Like the subject line, any link I click just takes me to the /blog homepage. If I do a forum search, I can get to threads, unless they're posts by TFP (like Pool School articles, etc). Is it just me? I've turned off Ghostery, etc, just running a plain-jane version of Firefox on a Win10 machine.

I also have ridiculously high TA, and I've learned not to worry so much about it. The fill water routinely tests 400-ish, and the pH is fairly stable. The Calcium is a tad high (don't recall the last test result), but no issues. Since I started reading TFP and quit granulated chlorine and then...

I've got 2 Triton II TR-140 filters, installed 1985, and both have their original clear domes (p/n 15-4678) - which I love because you can SEE what's going on inside the filter. One of my domes got cracked when the filter plugged (sucking mud from a cracked skimmer line), and the pressure spike...

Yup, looks like a peristaltic is the way to go. I have zero experience with them, anybody have some suggestions on what to look for?

Note that to get the CYA down from 90 to 50 (just to pick a target), you're going to have to replace 44% of the water. That's a LOT of vacuuming... But with a lower CYA, you'll save a bundle on chlorine.

Will do, no worries. I started them together, then split them apart - but together works just as well! Thanks for the Liquidator explanation and other info, your previous posts were some of the ones that got me thinking along this line. With the surrounding trees and their daily deposits...

After reading up on ways to auto-feed liquid chlorine, I'm intrigued with the Liquidator...only thing is, I buy liquid chlorine by the 55-gallon drum (it's WAY cheaper, and smaller carboys are not available around here, and I'd like something bigger than the 8-gallon Liquidator tank). My goal...

DIY "Mega-Liquidator"? Here's what I'm thinking of putting in the pump-house of the Camp's 144,000-gallon pool, trying to feed around 1.3 gallons of CL per day. Take a 55-gallon drum, maybe fit some clear hose from top side to bottom side of the drum as a sight gauge of the CL depth. Drill...

chemgeeks's CYA chart indicates a target FC of 5.7 with a CYA of 50, you may be "riding a bit low" at 5.0... After you do what linen suggested, with a CYA of I'd let the FC drop down and keep it at 7.5 or 8 couple of days and watch those trouble spots. Easier to back off on the FC than play...

The above is good advice, if it's worse after vacuuming then either you're just stirring it up or your filter isn't catching it. Since your CYA is high, I'd suggest slowly vacuuming to waste if possible, or getting a separate pump and using it to vacuum dirt/water out of the system. That way...

Thanks chemgeek, that answers my questions nicely!

WOW!!! So that's the goal then, huh? Hmm... I've got this outboard motor.... :shock:

Thanks for the info! :cheers: I guess my basic question is this: What are the practical differences between CPO, CMS, CMT, CSP, CPT, etc?

Texas Department of State Health Services ("Dishes") rules for commercial or public pools, since this one is at a Church Camp and gets rented out during the summer. http://info.sos.state.tx.us/pls/pub/rea ... sch=L&rl=Y I know... "Land of the free..." harrumph!

That may well be the case, since this pool hasn't been drained since Aug '07 (now why didn't I think of that???) Anybody see a reason to be concerned? CSI as per the pool calculator is -0.01, the target? is -0.22.

There's never really been enough water pressure or flow to feed my slide, so I recently put my Harbor Freight utility pump to work - 3000GPH makes a HUGE difference! Then I got to thinking; "hey, lookit all those bubbles - that oughta be a good way to aerate and get the pH back up after I dose...

Using my TF-100 kit w/ speedstir, today I tested not only the pool, but also the water coming out of the well I use to fill/replenish, and here are the results: Well FC = 0 CYA = 0 pH = 7.2 TA = 440-450 CH = 350 Pool FC = 11.5 CC = 0 CYA = 60 pH = 7.2 TA = 120 CH = 525 No real surprises there...

No argument there, I'm looking for a way to track results over time on something other than a piece of paper (that gets wet, wrinkled, lost, etc...) BTW, I settled on the iphone app "Spreadsheet". It's basically an iphone version of MS Excel, and can import/export with my desktop rather easily...

THANKS for the help, you guys and this site are terrific!

Thanks for the tips! I've got a speedstir, it's a wonderful gadget/tool. Ok, after doing the fading endpoint, using 10ml instead of 25, mixing distiller water, and trying pings suggestion, heres what i found. The basic "fading endpoint" directions helped, but not enough for confidence. Both...

Re: Brushing - What does it do and how hard should you brush I did that very thing 2 weeks ago, bought a new brush and moved my old WW onto it. The outboard screws didn't *quite* line up, but not enough to make a significant difference once I got them started.

Re: Brushing - What does it do and how hard should you brush I'd never heard of the King Fin before just now, looks like a good idea for walls. I've used a Wall Whale for a couple years now, and love it for the sides and bottom. One area where I'd thing the Whale would be better is where...

Thanks for the pointer, those extended kit directions are terrific, and sparked a lot of other good reading! :cheers:

Looking in the iphone store, looks like there are several spreadsheet apps that would work well with Excel... I think I'm going to end up using: * an iPhone spreadsheet one to log and track test results, uploading it to Excel on my desktop if/when I want to graph or take a detailed look at...

With the TF-100 kit's CH test, it says to count drops until the sample turns from red to blue. When I test for CH, the sample starts off pink, and goes to light purple at 36 drops, but it takes a total of 44-46 drops to get the purple to slowly change to an actual light blue. Same results with...

Seems like there aren't many decent iphone apps out there... Heck, I'd be happy with one that would just keep a record of test results and corrective actions over time. Graphing them would be a bonus - I think I'll go look for an iphone data graphing app...

Yeah, I'm in the middle of composing a reply to Texas Health Dept survey, asking them to at least look into the CYA / FC relationship and revise their min/max FC standards...

So...I've been maintaining this Camp pool and learning about pool chemistry for 5 years now, and one of my Board Members asked me the other day if I was interested in becoming a Certified Pool Operator. I hadn't thought about it, but I've been looking into some sort of professional pool training...

Unusual animals = brown bat, rat snake, armadillo (still alive, but completely worn out from treading water in the wading pool) Finding the rat snake was a heart-stopper, as I'd just hand-scooped a TON of leaves out of 3 skimmers into a 5-gallon bucket with my hand. THEN I see the snake in the...

Hilarious! btw, my TF-100 test kit arrived today, and now I'm doig this :brickwall: because I didn't get one much earlier in my life. :lovetfp:
