Estimated pool volume
17,280 gal
Volume is the anchor for every other estimate. If your pool has benches, shelves, or sharp depth transitions, size doses conservatively.
Pool Calculator
Conservative homeowner pool-dose estimates with clear guardrails
Avenblu sizes chlorine and alkalinity adjustments directly from pool volume, and keeps pH and shock guidance intentionally conservative where chemistry depends on more than one input.
Avenblu
Pool care made simple means practical guidance, clearer language, and enough restraint to tell you when it is time to verify a label or call a professional.

Advanced chemistry
Stabilizer-aware chlorine estimate
33 fl oz
Approximate 10% liquid chlorine needed to reach target free chlorine. No CYA reading was entered, so this uses a simple maintenance target. CDC's higher stabilizer minimum applies when CYA is present. Circulate, retest, and avoid stacking another dose immediately.
Dry acid starting dose
35 oz
Conservative dry-acid starting dose for clearly high pH. Circulate, retest after the label wait time, and never add more acid before the next reading supports it.
Baking soda guidance
5.2 lb
Approximate baking soda dose to raise total alkalinity. Add in portions and retest because target TA depends on sanitizer style, surface, and the rest of the water balance.
Shock starting dose
188 fl oz
Starting dose of 10% liquid chlorine for the selected condition. Planning target FC is 10 ppm.
Balance index
Advanced
Add calcium hardness in Advanced chemistry to estimate a homeowner LSI-style saturation balance.
Technician PDF
Turn the current calculator result into a clean Avenblu PDF with inputs, results, technician handoff notes, and the pool details already saved on this account.
This PDF will include the current calculator result only. Sign in and save a pool profile if you want account-level pool details included.
The PDF is informational and technician-friendly. It does not replace fresh water testing or product-label directions.
Assumptions and guardrails
Liquid chlorine and shock estimates use the product strength entered in Advanced chemistry.
pH outputs are intentionally limited to conservative starting doses when pH is clearly high or low.
Stabilizer-aware FC targets are industry planning estimates, not CDC mandates or permission to swim at high chlorine levels.
The balance index is an LSI-style estimate for sequencing, not a full lab water analysis.
Do not add chlorine and acid together. Circulate the pool, then retest before repeating any correction.
Calculator outputs are informational starting points for homeowners, not manufacturer instructions or a substitute for full water testing. Always verify the product label, circulate the water, and re-test before repeating an adjustment. Escalate severe algae, equipment issues, stains, or unsafe conditions to a qualified pool professional.

Community invitation
Ask one useful question, or start with a simple introduction
Avenblu grows the community through real pool-care questions and firsthand answers. The best way to make it more useful is to post a real question, join the weekly check-in, or introduce your pool setup with a few honest details.
Weekly topic
Share what your water looks like this week
Clear water, cloudy drift, algae recovery, or a chemistry question that still feels unresolved all belong in the weekly check-in thread.
Open the weekly threadStarter checklist
Post details that make the next answer better
- Know the pool type and rough gallons or dimensions.
- Share chlorine, pH, and alkalinity if you have them.
- Describe the issue and what changed recently.
- List what you already tried before asking for another dose.

Chlorine basics
Understand why sunlight, swimmer load, pH, and debris change how fast sanitizer disappears.
Next step
pH and alkalinity

Turn the dose into a follow-up schedule so one correction does not become three guesses.
