Moss and Algae Treatment Coverage Calculator
Calculate how much moss and algae treatment product you need based on your surface area, infestation severity, and product dilution rate.
Surface Length (ft)
Surface Width (ft)
Infestation Severity
Light (thin patches, <25% coverage) Moderate (25–60% coverage) Heavy (>60% coverage, thick growth)
Product Dilution Rate (oz concentrate per gallon of water)
Product Coverage Rate (sq ft per gallon of mixed solution)
Number of Surfaces / Coats
Calculate
function mosCalc() { var length = parseFloat(document.getElementById('mos-length').value); var width = parseFloat(document.getElementById('mos-width').value); var severity = parseFloat(document.getElementById('mos-severity').value); var dilution = parseFloat(document.getElementById('mos-dilution').value); var coverage = parseFloat(document.getElementById('mos-coverage').value); var surfaces = parseFloat(document.getElementById('mos-surfaces').value); var resultDiv = document.getElementById('mos-result');

// --- Core Calculations --- // Total surface area (sq ft) var totalArea = length * width * surfaces;
// Effective area after severity multiplier (accounts for extra product needed for heavy growth) var effectiveArea = totalArea * severity;
// Gallons of mixed solution required var gallonsMixed = effectiveArea / coverage;

// Convert oz concentrate to quarts and gallons for convenience var quartsConcentrate = ozConcentrate / 32; var gallonsConcentrate = ozConcentrate / 128;

#### Formulas Used
1. Total Surface Area (sq ft) Total Area = Length × Width × Number of Surfaces
2. Effective Treatment Area (sq ft) Effective Area = Total Area × Severity Multiplier • Light infestation: × 1.0 • Moderate infestation: × 1.5 • Heavy infestation: × 2.0
3. Mixed Solution Required (gallons) Gallons Mixed = Effective Area ÷ Coverage Rate (sq ft / gal)
4. Concentrate Required (fl oz) Oz Concentrate = Gallons Mixed × Dilution Rate (oz / gal)
5. Water Required (gallons) Water = Gallons Mixed − (Oz Concentrate ÷ 128)
