If your pool has been green all season you're probably super excited to close it. While it seems like the easiest option – it's not! It's much smarter to close your pool as clean as possible. Algae can grow in water as cold as 50 degrees.
Closing a pool that is green with algae, or dirty with debris or with water that is unbalanced, leads to heavy staining and saturation of the water with dead algae cells, which makes it easier for subsequent generations to grow.
Cleaning your pool before closing for the winter prevents algae and makes your spring opening even easier. Make sure to thoroughly brush the sides and floor, skim the surface and clean out the skimmer and pump baskets after vacuuming the pool.
Keep in mind that the chlorine shock will destroy the algaecide. The best course of action is to add the shock five to seven days before closing your pool, and then waiting to add the algaecide until right before you put the cover on.
September and October are a good time to close the pool because the weather is ideal. It's still warm to be outside, enjoying the sun, even if you hate to say goodbye to summer. But once those temperatures start dropping significantly, you're going to kick yourself for not closing the pool sooner.
By simply adding algaecide to your water prior to closing, you can prevent algae growth from occurring during the cold, winter months which makes for an easier opening in the spring. You can apply algaecide directly to the pool water and allow the pump to continue to circulate for approximately two to four hours.
Lower the water level to just below the mouth of the skimmer. This removes the water from the throat of the skimmer, which could easily sustain damage should water left there freeze. Also remove the water from the plumbing lines using a shop vac. Be sure to plug the empty lines to prevent them from refilling.
So while a solar cover won't actually 'turn your pool green', it will warm your water by up to 8 degrees, so if the other conditions are right, adding a solar cover can easily accelerate algae growth, very rapidly. You need to get the water balance in your pool right before putting the cover back on.
Shock the pool with chlorine every day until all the green is gone (possibly 3 to 4 days). 2. Run the filter 24 hours a day and backwash every day until the green and then cloudiness is gone (usually up to 7 days, sometimes as long as 2 weeks depending on the filter). 3.
Covering the pool is a good way to prevent algae growth. The right cover keeps algae from entering the pool, but it also keeps leaves, bugs, bacteria, and dirt from decomposing in the pool, providing algae with food.
Shocking your pool is easy: Use a shock treatment to bring your 10 to 12 PPM. Then, wait a day or two for the chlorine to come down to its normal level, about 1.5 to 3.5 PPM. Pro tip: For best results, shock your pool a few days before you plan to shut it down.
When the levels are properly balanced, chlorine will keep the algae at bay, but the water will slowly begin to turn green as the algae take over if there's not enough. But be careful—adding too much chlorine in pool water can cause those metals to oxidize and turn the pool a different shade of green.
No, you don't need to drain all of the water. We know that draining your pool is a hassle and you want to conserve as much water as possible; however, it is necessary to drain some of the water out of your pool. You will need to drain the water level down below the skimmer level.
For most folks however, I would recommend a tight fitting winter pool cover, to keep maintenance to a minimum, and to protect and secure the pool during the off-season. But it is possible to close a pool, without covering the pool, but it's best to cover the pool that is not circulating.
You may naturally assume it's best to completely drain your pool of water for the winter months, because you fear the water will freeze and cause damage. Actually, it's not good to leave your pool empty when the weather gets cold.
If you close your pool too soon, the winter protection chemicals you've added will often not last until spring. The reason is that your pool chemicals are consumed much faster in hotter temperatures versus in cooler temperatures. This can, in turn, cause algae blooms and staining in your pool.
You do not need a pool winterizing kit. Weird first sentence for this article, but it's true. You really only need one chemical (algaecide) to properly winterize a swimming pool. You need some other stuff to protect your pool from harsh winter conditions, but only one chemical to add when closing.
Green discoloration in a swimming pool is caused by the growth of algae, a type of green aquatic plant that floats on the surface of water. Algae usually flourishes in warm water but can still take over your pool in winter if given half a chance.
The water level should be about a foot below the skimmer if you have a mesh cover, and about half a foot below the skimmer for solid covers. Depending on how you're removing the water from your pool, this process may take a day or two.
Depending on the size of your pool, we still recommend you run your pump run at least 4-6 hours a day during the fall and winter months. The daily cycle can be divided into multiple cycles, but each cycle should be no shorter than 4 hours, for all the water to pass through the filter at least once.
The experts are a split on how much a pool can contribute to a home's value. One HouseLogic study suggests an increase of 7 percent, at most, under ideal conditions, while HGTV reports that the average inground pool can up your property's value by 5 to 8 percent.
