What would you like to do?
If you are adjusting pH, add acid by spreading it around the pool with filter pump ON. Leave pump run for a couple of hours after adding acid. If you attempting to adjust Alkalinity, add acid by pouring into one spot in the deep end, with filter pump OFF. Leave pump OFF overnight. I disagree with the statement above. The pump should remain running in all instances. If your pump is scheduled to shut down in less than an hour then wait till the next day where you can add the acid earlier in the day. With the last 2 sentences - that is probably the worst possible answer. Acid poured in a "column" ( one spot) will find it's way to the main drain grate and settle there at the grate and in the sump until the pump starts the next day. Thus sucking all that acid solution directly into the system and the heater - the worse place it could possibly be. The acid may dissapate some in the overnight hours but it may not all get diluted.

Assuming you live in an area where pools are winterized and shut down for winter, I would run filter for 45min - 1 hour per day. Be carefulk not to over sanitize the pool …because chlorine (etc) demand is very low while water is so cold. If you expect to experience freezing weather then do not turn your pump off. LEAVE YOUR PUMP ON. Moving water can not freeze. As water freezes there is expansion. This freezing/expansion can destroy your pump, filter and pipes. Steve Dunn Commercial Pool Systems, Inc.
Answer Absoltutely not. The pressure underground will lift and crack your pool. You should lower the water to below the skimmers and do a full pool closi…ng for the pipe system. If you don't know how to get the water out of the pipes and filter you must call a professional. Most owners do it themselves but be sure to learn the proper technique.
Answer It is best to leave running. Have a neighbor check for anything unusual.
nearly 45 minutes
I have a spa that overflows into the swimming pool and a solar system heating the pool. When the pool pump turns off most of the water drains from the spa why is this and is there a way to stop it.?
Answer yes, you could install a check valve on the line that feed the spa with water. it depends if that line has been buried or not how hard the job will be.
It can be added right away as long as you add it at the opposite end of where you added the acid.
You can use it straight away it mixes very rapidly and if you swim in it it will mix even more quickly.
You are scheduled to winterize the pool next week but wont use the pool from now on so can you turn off the pool pump now to save on running costs?
Sure you can turn off the pool pump, the water won't be circulating anymore but since you are not using the pool it does not matter. Make sure the outside temperature is… above freezing until winterizing because non moving water freezes earlier than moving water. Here is my blog on how I handle my pool: http: //live-efficient-green.blogspot.com/2009/07/pool-with-no-harmfull-chemicals.html
If the pool is properly grounded and bonded, with ground fault interupt circuit, it is safe. I would not run if a thunder storm is approaching. Of course, they should not be i…n the pool during a thunderstorm at any rate.
Keep on running it.
If your salt chlorinator works by way of water passing over or through an electrolytic cell then it should automatically shut down once the water flow is ceased. The reason fo…r this in-built safety is a by-product of chlorine production is hydrogen gas and if the cell is left to operate with no flow the gas will build up within the pipe work and one spark will set it off. Years ago there were convection chlorinators that were installed during the construction of the pool shell. These operated at a very low voltage all the time with the result of constantly making chlorine with the convection current drawing water from a hole at the bottom and chlorine gas and water exiting a hole above. Hydrogen gas simply exited through a vented cap on the coping.
Muriatic acid is most commonly used in swimming pools to lower the swimming pools PH and to lower the pools alkalinity. You should use caution when working with muriatic aci…d. Not only can it stain your clothes, pool deck, etc, but if you inhale too much it can cause tissue damage. Always consult a professional when working with chemicals that you are not completely knowledgeable about, some swimming pool chemicals when mixed wrong can have a chemical reaction and catch on fire.
At least 5 hours .If you don't think its ready,wait 2 more hours.
Because the pressure tank is "waterlogged" . This means the necessary air has evacuated from the pressure tank and it is now full of water. It should have about 28 psi of air… in it. You will need to re-pressurise it. This tank where the water enters from the pump is a critical part of your system . It should have an 'air charge' of approximately 27-28 psi if the pressure switch is a standard 30/50 switch. If this air charge has gone down, then your water pressure will be lower. If this tank is very old, possibly silver or green in color, then it's a "galvanised tank" and is possibly 'waterlogged'. This means you have to recharge the air with a compressor (just like blowing up an auto tire) To do this, switch off the pump. Open a faucet near the tank and let most of the water out. When you think it's nearly empty, close the valve to house and pump in with the compressor till the needle on your tank gauge points to 27, 28 psi. Now switch on the pump and the pressure should be improved. -IF your tank is a pale blue one, then chances are it's a 'bladder' tank and low pressure means your bladder is leaking. -You can pump it just as I said already, but in this case it will only last 2-3 months. You basically need a new tank. In all cases check the size of the pressure switch. It's printed somewhere on it . 30/50 as I've mentioned is common but some are 40/60. In this case pump in 38 psi of air. Both pressure switches are adjustable to a small degree by turning the central spring up or down. It's essential that lower limit of this switch is 2-3 psi above residual air pressure . Always use a good round tire pressure gauge, (available in auto stores for about $5.) to check tank air pressure, Don't rely on the installed gauge, they soon get erratic.
I think you have that option after you join-not before.
