Sitting Pool Water

by Paula

Above-ground pool installed and electrical contractor bailed before the work was finished. Water is to full level.

We're scrambling to get another contractor, but the best so far is that it will be up to 2 weeks.

What we should do until then?

Thanks for the question Paula

Sorry to hear about your situation. In my experience, if you don't have the filter running and the chemicals properly balanced, chances are your pool might turn green with algae.

When a pool sits without any circulation and the water/weather is warm, algae is almost a certainty. This is not the end of the world, it just means that you're probably gong to need to shock the pool and go through the steps to clear it up.

You can dilute chlorine and broadcast it around the perimeter of the pool and sweep the best you can to mix it up. This will lessen or delay the effects of the algae bloom.

But again, without filtration and circulation you're going to have algae.

If it's a fresh fill, you don't have any stabilizer in the pool. You can use Dichlor to get some stabilizer in there, then switch to regular chlorine.

I wouldn't suggest using too much chlorine because you have a vinyl liner. Chlorine is heavier than water and will sink to the bottom. If it's not swept or the water circulating, you run the risk of bleaching the liner.

If it was my pool, I'd let it go until the filter is up and running, then clear the pool up.

Pool Pump Is Down
by: Anonymous

I really need some reassuring. Pumps down for 4 months now since Aug 10th. Insurance took 2 months to tell me it was the circuit boards that need replacement which they now do not cover!

Now that we know problem, money is tight. Can the pool surface be damaged with all the algae? It is dark green and heavy at bottom of pool. I've tried scooping out. Heavy and dissolves when out of water. lots of debris as well. My husband says no big deal. Other people say I'm going to damage the pool if I don't fix soon! I plan on fixing either end of December or January.

I'm just afraid pool will be damaged if I wait any longer. I even thought about not paying one month rent to fix pool to prevent further damage to surface. It is of concrete surface (dark like lagoon style). System is on a EXP control panel. So has to be running in order to drain and refill or do anything to it.

Thank you!

Thanks for the question

It's hard to say if the pool will be "damaged", which is very subjective. Obviously one of the worst things that can happen is the pool can be stained with algae, but this can be treated using an acid wash, if needed. Normal shocking procedure is needed to get rid of the algae.

Many people who winterize their pools will have a mess during Spring opening, but this is expected. Their pools are not damaged and they close and open them year after year with little to no problems.

I would ask what kind of damage your friends were referring to when they talked to you about the pool?

I know it probably looks like you'll never clear it up but I can tell your from personal experience that I've cleared up many green swamps on my pool route in Arizona. Some did require an acid wash, but I always took them on a case-by-case basis.

The main thing is to remember that you probably won't get the water clear overnight. It may take a few weeks of scooping, filtering, brushing, backwashing, and shocking.

Shocking is a process, not an event. The trick is to get AND keep the chlorine above 10 - 12ppm for a period of time.

If you would like personal assistance, I do phone consultations for a donation of your choice. It makes things go much faster. If you choose to not go that route, we can correspond by email.
