Pool Cleaning

How do I know if my pool filter needs to be replaced versus just cleaned?

Replace cartridge filters every 2-3 years, sand filters every 5-7 years, and DE (diatomaceous earth) grids every 7-10 years under normal conditions. However, if regular backwashing or cleaning no longer restores proper pressure readings or water clarity, or if you notice physical damage like tears in cartridge pleats, cracked grids, or channeling in sand, immediate […]

What causes black algae and how is it different from regular algae?

Black algae forms protective layers that penetrate pool surfaces, requiring aggressive brushing with a steel brush, high-dose chlorine, and algaecide. Less common in New Jersey pools than green algae but more difficult to eliminate once established, black algae can survive normal sanitization levels and persist throughout the swimming season if not properly treated. Understanding Black

Can I use my pool vacuum if the water is still cloudy?

Yes, you can use your pool vacuum when water is cloudy, and in many cases you should—vacuuming removes settled debris that contributes to cloudiness. However, if your pool is extremely cloudy or has visible sediment on the bottom, vacuum directly to waste rather than through your filter to avoid clogging the filtration system. After vacuuming,

How do I get rid of mustard algae in my pool?

Mustard algae requires aggressive treatment to eliminate completely from your pool. Brush all pool surfaces thoroughly, shock the water with triple the normal chlorine dose (30-40 ppm), run your filter continuously for 24-48 hours, and sanitize all pool toys, floats, and cleaning equipment that may harbor spores. This yellow-green algae is particularly stubborn in New

How do I fix a leaking pool and where do leaks commonly occur?

Common leak points include skimmer connections, return fittings, pool lights, main drains, and liner seams in vinyl pools. To confirm a leak versus normal evaporation, perform a bucket test by comparing water loss in your pool to water loss in a bucket placed on the pool steps. Once confirmed, inspect visible fittings and equipment—freeze-thaw damage

What’s the difference between stabilized and unstabilized chlorine?

Stabilized chlorine contains cyanuric acid (CYA), which acts as a sunscreen to protect chlorine from UV degradation in outdoor pools, while unstabilized chlorine lacks this protection and is ideal for indoor pools, spas, and shock treatments. For New Jersey pool owners dealing with intense summer sun and humid conditions, maintaining stabilizer levels between 30-50 ppm

Should I cover my pool during the summer when not in use?

A solar cover reduces evaporation, retains heat, and keeps debris out—especially helpful during New Jersey’s frequent summer thunderstorms. It can save you money on water, chemicals, and heating costs throughout the swimming season. However, you’ll want to remove it periodically to prevent excessive moisture buildup underneath and allow proper air circulation. The decision depends on

Why does my salt water chlorinator keep showing a “check salt” error?

Your salt water chlorinator’s “check salt” error typically indicates one of three issues: salt concentration outside the optimal 3000-3400 ppm range, dirty or scaled cell plates preventing accurate readings, or water temperatures below 60°F which temporarily disable chlorine production. In New Jersey’s variable climate, cold spring water during pool opening season is often the culprit

What’s the ideal chlorine level for my residential pool?

Maintain 1-3 ppm for standard chlorine pools and 2-4 ppm during peak summer use or after storms. Test 2-3 times weekly during NJ’s swimming season when heat and humidity accelerate chlorine depletion. Your specific target depends on pool type, bather load, and seasonal conditions common to northern New Jersey’s climate. Understanding Chlorine Levels for New

Why is my pool water cloudy even though the chlorine level is correct?

Cloudy pool water despite correct chlorine levels typically points to filtration problems, poor water circulation, high total dissolved solids (TDS), or imbalanced pH and alkalinity. In New Jersey’s hard water regions—particularly across Morris, Essex, and Somerset Counties—elevated calcium hardness frequently contributes to persistent cloudiness that chlorine alone cannot resolve. The issue often stems from inadequate
