Allen, The first year I just let everything run 24/7. Year 2 (last year) I started shutting things down for 3-4 hours at night, and that helped. Mid season I went to manually turning my HP on at about 9 or 10am every day which also helped (I might try to get this on a timer somehow - I do have...

That’s helpful. I’ll check it out, thank you. My personal bill to run my heat pump monthly is in the $300-$400 range and that seems insane to me. I need to do more homework on it. Also, 2 friends are building pools and I want to give them the most accurate information I can.

Hey all, I’ve been using TFP for a while now and I’m a supporter... About a year ago I was frustrated with the insane cost of running my heat pump and when I searched here I found some rather technical articles that clearly outlined when and why a heat pump can be more expensive than a gas...

OK, so I just went through this using the TA method and I assume it worked. Looks like I'm about 5,000 gallons less than what my builder told me. To confirm that it's right, I'm going to start using the new data of 28,000 gallons vs 33,000 gallons to set up the app and calculate chemicals...

This is all super helpful. I’m going to have to set up on day and do this. Maybe tomorrow - seems strange to say this will be a “fun” project.

So here’s my thought and a question: I’ve been trying to determine my exact pool size (my pool builder just doesn’t think it’s important so I never get a solid answer). They’ve said it’s around 33k. BUT, when I add acid to bring down my PH, it seems to WAY overshoot. Granted, I haven’t been...

@Aqua Lab Rat & @onBalance Now that I'm getting deeper into this I went back and read the TFP post here: Chlorine/CYA Chart And reference 3 really stood out to me: "Most saltwater chlorine generator (SWG) pools appear to prevent algae at a minimum FC level of 4.5% of the CYA level as compared...

@Aqua Lab Rat This is exactly where I'm struggling - most of the "recommended levels" show it at around 70ppm for my pool. SWCG, IG, plaster, etc. (you can see my sig) But the papers point to what you're saying. @onBalance As I try to put all of this together, it sounds like CYA not only...

@Donldson, thanks - It’s funny to read your response (and likely very accurate), if I read an article like that by someone trying to sell alternative solutions in my industry I’d see right through it, but here I missed it. Just glad we have such open and honest people here at TFP - open to...

Thanks for letting me geek out on this stuff, looking forward to digging through that thread. Ya know what - I didn’t even look at what they were selling...Just read the article and immediately came here for the truth. Thanks!

I just read this article and I'm very interested in thoughts around it: Cyanuric acid: friend or foe of swimming pools? Quote from the article: Over the years, numerous independent and academic research has come to show that when cyanuric levels build up in the pool, ORP levels consistently...
