Hi Richard and thanks for your comments. I took the pressure gauge/air bleed off and renewed the little 'o' seals just because I decided I just as well renew them as I was renewing all other the rings and gaskets I could think of! It was a good job done anyway so I don't view that as a wasted...

Hello again, thanks to you wonderful TFP folk the water chemistry problems I had have been resolved and all as stayed fine... but unfortunately a problem of a rather different nature has now developed. I've read all the threads I can find on air in filter problems but nothing on the crazy...

Sounds good and thanks for your comments chem geek. Just to give an update on my problem. It took six days of following the TFT method of clearing up cloudy going on green pool water to get there, but after initially underestimating how fast chlorine got eaten up in the first couple of days and...

chem geek, thank you for your input. No wonder my terminology caused confusion! Your comments about CC are also very pertinent, I use a solar cover and the pool is probably covered over at least two days a week. It's gonna be nights only from now on! Thanks also for the Palintest info. I've...

Ha ha! cheers then buddy and thanks again from not so sunny Bournemouth!

Thanks Tim, brilliant. I'd forgotten ChemGeek's expanded chart existed and was working from my copy of the simplified one. Thanks for pointing me in right direction. The number I was looking for is given as FC at 8.3. I can test regularly every 2-3 hrs so no problem ensuring daylight isn't...

Thanks guys, the breakpoint I was referring to is the CYA/chlorine oxidisation point as stated in Chem Geeks chart. I do realise the importance of normaly keeping CYA to at least 30ppm which according to the chart (means a breakpoint of 12ppm) CYA at 32ppm is where it normaly is and works just...

Thanks for such a quick reply tim5055, I didn't mean doing a limited slam. I realise I have to get through the breakpoint AND keep it there to meet the three endgame conditions, it's just that I don't know the breakpoint I need to get to with the CYA so low at present.

Hi folks, I joined this great site several years ago and have often followed the various topics and always tried to follow your TFP methods. As a consequence I don't normally have any problems, it's a very rare occasion when I've had to slam the pool. I've always slammed to breakpoint as soon as...

You guys are brilliant! I don't test near the returns & I even stay away from even being opposite the returns, I test on the far side near the corner of the deep end & near the corner of the shallow end. I also test when the pump is off & the water has calmed down & is motionless. I've tested...

Yes I accept that normal dip test strips may not be totally accurate but the makers of the reader strips make very specific claims of the +/- accuracy, but even allowing for that not being legitimate the fact remains that day after day the deep end (tested first) TA reads 90 and the shallow end...

Hi & thank you for the comments. I never was a strong believer in the slug method but I tried in anyway just to see if it was more effective. It wasn't! Firstly my testing methods: Up until recently... which is when I noticed I had a difference in TA readings, I used a simple tablet & vial kit...

Hi, I'm getting TA = 148 at the deep end & TA = 90 at the shallow end. The pool is an outside, in ground, typical liner pool with inward sloping sides to a 7' 'hopper' shaped deep end L=30' W=15' (about 15,000 imp. gallons) The rest of the equipment consists of multi-port valve sand filter, gas...
