Lets face it, every pool will experience green water at one time or another. The key mission when this occurs is two fold. The foremost is how to treat the water as effectively as you can to have it clear again as quickly as possible. The 2nd item that needs attention is we should make it happen without breaking the bank. If you go down seriously to your local retailer there’s more shocks, phosphate treatments and water clarifiers than one knows what direction to go with. Not to mention the countless “novelty” chemicals which are available that may cost a supply and a knee!
When treating green swimming pool water, you can find 4 key steps that have to be addressed. Let’s dive in!
Treating green swimming pool water step #1: Circulation. Water circulation is a total must. You can add all the shock and other chemicals you need, but when water movement isn’t happening, it won’t change the look of the water. While you’re Swimming Pool Installation turning the pool around, run the equipment 24/7. For most standard residential swimming pools, this may enable about 3 full water rotations. Meaning, that most of the water could have experienced the filter about 3 times.
Treating green swimming pool water step #2: Shock treatment. Ideally, shoot for a granular shock since it has got the fastest reaction time. I’d recommend using HTH Super Shock which has at the least 65% available chlorine. The more available chlorine, the more effective (and faster) it is going to be in the pool water. It’s important to stress that certain cannot over shock a swimming pool. Depending on what green the water is, I’d recommend starting with 3-4 lbs of shock, wait 2-3 hours, then check what the water looks like. There’s you should not test the water at this time utilizing a test kit as the outcomes is going to be meaningless…regardless how much “free chlorine” it’s showing present.
Treating green swimming pool water step #3: Filtration is key. The more effective the filter is throughout this process, the faster the water’s going to have clear again. The simplest way to ensure this is happening would be to backwash/clean your filter several times a day. You can’t over-backwash your filter. If you’re utilizing a DE or sand filter, place the multi port valve in the backwash position and let it run for approximately 90 seconds or before the water is clear. This may have a bit longer depending on the duration of time passed between backwashes. When you yourself have a capsule filter, take away the dome of the filter (typically, there’s a group clamp that needs to be removed), lift the cartridge filter(s) from the filter unit and thoroughly clean it.
Treating green swimming pool water step #4: While the water begins turning clear (still might be cloudy, but blue (not green), begin administering a good water clarifier. This can speed up the process to getting clear water again. I’d recommend adding it the very first time immediately once you notice the water is blue and not green, then again about 12 hours later. During this process continue running the equipment nonstop. During this period you should also be stabilizing the pH and Total Alkalinity levels. I wouldn’t be worried about testing or adjusting free chlorine as it’s likely planning to be elevated for some days whilst the water adjusts, but it is essential to test and adjust your pH and TA levels.
