    Lost CYA

    OK, I knew I'd get a good answer here. Thank you Marty! Amazing how much less chlorine I need now that it is back to where it belongs.

    Lost CYA

    I had to turn up my SCG all the way up, and should not have to. My TFP SWG pool was at 70 CYA last year, and has, in fact, been 100% trouble free and crystal clear. So I checked my CYA level for giggles, but I was under the assumption you can’t lose CYA unless you lose water, which I have...

    High CYA- possible algae

    1) TFP recommends liquid chlorine, or SWGs, NOT granular. Dry comes with other stuff you probably don't want, like calcium, or CYA.

    Need some help with a little green pool.

    This is good news! What I think is, start your SLAM now. I would definitely get your FC up to 20 ASAP, check it 4 times a day and keep it there until you meet or exceed all 3 criteria. HeRe is why: SLAM criteria: 1) OCLT less than or equal to 1.0--PASS (barely) 2) CC less than or equal to...

    Need some help with a little green pool.

    I don't think there is any such thing as a mini or mega SLAM. You either are at the SLAM level, and are killing algae faster that more is growing, or you are not and you are not. Also, the more quickly you reach SLAM level, the faster you are winning the battle and the FEWER DAYS (sometimes...

    Need some help with a little green pool.

    Look up SMAM in pool School. What it will tell you is to get your PH to 7.2 [I think, so check], and then stop measuring pH because at elevated SLAM levels, the pH test is not valid. And take the AM part of SLAM seriously. That is the key that will get you there.

    SLAM ing 3.0ppm combined chlorine

    OK, the only question left, is: how do you get this stuff out of your water. Again, really great work Dom.

    How the heck did you find that? Another reason to stick with the basics. Great work!

    SLAM ing 3.0ppm combined chlorine

    The only reasonable way to lower CYA is dilution. However, 30 is good! also, your steady vigilance is winning the war. A little more patience, and keep it at SLAM level. You don't have any evidence of any yellow algae, do you?

    SLAM ing 3.0ppm combined chlorine

    Ok, so we go here to determine SLAM levels Pool School - Chlorine / CYA Chart And we see that at 50 CYA, your SLAM level is 20 FC. Safe is anything below 20. I can speculate that at 30, you may be killing critters faster, thus consuming more FC per hour. This is also consistent with you High...

    SLAM ing 3.0ppm combined chlorine

    Oh, and it is OK to swim at anything below SLAM levels. You need not bring it down to 5 to swim. Might be a bit more harsh that you would normally expect.

    SLAM ing 3.0ppm combined chlorine

    OK, this is really quite good. At least from a troubleshooting perspective, your measurements make sense. You are losing FC over night. So there is stuff in your pool that needs neutralizing. This is consistent with a high CC--CC is the result of combining FC and critters. FC+critters=Less...

    Also, if you get a speedster, you will use it till it breaks and then buy another. They are really nice.

    SLAM ing 3.0ppm combined chlorine

    I would highly encourage you to stay the course. The CCs MUST come down. And they can only be there if the FC is oxidizing or killing stuff. Whatever it is, it is something. Some people have had to SLAM for weeks, so I'd suggest you stay the course, have patience, and especially, Lee asking...

    Whew! 90 CYA. Can you drain 20%? Did I see that you have an SWG?

    SLAM ing 3.0ppm combined chlorine

    A few thoughts that may help. Skimming this thread tells me you are fairly new to the key measurements. So I'll suggest you take a look at the TFTest kit videos and the taylor videos. There may be some simple ah-ha moment. For example, your CYA can't be 45. If you follow the directions to the...

    Hot Water and CYA--cheap alternative to liquid?

    OK, so he tried it, with minimally positive results. So it seems hot water is only somewhat better than cold water. Looks like the Sock approach is the good and proven approach.

    Hot Water and CYA--cheap alternative to liquid?

    I was reading the directions on my brothers CYA package, and it says you can dissolve it into hot water, and just poured it in the pool. 1) will CYA dissolve in hot water quickly? 2) if hot is good, will boiling water be better? 3) if so, would you still need to wait a day before you test?

    Slam process question

    The point of a a pool is to enjoy it, right? So if you slide back a couple days but get to enjoy your holiday, that seems like a good compromise. So you will I'll have to SLAM for a couple days longer? Eh, so what? Also, 8 days is not that bad; we have seen SLAMs that take weeks. And yes you...

    Slam process question

    I thnk 500 drops per oz if memory serves me. So that would be 1/5 tho of an oz. I get your point. Maybe stick with 10 ml.

    Slam process question

    If you end your SLAM too soon, you will be back at it. You have to satisfy the 3 criteria Crystal clear water pass OCLT CC less than 0.5 Add an extra day if you are not certain, or you want to be sure. - - - Updated - - - Oh, and I'd go back to 25ml test to get a more precise CC.

    Slam process question

    Suggest you use the 10mm FC test. uses 2.5 times less reagent, and no need for high accuracy during the middle of a SLAM. When your FC starts holding, then you can switch to the more accurate 25mm test.

    OK, first off, your first post! Welcome! Second, will you put a bit about your pool in your signature block? Third, there are some good rules of thumb in pool math that can help you get into the ballpark of a TFP pool. For example: TA: 60-80 -- Your 200 means you are probably chasing pH...

    just switched to TFP

    Ah, OK. So Liquid chlorine. If you want to minimize the amount of water you use, you would be best off lowering your CYA all in one shot. So for example, if you wanted to go from 80 to 40 in a 30k pool, you would need to drain and add 15k total. But if you did it 5% at time, you would need...

    What method are you using to sanitize? Your CYA is a bit high, you may want to lower that unless you are using an SWG.

    TFP--Why does it work so well?

    OK, I've been thinking about this question for awhile. So I'm not looking for lots of rah rahs, and cheering from TFP fans. I'm more interested in the math, facts, chemistry, and data. The TFP approach is really great. My pool is ridiculously crystal clear, and on it's worst day, it looks...

    Pool Won't Clear Up

    Try the tarp method. Buy a piece of plastic that is much larger than your pool, put it over your pool. Now fill above it, and pump out from below it. You can hit your target CYA in one shot. Make sure it is very large. But doesn't need to be thick. The cheapest large piece of plastic from your...
