Bear in mind that CYA requirements can also vary by location, and some of the things here are suggestions that must be tailored to an individual pool. It's a balancing act - when your CYA gets too high, you will have trouble maintaining a high enough chlorine level to be effective. And if it's...

This thread subject line certainly grabbed my attention. If you have actually managed to get water to be un-level, you've really got something! BTW, the quick way to check a bubble level for accuracy is to set it on some surface and look at the bubble position, then turn the level around 180* in...

Yep. Every BBB convert here has this happen eventually. Welcome to the club.

Speaking generally, you should lose none at night, so your total loss should happen during the daytime. Measure the actual drop during the day. That should tell you how much you will need to compensate.

A little outlet tester like this one is REAL handy to have lying around. [attachment=0:3rcvp7gn]outlettester.jpg[/attachment:3rcvp7gn]

If the speakers are wired in parallel, the resistance (actually, impedence, since it is an AC circuit, but I digress) will be lower than 8 ohms. The resistance of two 8 ohm speakers in parallel is 4 ohms, three parallelled would be 2.666 ohms, and six 8 ohm speakers in parallel would be 1.33...

psiflow purchased the app from Jason some time back, and while they indicated early on that they might keep it up, they seem to have just abandoned it. Jason cannot do anything with it anymore, as it belongs to someone else. From page 3 or so of this thread:

Sometimes, suction leaks can be found using running water from a garden hose. Let the water flow onto suspected areas, and watch the bubbles. If the bubbles stop, you're flooding the leaking area with water.

Re: Awwww ****.... lightning? Glad to hear it's all good again. So.. now you wanna know WHY you read 120V on each leg to ground when one leg was obviously dead, huh? It's because the voltage from one breaker travels to the motor, through the motor windings, and back on the other wire, where it...

Samantha, she is fresh out of college (suma cum laude @ Savannah College of Art and Design in sequential arts). She got this idea during her senior year, and she's running with it. She puts a lot of work and heart into the site and each comic, and we're very proud of her.

Re: Deck is finished and the pool has been great for 2 years Wow, that is so super-nice. Where'd you say you lived again? <gets AAA map>

No, that came from XboxLive, and I photoshopped it into a pic from a former client's rooftop.

Thanks, everyone. We're all naturally very proud of her. I don't know *WHERE* she gets her talent... ( From her mother, of course, not from me. :wink: ) Maybe that high-fallutin' art college helped some, I dunno.

I am always amazed at how much feeling and emotion she can show using only the eyes. Darned squid doesn't even HAVE a face.

Hi, gang! My daughter just started her foray into the world of online webcomics. I'd like to invite everyone to visit www.lifewithsquid.com and check out her work. Thanks!

Re: Awwww ****.... lightning? Make sure you check not only from each power lug to ground/neutral, but actually check for 220V from lug-to-lug.

The wire that bonds the outer case of the motor is [should be] connected to a bonding loop underground. It should make a continuous loop around the pool, and should connect to the re-bar in the concrete. It should connect to any metal [conductive] parts of the pool itself. All metal or...

Sorry, I did not mean to imply that your post was somehow bad, wrong, or remiss. I just wanted to clarify the static-vs-continuous thing, Then, as usual, having started typing, I couldn't stop spouting until a few paragraphs had passed.

Most motors have a thermal device in the windings which will open the circuit when the temperature gets too high. This is purely a safety device designed to prevent destruction and fire, it should never trigger unless something is wrong. Way wrong. Low voltage could cause overheating, but be...

The comparison to a static shock may be misleading. A static shock occurs when a charge builds up and discharges through someone, but once the discharge happens, the charge is dissipated, and it's done. This is not the case with a current in an unbonded pool, as the voltage potential will not...

Re: Alternative sanitizers and "chemical free" pools--The Tr I don't really know, maybe nothing. Maybe the concentrations are just so low that they don't pose an immanent threat unless one is directly involved with a contamination area. Maybe the oceans are slowly filling with nasty...

It really doesn't TAKE all kinds, we just HAVE all kinds.

It depends. In a *healthy* person, there should be no pathogens in the vomit. As a side note, a healthy person's pee is sterile, so there is really little infection issue, just nitrogen/urea/cc. But that is for healthy folks, and if a kid is barfing, he may not be healthy, thus there may be...

There is about 60% as much CYA as Chlorine, so for every 10ppm of FC you get from Trichlor, you get 6ppm CYA.

Obviously, #12 is bigger then #14, and there is less resistance to current flow in the bigger wire. In practical terms, there will be less voltage 'lost' by the extension cord with a bigger wire. If you have 120 volts at the receptacle, and your motor draws 10 amps, then a 100 ft extension...
