Along with the right pool, chemicals and regular cleaning, good circulation is a crucial part of keeping your water clean and clear and bad circulation means your water can quickly become stagnant and start growing algae.. Luckily, all it takes for good pool circulation. Is the right return? Jet placement and some simple filter system cleaning. Check it out..

First, how does pool circulation work? It's a simple process, but each step is critical to keeping your water moving and filtered. Step. One water flows out of the pool., Your pool pump, sucks in the water from the pool through the skimmer, and that's that rectangular port with the flap door in the pool wall. Step number two is water flows through the pump and the filter.

Once the water is Sucked out of the pool by the pump it passes through your pump and into your filter., The filter, cleans the water by removing debris and contaminants. Step number three water flows back into the pool. After it passes through the filter. The water is pushed through the pool return jets..

So how do you improve pool circulation? The first key is making sure that your return jets are positioned. Properly., Your pool jets, keep the water moving and return clean water from the filter system back into your pool.. They also help distribute chemicals throughout your water, so things like chlorine doesn't just sit in one spot in your pool. For good circulation.

You'll need to direct the water flow from your pool. Return. Jets. Return.

Jets should be multi-directional, meaning you can adjust them.. If your jets aren't adjustable, it's worth purchasing new jet fittings that are., How should you aim the return jets in your pool? Well, if your pool only has one jet point, the jet toward the skimmer and downward., This will help push water from the bottom of the pool towards the surface.. If you have more than one jet point, the jets in the same direction at a 45 degree angle toward the bottom of your pool., No matter how many jets you have make sure the pool jets aren't pushing water directly at the skimmers or aiming towards the pool. Surface., The skimmer can only pick up debris if the surface of the water is calm and not moving too fast..

That's also why you want to make sure that your water level in your pool is reaching halfway up the skimmer.. Also, when your return jets are aimed at circulating the water at the bottom of your pool, you'll help mix that cooler water with warmer water towards the top, giving you a more even temperature in your pool.. Now, what if your jets are blowing bubbles or the water flow is weak? If you see a lot of bubbles coming out of your return lines or you have weak jets, you might have an air leak in your filtration system.. This usually occurs between the skimmer and the pump, and the leak could be at the unions, pump, seals or strainer lid..

Another reason your water flow might be weak, a dirty filter system. By the way, if you're looking for help taking care of your filter system and the rest of your pool check out our free Pool Care Cheat Sheet at SwimUniversity.com/CheatSheet., It's a totally free easy-to-use guide to Help you keep your pool water, clean and clear. Okay, so one of the quickest ways to improve your pool circulation is to clean your filter system.. A clean filter means your pump, can push more water through your hoses and out through your pool's return.
Lines. Start by removing any debris from the skimmer baskets and then make sure that your filter itself is clean. If you're using a sand. Filter backwash your filter.

If your reading is 10 PSI above the normal reading., If you're using a cartridge, filter check it for buildup and spray it down in between filter changes or if your filter is reading 10 PSI above normal.. Now, if you want good circulation, how long should you run your pool filter? Well, this depends on your pool's turnover. Rate.. The turnover rate is the amount of time it takes to circulate all the water in your pool through your filtration system..

Every pool should turn over its water once daily and that usually means running your filter system for at least eight hours, a day.. Now, if you're wondering, if you have the right size, pump and filter for your pool check out our other video on how long you should run your pool pump.? Finally, let's talk about dead areas.. These are spots in your pool that naturally have poor circulation like behind ladders. Above your pool steps underneath your skimmers and cracks corners and crevices., Sometimes dead areas are unavoidable, and that means manually taking care of them by brushing your pool.

So brush your pool at least once a week, especially in those dead areas, to help break up debris or Algae and get them flowing into the filter., And if you have any more questions about, pool cleaning and maintenance go check out our free Pool Care Cheat Sheet at SwimUniversity.com/CheatSheet.

    Love this! Makes so much sense! Are you in Nepean ?

    Hi! I have pool color that I want to add for a gender reveal. How can I make the added color come out of the waterfalls of my pool?

  3. Avataaar/Circle Created with python_avatars Tony Batrof says:

    why is dirt shooting out of return jet when filter first turned on? I have a sand filter with a side mounted push/pull valve. I do back wash regularly and keep the pool chemically balanced.
    Could there be broken parts inside the filter?

    Do you have a link/ recommendations for adjustable return jets nozzles? My pool only has non-adjustable return jets+ a fountain Service area Ottawa??

    Iโ€™m so confused. Literally every article/video Iโ€™ve seen says to point jet AWAY from skimmer. So, my return jet is right next to my skimmer. I only have one and I keep it pointed down and away. Should I move it the other direction?

  7. Avataaar/Circle Created with python_avatars Jodeci888 says:

    Another great video! I have a 15 by 30 oval with one return and skimmer is only about 18 in away, should I face it down towards the skimmer or down away from the skimmer?

    I have a 28 ft above ground pool. I think it's 12,000 gallons. Not that the size has much to do with my question. I just realized on my return hose, right before the fitting that connects the hose to the jet, on the outside of the pool is a valve. It appears to be an air valve. It has a cap on it. If you move the cap just a little it allows air to mix with the return water and bubbles come out the jet.

    So the air doesn't go through the system. What is that for? And is it helpful or harmful to use? I've tried to find out but everything that comes up online refers to fixing an air leak. This isn't an air leak, it's designed to allow air in right before its shot into the jet.

    My return jets keep returning green water after shocking and now everytime I vaccinated dirt the filter brings it back into the pool

  15. Avataaar/Circle Created with python_avatars Chito's World says:

    Do you have videos for 900 gallon pools ?

  16. Avataaar/Circle Created with python_avatars Billy Boy says:

    Question: I noticed some air bubbles coming out of my returns (small bubbles, like fizz in a coke). After investigating, I found that when I turn the valve on the suction side of the pump to draw 100% from the main drains (not the skimmer), the pump sucks air (as seen thru the pump lid). I called the guy who installed the pool and he said that when air goes into the pump at a 90 degree angle at high speed, the water (H2O) gives off some of its oxygen, thus creating air bubbles in the pump lid. Does this sound right or is he blowing smoke?

    I have a question, I have a round above ground pool and Iโ€™m not getting good circulation in the center of the pool. I have the return jet pointed downwards but itโ€™s still not circulating the center of the pool. Everything is flowing properly not sure if I need to position the return jets at a different angle Service area Orleans??

  23. Avataaar/Circle Created with python_avatars D'Z RIDEZ says:

    Just opened my pool today and after putting everything back together, when I turn on the motor, water is not being sucked in and my filter is not getting any pressure. I took off the lid made sure everything was good, place it back on, and clamped the filter shut. Turned on the motor once again but nothing. ๐Ÿ™
