Visalia 25k Gallon Filling Now
Visalia 25k Gallon Filling Now
I'm in the process of filling a pool that has been empty for a few years. I'm looking for some help in getting the water balanced. Here's the particulars.
Location: Visalia, CA
Weather: Very hot and dry, >95 deg most days.
Type: In-ground, concrete/plaster.
Size: About 25k gallons (will measure more accurately soon)
Filter: Sta-Rite PLM150
Controller: Intermatic P1353ME Multipurpose Control timer
Filter Pump: Pentair two speed (HP 1.0/.12)
Booster Pump: 3/4 horse Franklin Electric 778 (for Polaris)
Water Source: City supplied tap
It has been filling over night and is close to half full now. Here's the current readings using a Wal-Mart HTH 6-way test kit...
CL: 5ppm
PH: 8
CH: <40
TA: <30
The chlorine is from me putting in about 1/2 gallon of 8% Soduim Hypochlorite last night before I went to bed.
Assume for now that the pool is 25k gallons. Whatever numbers are appropriate for that I will moderate down somewhat and ease into it.
Here's what I think I'll be wanting to purchase today...
-Baking Soda to raise TA without raising PH
-Calcium Chloride to raise calcium hardness
-Muriatic Acid to lower PH
-Cyanuric Acid
-Calcium Hypochlorite or Dichlor or Trichlor for chlorination since I also need calcium and CYA
1) What's your best guess on the quantities I'll need of the chemicals listed above?
2) Do I need more calcium than what I can practically add via chlorinating with Calcium Hypochlorite?
3) Do I need more cyanuric acid than I can practically add via chlorinating with Dichlor or Trichlor?
4) Should I hold off on lowering PH via Muriatic Acid until I have the CH and TA up to normal levels? I figure my current Saturation Index is (assuming 76 degree water) about -0.5.
I guess that's about it. I've got another 12 hours at least before it'll be full enough to start the filter. You guys buoyed my sanity back years ago when I first built a pool, and I thank you from the bottom of my heart. I'm looking forward to another dose of your sage advice again.
