    Deck fountain piping algae

    So we recently purchased this house with a pool and there is a PVC pipe directed straight up uncovered towards the sky. Took a look today and it was filled with standing water and green algae. I took some extra PVC pipe and made an attachment so it wouldn't blow into the pool and with pump running I opened the valve isolating it. I blew it out for 10 seconds then shut valve, soaked up some water then poured in a dose of CL. And covered pipe. Should I shock the pool and refill that piping with the new water after shocking or should the CL I added do the trick? It's the longest piping length as its furthest from pump.

    I'd just run the fountain for a while and keep an eye on your chlorine, and run it for a while every day to prevent future growth. The algae will only grow near the opening because it needs sunlight.

    I'd just open the valve a little bit so water is always circulating through it.

    There's nothing hooked up to it currently. I poured in some bleach and capped it off with a PVC cap.

    The bleach and cap should stop it from happening for a long time. Algae needs sunlight to grow and the cap solved that and it'll keep the bleach from getting degraded by the sun.
