Salt Chlorine Generators And Cold Weather
When to open your swimming pool in Toledo Ohio is always a difficult decision as spring can be so unpredictable. Personally, I would always error on the side of opening too early. Although it may seem like a waste of money to run your pump and add chemicals to a pool you are not swimming in, the cost and headaches associated with clearing up a pool that has "gone green" can cost you a lot more in the long run.
One thing to remember if you are planning to open early and you have a salt / electrolytic chlorine generator (ECG) is that ECG's will not operate if the water temperature is below roughly 60º F. I say roughly 60ºF because each manufacture and cell varies.
Also important to note, is that your salt / mineral reading at the panel or ECG is less accurate when your ECG is in a low temperature state. So, flashing "No Chlorine" indicators are often accompanied by a flashing "Low Salt / Minerals" indicators.
Fortunately, your pool will generally remain clean despite the ECG not producing chlorine because bacteria is less likely to breed in your pool when the water is cold. As the temperature decreases so does the chlorine demand for your pool. A problem arises when the temperature does get warm enough in the afternoon for bacteria and algae to grow and the ECG is running intermittently due to cold weather. I will explain how to overcome this dilemma below but the point here is not to get too concerned about the flashing lights and warnings when the weather is cold and you have an ECG.
If you feel your water quality is suffering because your ECG is not functioning due to cold weather I would advise you take a water sample to Mossing Spas and More, our retail location, for a computerized water analysis. Be sure to let them know your ECG has not been working due to cold weather.
If you can't get a sample to our store and want to maintain your pool until the weather warms, follow the below steps.
- Treat your pool as a traditional chlorine pool
- Maintain a chlorine residual of 1-3ppm by adding 1 slow-dissolving chlorine tab per 5,000 gallons of water to the skimmer basket.
- Check manufactures specs for dosage
- If you have multiple skimmers divide dosage between skimmers
- If you cover your pool with a solar cover or auto cover, you may need to cut the dosage by 1/2 or 1/4.
- Check at least twice / week to maintain 1-3ppm chlorine
- Shock your pool at least once / week and after heavy swimming sessions.
- 1# Bioguard Super Soluble Chlorine / 10,000 gallons
- Broadcast in deep end with pool running
- Do not use a calcium hypochlorite use a dichlor
- If your pool has a green tint - double the dose.
- Add 1 oz. Bioguard BackUp Algaecide / 5,000 gallons once/week
Don't worry; warmer weather is around the corner. You will find your ECG will be producing chlorine soon and you will be able to sit back and relax in your salt water oasis.
