It's spring - I can tell from all the mud (fortunately not in the pool). I'd like to put on the solar cover and get a head start on warming things up. However, the water's still well below 50F, so our SWCG won't be generating chlorine anytime soon (or so it says on the label). Would it be OK to...

I'm getting ready to put my pool equipment back in service, and I'm not sure about the state of the filter. The cartridges are two years old and are a little ragged, with discoloration from the chlorine (I assume). Are they beaten up enough to need replacement? They look like...

Thanks. The relay vs. actuator module thing was the big (and in retrospect, obvious) thing I missed. So, any of the IntelliTouch personality modules would have enough relays, but valve actuator circuits are going to be interesting. In principle, the i5S+3 personality module could support seven...

Now that I'm about to add some solar collectors, it's time to think about automation. A friend of ours is using manual control, and he's constantly watching the panel and pool temperatures and running out to twiddle the valves. However, the complexity of choosing a system is driving me to think...

CYA is about 40, so the pool calculator says <=15 FC or so should be safe. Thanks! Sim

We went away for a week, and I left our pump running at the lowest setting and the SWCG running at 60%. We got back today, and when I did the FAS/DPD test, the FC reading was 25 ppm. Is there anything I can do, other than shut off the SWCG, take off the solar cover, and wait for the sun to do...

My TF-100 tells me that my TA and FC are a bit high, and my pH is still low. I've cut back on SWCG runtime, and started aerating to raise pH. Should I also lower TA, or is 90 OK? TF-100 readings: FC - 7.5 CC - 0.5 pH - 7.2 TA - 90 CH - 80 CYA - 25 (new pool, still adding stabilizer) Salt -...

Panel on a post, version 2.0. Well, two posts now. [attachment=0:1cckktx8]panel2.png[/attachment:1cckktx8]

That was easy. Dumped a bag (13.5 lbs) of baking soda in the skimmer, TA is now 70 and pH looks just under 7.2.

Got it. 232 oz. of baking soda, and then borax for the pH. Should the baking soda be added all at once, or added and tested over several days? Thank you for the Pool Calculator!

My pool is finally open :-D! The murky pond water I started with is now pretty clear, although my filter isn't especially happy with me. I want to start out by following Water Balance for SWGs. Right now, the SWG isn't working, so I've been adding a little bleach to (hopefully) keep things...

A second post and replace the crosspieces with exterior plywood. I can do that. Thanks, BK. Vermont doesn't do residential inspections, but I'm not trying to abuse that (honest!).
