Taking care of own pool

Postby new2pool » Tue 26 Apr, 2011 17:11

We no longer have a pool service and are trying to take care of our own pool. We have the following issues and need some good direction. Sporadic green algae on walls that is able to be brushed off. Test strips read Free chlorine less than 0.5, pH high and alkalinity high. What do we add first. I hear some say shock the pool, or balance alkalinity before pH. We have access to all pool chemicals but just need some direction. Thanks!!!!! :)

Add chlorinating liquid or 6% unscented bleach to raise the Free Chlorine (FC) level to kill the algae. However, you should get yourself a good test kit and if your Cyanuric Acid (CYA) level is high, then dilute the water (partial drain/refill) to lower it; otherwise the algae may come back. Basically, in a manually dosed pool, the FC level needs to be at least 7.5% of the CYA level to prevent algae growth without the need for supplemental algicides or phosphate removers.

Run a Phosphate test. Too much leaves, or fertilizer may have gotten into the pool. I had the same problem and same chemical readings. Take a sample to your pool supply and ask for phosphate level.

Well, new2pool if your taking care of pool yourself then you must vacuum and clean it regularly. So that the chemicals can be prevented daily. You will get lots of pool vacuums. Also checks filter every time.
