    Trouble keeping FC high enough

    Hello all. I have an approx. 10,000 Gallon vinyl pool. Pool builder supplied / installed an IC-20. CYA of 80. I've been running the IC20 at 100% from 8 AM until 8 PM. Per PoolMath this should produce approximately 4 ppm FC. Most daily testing only showed around 3 ppm mid-day ish in the...

    How do you measure / dose your liquid chlorine?

    So I have a 400 USG tub, and a 10k USG pool. The pool is Salt and works "swimmingly." I tried salt in the tub, and it corroded my heater tube to the point it was riddled with holes. I've replaced the heater, and I'd like to avoid that same problem again. As such, I'll go with straight...

    Pool clear when opened, OCLT is good. I'm all set to start with "normal" balancing, right?

    So I opened my pool to nice and clear water. FC was around 8. OCLT is successful. Am I right to assume I can just start balancing like normal now? Still too cold for SWCG. Today: Current Target FC 4.0 5.0 CC 0.0 0.0 pH 7.5 7.6 TA 70 CH 175 CYA 50 70 Salt...

    So I went with salt, and now I have a leak

    So my spa manual specifically states “using third party salt systems voids the warranty.” I thought I knew better and went with salt. Now I have a leak from the “heat exchanger”. Any thoughts? call the manufacturer and play dumb?

    Pentair Clean & Clear Plus 420 filter element lifetime?

    So I had my pool installed last year, and started up in May. I ran the pool all summer with great water chemistry (thanks). I had the pool builder close to maintain warranty for the ridiculous price of $400 CAD (around $320 USD). I'll be opening the pool myself. So I opened up my filter and...

    Any Canadian's want a TF-100?

    I need a refill, and would like to save on shipping. I'll be doing a US trip and would be willing to bring one back.

    New tub arriving on Monday

    So we have our tub being delivered on Monday. Very excited to finally get it, and just in time for fall! We have a salt water pool with the Intellichlor and things have gone mostly smooth for the summer. Bromine is the “de facto” standard for spa’s, but since we have a chlorine pool should we...

    New pool owner, SWG questions

    So our pool was installed, and started up a month ago. Builder dumped in some chlorine, and salt, and left us to our own devices. Things have been going pretty well, you can view my Pool Math logs in my profile. I've been trying to decide if it's better to run the pump longer with a lower SWG...

    Waterfall as aeration?

    So yesterday, I had a pH of 7.8 and TA of 120. I added 900 mL 31.45% Muriatic Acid, and this morning I'm showing pH 7.2, TA 110. I'm working on getting the TA down while keeping pH within acceptable limits. I have two returns and a waterfall, so I'll plan on using those for aeration. How...
