Sand filters use chlorine because the sand is added for filtration, but chlorine sanitizes the swimming pool water. Sand, cartridges, and DE can't replace chlorine because they have different purposes. However, you can use swimming pool robots, salt systems, and other tools to improve your pool water.
So if you've ever wondered if it's OK to put chlorine tablets in the skimmer, the answer is yes. As your pool pump runs, water floats in through your skimmer line, past the pump, into the filter, through the heater, and back into the pool.
Never put chlorine tablets into the skimmer baskets of your pool. Some pool companies will put chlorine tablets directly into the skimmer baskets of the pool. Never allow anyone to put chlorine tablets in these skimmer baskets.
A better method is adding chlorine tablets directly to your swimming pool skimmer. When your filter is running, water will move quickly over the tablets in the skimmer basket, dissolving them much more effectively than the floater does.
Some pool owners who have a sand filter choose to use biguanide sanitizer, but this tends to stop up the filter, which is why those who use this chemical needs to change the sand more often. Properly maintaining your sand pool filter is the key to extending its life and preventing the need to change the unit out early.
Another option is a floating chlorinator which is just a plastic vessel that holds tablets and floats in the pool. Floating chlorinators are super cheap and can usually be found in local stores like Walmart. Whatever you do, though, please do not put chlorine tablets into your skimmer or pump!
You simply place your chlorine tablets in the floater (based on gallons of water in your pool), and it does the work for you. The downside to a chlorine floater is that it is a passive system, so sometimes it can get stuck in one spot for a period of time.
For the greatest protection against algae, bacteria, and cloudy water, Intex pools should maintain a chlorine level of 2.0-4.0 ppm at all times. If you opted for the Intex Salt Chlorinator, you can make your own chlorine by adding the correct amount of Pool Salt to the water.
It is recommended to wait at least 20 minutes to an hour after adding water balancing chemicals. You should wait 2-4 hours (or one full cycle through the filter) to swim from the moment you use calcium chloride in your pool. It is safe to swim once your chlorine levels are around 5 ppm or after 24 hours.
Add one tablet for every 5,000 gallons of water and always round up. For example, if your pool has 21,000 gallons of water, add five tablets per week. If it has 8,000 gallons, use two tablets.
Chlorine tablets are slow dissolving and therefore need to be placed in either a floating dispenser, in-line chlorine feeder or a skimmer basket.
Chlorine Floaters: For each 5000 gallons of pool water, add one 3″ chlorine tablet. Open the baffle or vent at the bottom, fully open.
A sand filter is essentially a tank full of sand that's connected to your pool's filtration network. As pool water passes through the sand tank, the sand catches debris and particles and prevents them from returning to the pool. This results in cleaner, clearer water.
You still need the sand filter. The saltwater setup turns the salt to chloride (sodium chloride) and the ozonator kills germs etc... the sand filter filters out the algae and all the other particles before the water goes through the saltwater system.
The most important factor though is the size of the pool. You'll need about 52-104 oz of liquid chlorine per 10,000 gallons of water. This amount should get the chlorine level to between 5 and 10 ppm.
The best time of day to shock your pool is in the evening. This is because the sun's rays can affect the effectiveness of the chlorine by dissolving it too quickly, before it has a chance to rid the pool of contaminants and clean the water.
INITIAL STARTING DOSAGES :
Maintain chlorine at a minimum of 1.5 ppm and up to 3 ppm. The more swimmers you have and the warmer the water is, can double your pool's chlorine consumption. Add whatever amount of chlorine it takes to maintain a 1.5 ppm chlorine..
Answer: Yes, when using tablets they can be present in the water while you swim. Also confirm with a test of the chlorine level to be sure the sanitizer level is safe for swimming.
As a general rule, we see stabilized chlorine tablets (also called trichlor tablets) last anywhere from two to three days. Slow dissolve cal-hypo tabs may last four to five days.
Chlorine is a chemical that inhibits bacterial growth in water. It's used to disinfect swimming pools and drinking water and sanitize sewage and industrial waste. It's also an active ingredient in several cleaning products. Chlorine poisoning can occur when you touch, swallow, or inhale chlorine.
We dive in and find out. Liquid chlorine is preferred over chlorine tablets by pool professionals however home swimming pools will benefit too. Liquid chlorine quickly raises or maintains chlorine levels without raising stabilizer. Chlorine tablets maintain chlorine levels and add stabilizer to the pool water.
It's often recommended to shock your pool once a week. If you don't do it every week, you should at least do it every other week. This is necessary to maintain your pool's water chemistry.
