Now is the time to replace your pool filter sand! Show During the cooler months is the best time to replace your filter media, you wouldn’t want summer to hit and find you are struggling to keep your water clean, all because your old filter sand is worn out. During summer many pool businesses are just too busy and you may have to wait weeks for your sand to be change. Sand in your filter should be replaced every 5 to 6 years, any longer than this you will be using more chemicals, losing water clarity and backwashing often. Your old sand becomes compacted, clumped and creates channels where water channels through unfiltered. We replace your old sand with activated glass filter media and we do this at the same price others would offer for sand! Glass is traditionally twice the price as sand but not with AquaTec Pool Service. Benefits of using activated glass over traditional sand filter media.
At AquaTec Pool Service we pride ourselves on professional service, we will take utmost care with your pool equipment, leaving no mess and no fuss. Prices for replacing old filter sand with new activated glass media: Includes all labour and glass media.
Note: prices are approximate and may differ depending on filter size, access to equipment and other factors. Pricing does not include removal of old sand. We were presented with a challenge: could Orenda products clean a heavily-loaded commercial sand filter enough to prevent a sand change? Challenge accepted. Paddock built a nice YMCA aquatic center with a vacuum sand filter eleven years ago. Today, it is home to a 300+ athlete swim team, a masters swim team, school programs for learn-to-swim and water aerobics. On any given weekend they can host swim meets of over 700 swimmers. We consider this a heavily loaded commercial pool. Fast forward to 2017. That same YMCA is in desperate need of its first sand change. Eventually, there is no getting around it; this sand is not doing the job anymore. The YMCA has been backwashing several times a week, the water has been dull and cloudy, and the sand had channeling issues. The estimated cost of the sand change: $3500. The job involves four guys laboring all day to get the sand out—either by a costly vacuum truck or shovels and buckets—then carry in the 100-pound bags of sand back in to replace it. This particular filter has thousands of pounds of sand that serves about 150,000 gallons of water. Paddock challenged us to see if our natural chemicals could refurbish the sand, and therefore extend its useful life. In theory, if our CV-600 Enzymes are strong enough, they should be able to soak into the sand bed and break down the non-living organic waste (grease, oils, bather waste of all kinds) that act as a 'glue' in the sand bed. This organic waste is what clumps sand together and makes it gross. We traveled to Rock Hill to purge the filter because we accepted the challenge. Sand filter purgeWe met with Dennis Ingram, service manager for Paddock Construction Company. He has been doing these types of sand changes for 12 years, and has done hundreds of them. Dennis remained skeptical of our theory (and for good reason). However, he was hopeful and excited too. If we could refurbish this sand back to its original condition, it would be huge for Dennis and pool service professionals like him. We used only two products for this experiment: PR-10,000 Phosphate Remover Concentrate, and CV-600 Enzymes. We added half a gallon of PR-10,000, which reacted with phosphates in the water upon contact. We then added one gallon of CV-600 enzymes, and our CEO, Harold Evans, climbed down into the filter with a rake. He raked the sand to try and mix in our products as deep into the sand bed as possible. After raking for 10 minutes or so, Harold climbed out and we let the natural chemical soak for an hour. We watched the non-living organics rise from the sand bed up to the surface and bubble. The greasy oil-slicks were being consumed by bubbles, which showed us the enzymes were hard at work. CV-600 breaks down carbon waste into CO2 and H2O. The bubbles indicated the off-gassing of CO2. It was cool to see in such a high concentration. And when we say greasy oil slicks...we mean it. Fill the tank, watch the bubbles, avoid the smellWhen we let the filter tank fill up with water, it looked like a dirty, soapy hot tub. We saw bubbles everywhere, and the entire pump room smelled like a sewage plant. It was disgusting, to say the least. That being said, we all had smiles on our faces, because it meant what we were doing was working. We filled the tank and let it sit for another hour and continue to soak and bubble. Dennis then backwashed twice, back-to-back. We noticed a few things after these backwashes.
All in all, the purge took about 3 or 4 hours including set up and clean up. We actually had enough enzymes remaining to do a full purge of the 150,000 gallon pool. So we poured the right amount into the refurbished sand filter and left the facility. The experiment was a total success. You should refurbish your sand filter. Here's why.According to a few studies like this one and this one, sand filtration removes microbial contamination and particles from water. This is great for the water itself, but it means that those diseases and other contaminants remain in the sand bed. When bacteria gets lodged in the sand bed, it is hard—if not impossible—for chlorine to kill it. If chlorine could oxidize what was in the sand filter effectively, what we did in Rock Hill would not have been necessary. Who knows? Maybe sand changes wouldn't be necessary either. It stands to reason that the vast majority of diseases and other contaminants in a pool system are in the filter itself. We believe that purging the filter with our enzymes is beneficial for the health of the water, because it allows the sand to
Challenge ConqueredThe YMCA saved thousands of dollars, and got a few more years of life out of their sand. It also saved Dennis and Paddock a full day of labor with four guys, and a tremendous amount of heavy lifting. While refurbishing sand will not permanently prevent you from needing to change your sand—friction will eventually wear down the sand itself—it can give you more time. Contact your service provider to learn more about how Orenda can refurbish your sand filter. If needed, have them read this and watch the video above. How often should the pool filter sand be changed?When do I need to replace my sand? On average, sand should be replaced every 3-5 years. This may be longer if the pool stays clear, or shorter, if the filter runs all the time. The jagged edges of the sand wear down and become smooth as the sand ages.
What is the life expectancy of a pool sand filter?Sand filters will often be able to perform for around three-to-seven years, depending on use. If you frequently clean and backwash your filter and only use the pool seasonally, you can expect to replace it after at least five years.
How do I know if my sand filter is bad?If your swimming pool begins to seem a bit cloudy or unclear, then you may have a sand filter that's running slowly. This can happen even though your sand filter looks fine and seems to be running as it should. It can look like how it's supposed to but not be filtering debris from your pool as it should.
