Estimated pool volume
17,280 gal
Volume is the anchor for every other estimate. If your pool has unusual benches, sun shelves, or depth transitions, adjust conservatively.
Pool Calculator
Beginner-friendly chemistry guidance with the formula logic separated from the interface
The Avenblu calculator is intentionally modular, phrased as guidance, and ready for expert-reviewed refinement in future passes.
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.
Pool size
Sanitizer guidance
pH guidance
Alkalinity
Shock estimate
Liquid chlorine guidance
332 fl oz
Approximate 10% liquid chlorine needed to reach your target. Re-test after circulation instead of stacking another dose immediately.
Dry acid guidance
31 oz
pH demand depends heavily on alkalinity and product strength. This is a homeowner estimate, not a chemical guarantee.
Baking soda guidance
4.8 lb
Use this to raise total alkalinity gradually. Smaller follow-up doses with re-testing are safer than one big correction.
Shock estimate
1,880 fl oz
Shock targets vary with CYA, product type, and water condition. Treat this as a first-pass estimate and confirm label instructions.
Calculator outputs are informational estimates for homeowners. Always verify product instructions, circulate the water, and re-test before repeating an adjustment. Severe pool issues should be escalated to a qualified professional.
