An easy way to know whether your sand filter has enough sand is to check how full the filter is and what the sand looks and feels like. The filter container should be two-thirds to three-quarters full of sand. Look for interior marks indicating the ideal sand level. If you put your hand into the sand, it should flow through your fingers without clumping. The filter pressure gauge is also an easy indicator—the right amount of sand leads to normal pressure, while too much or too little sand can cause high or low pressure.

A fiberglass pool lasts up to 30 to 50 years with proper maintenance. For the longest possible lifespan, keep your pool water pH as close to seven as possible. Test your water levels regularly, run your pool filter daily, and avoid draining the pool. Once your pool is 20 to 30 years old, you can prolong the lifespan by refinishing the shell.

Costs range from $25,000 to $50,000, depending on size, design, and additional features.

Calcium hypochlorite, or cal-hypo, tends to be the best shock for an above ground pool. It is widely available, affordable, and powerful. Cal-hypo shock is typically 65% to 75% chlorine and is very effective at ridding a pool of bacteria or other contaminants.
