How to Measure Pool Depth
Pool depth is measured vertically from the surface of the water straight down to the pool floor at that point — not from the top of the coping or deck, and not the wall height…

Green Pool Water That’s Not Algae
Pool water that’s green but stays clear rather than cloudy, and that gets visibly darker right after a shock treatment instead of clearing, points to dissolved metal — usually iron or copper — oxidizing, not…

How to Get Dirt Out of a Pool
Heavier dirt responds to vacuuming to waste or a robotic cleaner with its own onboard filtration, but very fine silt or dust is often too small for a standard sand filter to catch and needs…

How Often to Change Sand in a Pool Filter
Standard silica sand filter media needs replacing roughly every 3 to 5 years, sooner if you notice cloudy water despite balanced chemistry, backwash cycles needed more often than before, or pressure that climbs faster than…

What Speed Should You Run Your Pool Pump?
Low-to-medium speed, run for a longer daily cycle, is the efficient standard for routine pool filtration — pump energy use scales roughly with the cube of speed, so cutting speed in half can cut power…

Best Sand for a Pool Filter
Pool-specific filter sand, commonly labeled #20 silica sand at a 0.45 to 0.55mm effective size, is the correct media for a sand filter — generic play sand or mason sand is the wrong grain size…

How to Fix Acidic Soil
Agricultural lime is the standard fix for acidic soil, raising pH by neutralizing excess acidity, though the exact rate depends on how acidic the soil is and its texture — clay needs meaningfully more lime…

How to Get Rid of Bindis in a Lawn
A selective, grass-safe herbicide matched to your specific turf type, applied in late winter to early spring before bindi flowers and sets its sharp seed heads, is the standard fix — a non-selective product like…

How to Acid Wash a Pool
Acid washing a pool removes a thin layer of plaster along with the staining embedded in it, using a diluted muriatic acid solution applied to a drained surface, scrubbed, and neutralized immediately — it’s a…

How to Increase Soil Microbial Activity
Feeding soil microbes with organic matter, keeping soil aerated rather than compacted, and maintaining steady moisture without waterlogging are the three levers that actually increase microbial activity — most synthetic fertilizers don’t add microbes at…

How to Get Rid of Scum on Top of a Pool
Floating scum on a pool’s surface is usually oils — sunscreen, lotion, and body oil residue — combined with dust and pollen collecting at the waterline due to surface tension, and it clears with skimming,…

How to Quiet a Noisy Pool Pump
A pool pump that’s suddenly noisier than usual is almost always one of three things: cavitation from restricted water flow, a worn motor bearing, or vibration being transmitted through the equipment pad — and each…
