    Should I be taking any special action if my CC is at 1.0 (using 0.50 resolution FAS-DPD) for two weeks?

    No visible algae, FC levels are solid , so not sure if this is really a problem or not. Rained once or twice during this time. FC did drift to 5.5ppm (80 CYA) two days ago (bottom of target range is 6.0).

    Bad capacitor

    Thanks y'all for posting this one. Just had the same humming motor not starting and a quick forum search gave me this result. 5 minutes later the capacitor is on order for delivery in 2 days.

    Does algae form a protective barrier?

    Interesting. Thanks for sharing. The membrane deal was new info to me.

    Does algae form a protective barrier?

    Is this true? “When you start off with not enough chlorine the algae forms a protective membrane that makes it harder to kill. It is better to use an algaecide versus the crapshoot on superchlorinating the water exclusively”

    Thanks, found the toggle in the app.

    CSI in Pool Math

    I see this in Pool School: "How is CSI calculated? Very simple – by using the PoolMath tool. Since CSI is primarily calculated by combining pH, TA, CH, and water temperate (among other items), simply enter your test results in PoolMath and refer to the CSI row. The tool will tell you if your...

    SWG chlorine levels

    Yeah from the Chlorine/CYA chart, 3 is the minimum FC level for SWCG pools. Target is 5. Might have just been skirting the edge a bit too much. https://www.troublefreepool.com/blog/2019/01/18/chlorine-cya-chart/ SWCG Pools CYA (Stabilizer) Minimum FC Target FC SLAM FC 60* 3 4 24 70 3 5...

    Dolphin/Maytronics recommendation

    I have the CC Plus. Really like it. I've had it for a year. Not a single quality problem. No maintenance or replacement parts needed so far...not even the filters. And as Jimrahbe said, it pretty much gets everything. I use a SolarBreeze NX surface robot to minimize the amount of debris...

    Questioning Pool ownership

    I'm in Houston. Like San Antonio, it's hot here and the summers are long, and with a spa built-in, you have year-round entertainment. With those young kids, you will absolutely get value out of it. Consider that a wake boat is around 70-140K, the maintenance and use costs are high, and...

    Getting ready to SLAM, but sides of pool look a little off...

    Funny that you said that...I started having a heater problem about a month ago...not sure if it's related. It will light and the burners will ignite for about 10 seconds and then go out. It will retry this cycle 3-4 times and then error out. The manual suggests something is wrong with the...

    Getting ready to SLAM, but sides of pool look a little off...

    I've been diligent about maintaining the pH and have always had it between 7.2-7.7, but I've only had this home for 18 months and it was built in 2010 (and I'm assuming the pool was put in when the house was built). I made the ignorant mistake of relying on Trichlor pucks and Calcium...

    Getting ready to SLAM, but sides of pool look a little off...

    Took me a bit to figure out how to log via the app. Took these measurements after I replaced 4,100 gal of an estimated 20K gal pool. Got the CYA down to 90...still high but more manageable. We're expecting rain so that should add another 1K gallons. FC = 12.5 (I'd added liquid bleach during...

    Getting ready to SLAM, but sides of pool look a little off...

    I was setting up to SLAM to correct a mild algae problem, but measured a very high CYA level. Partially drained the pool to correct the CYA level, and that uncovered numerous light patches on the top edge of the pool walls. Care to venture a guess at what this is about?

    Good enough reason to me. Subscribed to PoolMath app as well. Happy to help those who are happy to help.

    Dolphin T55i/30i/S300i

    Thanks for the pointer on the K-2006-C. Since I'll need a new kit anyway, I'll get the larger test kit. The TF-100 is 1oz bottles for $70. The K-2006-C is 2oz bottles for $107. Seems like the Taylor kit is the more economical option?

    Liquid Chlorine Pump

    This might be a frighteningly ignorant question, but why don't people pull water from their pool to supply their landscape irrigation system (with an appropriate backflow preventer)? As the irrigation system pulls water from the pool drain, you're then constantly replenishing your pool with...

    Do I want CYA?

    Do you find a lot of newbies here getting completely irritated over the proliferation of tablet options with stabilizer enticing people to use them as an easy and low-maintenance way to maintain chlorine levels, only to find the CYA going bonkers down the road? And better yet, why do they put...

    Do I want CYA?

    You're right. I'm just planning for maintaining CYA levels after I complete partial drain and refill. Once I get it back down to 50ppm or so, will it just stay there without any additional stabilizer being added? Or will stabilizer additions only be desirable every few weeks/months to keep in...

    Do I want CYA?

    Is it acceptable to use a TriChlor tab feeder to maintain CYA, rather than add a separate stabilizer?

    Working a light algae problem....

    Latest tests using Taylor K-2006 kit...pH=7.3, TA=80, CYA=130, FC=8-ish Need to get the CYA down before SLAMing so I'm working on that now (partial drain and refill). Pretty sure I had my automatic chlorinator set too high using Trichlor tabs (only had this pool for a few months so still trying...

    Nautilus CC question

    I have the Nautilus CC Plus with the Dual-Filter setup. Have never had to remove anything and the factory filters have done a great job for a year plus. If you can post a photo of your unit hat might help.

    Dolphin T55i/30i/S300i

    Looking to move from the CC Plus to the T55i. I’m attracted to the T55i brushes rotating 2X the speed of the drive treads as a way to brush off light algae growth. The CC brushes are more for locomotion than actual scrubbing. Any T55i owners have feedback on this?

    It’s almost been a year. How has it held up? And do the rotating brushes remove light algae when it does appear?
