    opening pool

    I have been reading a bunch of posts about how to open my pool as well as reading pool school. I wish I had a better understanding of all of this. I was starting to get the hang of it but winter clogs my mind....
    Anyway should I turn on my pool and let it run for 24 hours before I even test my water? I ended up with a hole in my cover after a big storm. I can see the bottom of the pool and it has thin layer of debris covering entire bottom. Should I allow the filter to start working before I test levels or should I test them before I turn on the pool? not sure where to begin.
    Thanks for advice.

    Re: opening pool

    It can't hurt to stir the water some before testing, but if it was mine I would add a preventitive dose of liquid chlorine/bleach as soon as the cover comes up, it is cheap insurance angainst having an algae bloom in.

    Okay, I poured in 6 96 oz bottles of 6% bleach. It ran overnight and I have murky blue water. I still have the cheap test kit but will be buying a good one this year. I am going to let pool store test my water just to get an idea of where I stand. Does a pool usually need more than just bleach when you are opening it?

    Re: opening pool

    Not being too hard on you, but since you have 70 posts I'm gonna be a little hard. The very first things you should have done was to run the pump for an hour THEN tested the water (or let the PS test it). The first thing you should have looked at was the pH. It needs handling before any shocking starts because the pH test isn't accurate at high FC levels.

    Also adding 19ppm FC to your pool isn't a good thing without knowing what your CYA level is. 19 ppm might be fine but then again it might not be.

    Now that I have that out of the way. Take a sample to the pool store and post the results here.

    You said you have a cheap test kit so I'll assume you have an OTO chlorine test (yellow drops). If you do take it and test the chlorine. If it's within the 0-3 or 0-5 range test the pH and post the numbers here. We will help you get the pool in good shape.

    Re: opening pool

    I deserved that......I just read so much conflicting stuff. I will take a sample to the pool store tomorrow and post results. Pool is blue this morning just can't see the bottom. Once the results are posted I am sure you guys will tell my what I need to do the cheapest way possible. Thank you.

    Re: opening pool

    My Ph is 7.2 it needs to be between 7.5 and 7.8 correct? I am still using wal mart tester but will buy good one this season.

    Re: opening pool

    If the PH is around 7.2 and you are not using trichlor tablets, then you can leave the PH alone and it will tend to come up on it's own over time. If you are using trichlor tablets, or the PH appears to be going down from there, you should bring it up.

    You did good!

    As Jason said, Leave it alone for now but keep an eye on it. Post those PS results as soon as you get them.

    Re: opening pool

    I am afraid to do nothing at all today, don't want to lose any momentum. If my Ph is 7.2 should I add any more bleach on top of what I already put in yesterday?

    Re: opening pool

    PH and chlorine have very little to do with each other.

    To give you specific advice it would help tremendously if you posted a full set of water test results and described how the water looks today.

    Re: opening pool

    Last night after running filter for a few hours and putting in bleach I tested the water with my wal mart tester becasue its all I have as of now. so as of last night around 7pm, This is from memory so bare with me

    Ph 7.2
    TC 5 + (doesn't read any higher) after I added 6 bottles of bleach.......
    I did the dilluted test that I learned on here last year and it was around 5ish........

    I have no clue as of yet what my CYA level is. I will take water to pool store tomorrow but I know that is not accurate at all. I just have to do the best I can until I get a good test kit.

    Re: opening pool

    As long as the water is clear, the PH is between 7.2 and 7.8, and you don't have any better information to go on, just raise the TC level back up to around 5 each evening and you should be alright.

    Work on getting better information, you should buy a top quality test kit and get some pool store results while waiting for it to arrive. There are very likely other things that need to be done, but you shouldn't risk doing anything else without more information.

    Re: first set of numbers

    It depends on what you are going to use for chlorine. If you are planning to use bleach or a SWG then in 15,000 gallons I would add 5 lbs of stabilizer, to target a level of 40, to start with. Then give it a week, test the level, and adjust from there.

    Langelier index is a method of estimating the risk to plaster pool surfaces. Not only is it not important for an above ground pool, but they appear to have calculated it wrong. In any case ignore it.

    Re: first set of numbers

    okay so I bought four pounds of stabilizer do I put it all in at once and buy more? and do I add bleach right after or before?? Do I take it to shock level?

    Re: opening pool

    Yes, add all four pounds "at once" just very slowly. You can either pour it into the skimmer very very slowly, or put it in a sock or stocking and hang the sock in front of a return. If you add it to the skimmer you need to not backwash for a week.

    As long as the water is clear, just at 4.5 ppm of chlorine. You can add chlorine and CYA in either order.
