    Newbie with Test Results

    I just bought a house with a pool last week and I'm trying to get up to speed on maintaining a healthy pool. I bought a TF-100 test kit and listed my results below. If anyone could tell me where I should start I would appreciate it.

    FC- 1.5
    CC- .5
    Calcium- 225
    TA- 90
    CYA- 0

    Thanks!

    Welcome!

    pH is critical - that's the parameter that dries skin and irritates eyes. Don't forget to test it. If it's off, adjust that first. Your FC is actually okay for zero CYA. How does the pool look? That's the important thing. If the water is hazy or cloudy or green, nobody cares what the numbers are - they won't want to get in.

    If you really, truly have zero CYA, you need to get some in the water or whatever chlorine you add will be broken down by the sun within hours. If there's any question at all that you did the test correctly, watch the videos.

    Re: Newbie with Test Results

    Sorry, I thought I did post that stuff in my signature. I'm not sure why it didn't show up.

    My PH level was right around 7.8 or possibly a little higher. I looked at the videos for the CYA test. It looks like I did it right. I filled up the entire tube, but could still see the black dot. It did start to get a little hazy at the top, so I guess there's a little bit in there.

    I'm not sure if my minds playing tricks on me, but the pool is starting to look a little green. When we got the house the pool had a little bit of mustard algae in it. They treated it with an algal divide. I've seen a little bit form on the steps. He thought it was because the skimmer needed to be cleaned out.

    What would you recommend I do? Stabilizer first? Shock?

    Both. But adjust pH first. You need to run the Shock Level And Maintain process if you're seeing green. For your CYA level, chlorine shock level is 10 FC. So use poolmath to calculate that and add it right away. Then add enough stabilizer to get you up to 30 CYA via the sock method. From that point, target 12 FC. Do not neglect to brush, and see if you can't figure out how to get behind your light and scrub the niche. Algae likes to hide places like that. Also under ladder rungs. The light typically has a screw you loosen and then the whole thing tilts and lifts out and the cord lets you set the thing up on the deck.

    Re: Newbie with Test Results

    Thanks for the reply! I went into Poolmath. It said I should add 23 oz of Mutriatic Acid. Once I add that how long should I wait to retest the PH? I assume that once I get the PH between 7.2-7.5 I should raise the FC. Once I'm ready to raise the FC should I add stabilizer at the same time, or should I wait? Sorry for all the questions.

    Re: Newbie with Test Results

    Wait 30 minutes to retest the pH. Once pH is where you want it raise the FC.

    Yes, raise the FC and add CYA via sock method at the same time. It will take a while for the CYA to dissolve.

    Re: Newbie with Test Results

    Thank you! The kit is great! So I got my PH down to about 7.6. I added bleach and the stabilizer around 2 PM. I just got home from work to check the chlorine levels and they're now:

    FC- 2
    CC- 4

    Does it make sense that my CC's jumped up? Was that from the stabilizer? So now according to the instructions on the site I'm supposed to try to keep my FC at 10 ppm...right? So I guess I should add and check every hour or two? How long should I do this for?

    Yes, it does. That means the chlorine is reacting with something. It probably smells like a public pool right now, too. CC will go up and down erratically during the SLAM, don't try to detect a pattern to it.

    Assume the CYA is dissolved (even if some is still in the sock), so shock level is now 12 FC. Just keep replenishing it to keep it at 12. Don't neglect to brush. It helps mix the bleach and scrapes the slimy scab-like film off the algae so you can kill it.

    Well, as long as you can until the FC starts to hold and the CC drops. Naturally, you can go to bed after the last test/add/test tonight and start again in the morning!

    Continue until you pass the three criteria that determine you are done with the SLAM process. See red lines in my sig.

    If you cannot babysit the pool, test/add in the morning to SLAM level and start again when you get home. Folks that can babysit the pool and stick with it without interrupting the process can finish sooner. But, everyone cannot do that.

    Re: Newbie with Test Results

    I just ran out and tested again about 2 hours after I added another 222 oz of bleach. My readings said FC- 2.5 CC- 2.5. Is that normal when you're shocking your pool? I thought I would get really high FC readings after adding that much bleach. Somewhere closer to 7 or 8? Also, I'm supposed to keep shocking the pool...right? For example: When I got the readings that FC was at 2.5, I went to poolmath, put in my FC numbers at 2.5/12 and it said to add 270 ounces. Sorry if this is a dumb question. I just want to make sure I'm doing this right. I've dumped like 7 jugs of bleach in my pool today.

    You've just got a hungry green monster in there. Keep at it. Testing and dosing as often as you can. You'll get there.

    Yes, it's normal. You have something in your water that the chlorine is killing so it's using it up quickly.

    It may help if you don't think of "shocking" your pool as a one time thing. You are now SLAMming your pool and a SLAM is an ongoing process until you clear the 3 criteria to end the SLAM. It may only take a day or two or it may take a few weeks. You can read more about SLAM here READ ME! Test, dose, brush, and an hour later test, dose, and brush again.

    You did... they just didn't stay high for very long...

    ... so you need to keep testing frequently & adding more chlorine to raise it above shock level each time.

    Re: Newbie with Test Results

    Is it safe to get in the pool while I'm Slamming it? There's some spots I need to get in the pool to get with a toothbrush. Mostly it's in the holes on the side and around the light. Also, the stabilizer is in the skimmer via "Sock Method". Is it safe to get in while that's in there as well? I noticed the pool is looking brighter. I tested it twice this morning. The last time I check FC- 2.5 and CC- 1.0. I also check to see how the stabilizer was doing in the skimmer. It looks like it's about gone. There's a little bit left, but not much.

    Yes, you can go in at normal shock levels. The CYA in the skimmer is not a problem.

    Re: Newbie with Test Results

    Ok, so I pulled the light and sure enough, there was a good bit of algae on the bottom. Checked my chlorine levels FC- 2.5 CC- .5. I checked my PH levels as well and I was surprised to see it was so low. It was at 6.8. Is that normal when Slamming? It was at about 7.6 when I started, so I'm assuming that's what it's from. I'm going to do the OCLT test tonight to see where we're at.

    Thanks again for everyone's help!

    Re: Newbie with Test Results

    High FC levels (above 10) will interfere with pH test but if your FC is 2.5 that's not the problem. I don't remember seeing issues with pH dropping during a SLAM.

    Adjust pH back to 7.4ish first and then resume SLAM.

    Re: Newbie with Test Results

    Would rain effect the FC levels? I did my OLCT test last night. FC was 12.5 at night. I checked this morning and it's 9.5. I realized it rained pretty good last night and wanted to make sure that wouldn't effect the test results.
