    How to add salt

    I have some questions about starting my SWG. I'm coming up on a month since my pool was filled. From what I hear, one must wait a month before starting up the SWG.

    My PB is taking care of the chemicals for the first month but after that I'm on my own. I bought the SWG generator myself so I don't think the PB will be adding any salt.

    Where is the cheapest place to buy salt? I see Home Depot has water softener salt granules for fairly cheap. The bag says something like 'up to 99.6% pure'. This kind of bothers me. I would prefer to see something that says at least 99.6% pure. What kind of salt does everyone else use? I assume the pellets would be much more difficult to disolve.

    How do I add the salt? Should I pre-disolve it a bit at a time in a bucket or can I just sprinkle it around the pool? Should I pour it into a skimmer or main drain?

    Thanks

    Re: How to add salt

    The water softener salt @ HD or Lowe's works just fine. I think it's called solar salt. The stuff I bought was in blue bags, best I can remember. I figured up how many bags I needed, and poured them in around the edge of the pool, then used my brush to stir it up quite a bit.

    I found this thread in the "Automatic Chlorinators:SWG, Liquidator, etc" forum.

    I dump it in the deep end brush to the main drains. It doesn't take along time to dissolve. This is what I used from Lowes.

    Re: How to add salt

    I bought Morton's pool salt from Sam's Wholesale. I think it was $4-5.00 for a 40 lb bag. I didn't wait a month to start up my SWG. Did it week one, poured it in, brushed it around and made my kids play with it until it dissolved. (I know, I'm a terrible mom.) No problems. My pool is AG so maybe that makes a difference as to why I didn't have to wait a week.

    I always recommend that you add it to the deep end of the pool and brush it around a bit until is dissolves. Remember in colder weather the salt will take a longer time to dissolve.

    You only need to wait a month to add salt if you have fresh plaster/pebble.

    Re: How to add salt

    I just pour the salt in the skimers (3) by the time I get the third filled the fist one has almost desolved. Since I need 1,200 lbs of salt I try to find the 80lb gags of solar salt in the blue bags. The last time, it cost about $7 per bag, however that store has closed, So I may need to go with HD.

    Re: How to add salt

    Thanks for the answers. It sounds like it doesn't make much difference where the salt is introduced since it disolves quickly.

    Re: How to add salt

    I want to mention that it took 12 hours for the salt concentration to level out - I poured the 560 lb salt (= 7 blue bags) into the shallow end and brushed it around for 10 minutes. Except for a few pebbles that came with it it had completely dissolved. At first the salt reading was 5700 ppm ! Shock ! But the heavier high salt water from the bottom must have migrated to the main drain, thus giving the SWG temporarily a higher concentration of salt.

    The test kit salt test strips and the SWG measurement of the salt concentration agreed on salt levels.

    pauster,

    Are you pretty sure that your pool is 25K gallons? Mine is really close to 25K by meter reading. If so, mine should also take about 560 pounds.

    Re: How to add salt

    Hi Kevin,

    that's what the pool builder told me but I have no way of being certain. I bet they did not know for sure either, hard to tell with a free form pool.

    According to the Pool Calculator http://www.poolcalculator.com/ it would have taken me 669 lbs to get to that level so either I have less water (closer to 21000 gal) or already had some salt in the water (not impossible).

    I only used 7 of the 8 80 lbs bags I had and I am glad I did.

    I suggest you sneak up on the right level - put in 6-7 bags, measure, check with your SWG manual for the optimum level and then continue to add gradually.

    Re: How to add salt

    You definitely had some salt in the water already. Practically every pool chemical adds salt along with what ever else it is doing and there is usually at least a little salt in the fill water.

    Re: How to add salt

    I would think so - the AquaPure told me 143 (ppm) but I don't know how accurate the reading is at that level ... I guess the safest way is to take your time and test ...

    BTW I had only added 3 or 4 gallons of bleach, some dry acid and CYA, the water is fresh from the tap (70%) and a truck (30%) ...

    Re: How to add salt

    Is there any difference between the Morton Pool Salt (white bag) and the Solar/Water Softener Salt? Is one better then the other?

    Re: How to add salt

    Yes like anything with pool in its name cost! Also the solar salt has bigger junks, but that is not a problem; just takes a little longer to disolve.
