Getting your pool in balance post-Harvey

Cleaning and draining your pool (if necessary) is a big part of getting your pool back in shape after heavy rains. But just because your pool is glistening does not mean that its recovery from Hurricane Harvey is complete. For your pool to truly be in tip-top shape the water chemistry must be in balance.

In this article, we’re going to take that newly cleaned pool water and make sure it’s chemically in balance. If it isn’t, we’re going to show you the importance of that balance and how to achieve it.

Putting your pool water in balance

The pool in the picture above looks glistening and ready to go, but having clean, aqua pool water doesn’t necessarily mean that everything is up to snuff. There are three areas of water chemistry which are extremely important in the well-being of your pool — the amount of cynaric acid, the calcium content and the alkalinity.

It’s very important to continuously check these metrics and not simply stop and be satisfied once the water is a desirable color. If you don’t check them, especially when dealing with a rain and flooding event such as Harvey, you leave your pool susceptible to algae blooms and scaling.

We detailed these measurements in an article we did on IntelliChem. While the IntelliChem system will let you know what the measurements are, the cynaric acid and chlorine will have to be applied separately.

Of the three measurements, cynaric acid might be the most important. Cynaric acid acts as a stabilizer, protecting the chlorine from getting burned off by the sun and losing its potency. Cynaric acid operates in a similar way that sulfates do in wine or homogenization does with milk. It keeps the chlorine fresh so it can do its part to get your water in balance. Having 30-35 parts per million of cynaric acid will help chlorine do its thing and help with calcium and alkalinity.

If you simply shock the pool every so often or throw in chlorine tablets without paying attention to the cynaric acid output, you’re likely to get the dreaded algae and scaling. And that’s not a good time.

How calcium and alkalinity keep water in balance

Keeping tabs on calcium is extremely important, as too little calcium will cause the water to eat away at the plaster while too much calcium will cause scaling on walls and on the pool surface. You want to keep the calcium between 200 and 400 parts per million, with 250 being the sweet spot.

As far as alkalinity, keeping it under control is necessary to prevent corrosion of the metal equipment in the pool and staining of the plaster. The range for alkaline substances is 80 parts per million to 200 parts per million, with 120 being the ideal amount. You should also aim to have the pH in your pool between 7.2 and 7.8, with 7.5 the prime target. Chlorine, with cynaric acid as a lead blocker, can get these elements to where you need them to be. For best results, have your free chlorine at 3.0 parts per million. As always, feel free to contact us with any questions about these matters.

Cleaning and draining your pool post-Harvey

Now that Hurricane Harvey’s rain has fallen, it comes time to assess the damage and clean up your pool. There are several factors to consider when cleaning or draining your pool, between your safety, particulates in the pool and rebalancing the chemistry of the water. We did a short “what to watch for” post last year during the torrential spring rains that Southeast Texas was getting. That’s a good reference while evaluating what you need to do.

The above picture shows one of our pools in the aftermath of Harvey. The owners were lucky not to have much in the way of flood damage, and their IntelliChem system did its job in helping keep the pool’s chemistry on point throughout the storm. We offer the IntelliChem system with all of our pools, and having one — and putting it to use — drastically reduces the need for draining your pool.

Cleaning and draining your pool: What to look for beforehand

Unfortunately, Harvey wasn’t as kind to all of our customers in Montgomery County and Southeast Texas. Some of them fell victim to the flooding that plagued (and still plagues) the region. That resulted in pictures such as the two below.

In the cleaning your pool article that was linked in the first paragraph, there were three things that needed to be monitored: safety from fallen items/animals that might have drifted in the pool area, particulates such as dirt/mulch and leaves, and water chemistry. Since Harvey was much more a rain event than a wind event in Montgomery County, falling debris from trees and houses weren’t as much of a concern. However, insects, reptiles and small mammals could have been washed into your pool area (depending on how much flooding you received) and the sheer amount of rain water will throw your chemistry off.

But a big X-factor in the Harvey clean-up will be keeping mindful of possible bacteria. The Association of Pool & Spa Professionals warns that animals and possible sewage in flood waters can cause spikes in E-Coli and other harmful bacteria. It advises using bacteria test strips on the water to get readings. If there is a bacteria issue, chlorine might not be effective, so use products such as Sea Klear PRS Stage 1 and 2 to break down the bacteria and trap it in your filters.

Draining your pool: Do’s and dont’s

We covered the process of this last year, which we paired with the other linked article in the first paragraph. Please feel free to read this, but we’ll also highlight a few things that might be relevant for this storm.

One of the main things you need to do is clean your filters constantly. The filters serve as an integral part of the cleaning process, as they trap the debris and separate it from the pool water. However, when you’re dealing with floods and rain water of this degree, the filters will get full, overwhelmed and not do their job fully if left unmonitored. Therefore, it’s important to clean and empty them yourself or call us to do it for you for a fee. Cleaning and emptying filters are available for a fee as part of our pool maintenance services.

Along with keeping the filters in tip-top working shape, you also need to brush your pool several times a day. Brushing the pool uproots debris that’s clinging the surface of your pool and releases it into the water. From there, the filters and vacuums can capture and separate it. Brushing the pool also is huge in preventing algae from forming down the road. It also allows the IntelliChem system to balance the water chemistry more effectively.

As far as dont’s, do not ever drain the pool completely. If you do that, the shell of the pool will “pop up” and “float” out of place, causing an extreme headache and even more labor. The saturation of the ground after a rain event like Harvey makes a dislodged shell even more of a concern, as the moisture and dirt below the surface push the shell out if there’s not enough volume inside the pool to push back against it. It’s a phenomenon we detail in this article.

Instead, drain the pool no more than halfway and refill the drained portion with clean water. From there, use vacuums and filtration to further clean the water, along with the IntelliChem system’s water chemistry capabilities. Sometimes one draining will do the trick; sometimes you’ll need more. Either way, never drain the pool more than halfway. This is another service we provide for a fee as part of our pool maintenance package.

Either way, your pool will once again look like this.
