Hi there all. I am thinking about taking the plunge and purchasing a CircuPool RJ-60 salt water generator. I used my amazing artistic talent & mocked-up the best location for it at the pool filter (sorry, but once you see my bad art...you can't unsee it! Haha.). I have two return lines. The...

Hey there fellow TFPers. I've facing an issue here, and just as I'm going to close the pool. But I think that may work out well, as I have to lower the water anyway. The screws holding the skimmer in place are rusting after 40 years. And yes, I tested and there is metal in my pool water. I'm...

Hi all. Happy Summer '22. I've done two partial drain & fills over the years in an effort to remove metals. But it's too costly to keep doing. So I purchased a CuLator bag, and hope to get the remaining .45 iron out of the water. This is just a question about your thoughts on the process...

Hey all. Was hoping that some of our chemist-oriented brethren can assist with some info on this. Yes, I admit...I have so far this season been using expired Cyanuric Acid Reagent. My question is...how can I tell if it has actually "gone bad"? When using it to test for CYA levels, does a "bad"...

Hi everyone! I don't know why....but I've had such poor luck with winter covers over the last few years. Has quality really dropped? Winter covers int he past seemed to last for 8+ years with no problems. I would like to ask you for some help & advice, in particular those of you that have in...

Hi brethren and thanks for your help & ideas. I have used the TFP technique for two full seasons (love it). I've documented the amount of days each season to complete SLAM, the amount of liquid chlorine needed, etc. Last season, it took 7 days to complete SLAM. 7 days of the sand filter running...

Hello all, Our in ground pool is over 30 years old. It's actually still in pretty great shape, but in some sections the metal coping has holes in it. I gather this was caused by rusting over the years. I've posted a photo. Would anyone have any suggestions as to how best to repair this? Is...

Hey brethren. I am comparing the Hayward PoolVac XL and the Navigator Pro. ...and as far as I can tell there is not much difference? The only difference I can find in Hayward's product description is in the "Programmed Cleaning": Navigator Pro has "Exclusive SmartDrive® preprogrammed steering...

Hey all! Looking over my notes, last year (2018 season) it took 9 days to get through SLAM. Which meant the sand filter ran 24 hours a day for that entire time. Also, in total it took just over 24 gallons of liquid CL (10%) to do it. Can I speed-up this whole SLAM process? (Let's assume the...

Hi and happy 2018 pool season. I'm in the Northeast and opened the pool a week and a half ago (I do a short pool season) This is my second year following the TFP method. But I was hoping if some of the seasoned members could give me some ideas as to why I am using SO MUCH liquid chlorine during...

Where in the range is best? The "recommended Cyanuric Acid" range for my pool is "30 to 50". Does that mean that the optimal/best level is right in the middle, in my case "40"? Or, does it mean that if CYA is anywhere in the 30 to 50 range that it doesn't matter much, that it's "fine"...

Hi everyone. I'm excited, as I've followed TPF for a long time but this is my first season where I'm doing all Liquid CL & following the TFP method. I opened the pool, and it was already quite clear.I have a FAS-DPD kit now. The FC was pretty much zero. I started the SLAM method. My CYA is...

I'm interested in your thoughts as to if you think this could work. 1.) I have iron in my pool. The plastic white step entry into the shallow end is entirely stained, the white plastic fittings are stained, the filter basket, as well as the deep-end "Joints" where the bottoms meets the sides...

Do high levels of CYA plus high levels of Chlorine promote metals from coming out of water solution, thus promote staining? I ask because I "think" that's what the Pool Store told me after they tested my water. And I do have high levels of both. They definitely said High CYA...but I'm unsure...

Hello all. Thank you for reading this and for your advice. I have been trying to learn more about the TFPC method & utilize info where I can. Is there a conversion for pounds of granulated Chlorine to gallons of Liquid Bleach (~12%)? I know this is a novice question. I checked the Pool...

Hello all! I have a Hayward S240 [s:83xnukbg]pump[/s:83xnukbg] sand filter , and lost the manual. The Hayward website doesn't have one either. I contacted them and they said they'd snail mail a copy to me...but that was almost two months ago. And I contacted them again to remind them a few...
