did acid and calcium after my readings, aiming for 7.6 pH and 250 CH.
Readings this morning:
TA: 70
pH: 8.2+ (it's off the scale)
CH: 250
So my plan is to add acid to get to 7.6 since it goes up so fast anyway, and slowly add CH until I can get my CSI up towards +0.5?
Does this make sense? But to reach a CSI of +0.5, I need a LOT of CH, like 800 CH if the pH is 7.8, TA is 70, and temp is 70 (it's 68 or so right now).
And my instructions say brush once a day, I want the smoothest finish possible, is twice a day better or worse or unnecessary? I see lots of stuff between 1x to 4x a day for the first week, and then it varies after that. Why can't they just get together and actually get this right? You know they have scientists at these plaster companies who can figure all of this out precisely and give good instructions. Why is the pool industry so screwed up? (sorry, ranting)
