Yes. The drop test in the TF-Pro test kit. Water is 64F

So my CL measured at 10 today. It's been going up pretty consistently, despite having changed my SWG from 50% to 30%. This morning I dropped my SWG down to 15% to see if that helps. I find it really weird that CL is going up seemingly just as fast despite lowering the percentage. My pool math...

Oh, that's a relief. I thought I had a leak somewhere.

So, I noticed a new problem just now. There's small bubbles coming out of only one return jet in the pool. And it doesn't happen 100% of the time. It comes and goes. Before asking here, I did a google search and found this thread...

Thanks guys. I know a lot of this is mindset... I still put too much importance on small numbers. Hopefully I can relax a bit about this as I get more experience. Just yesterday my wife asked me why I'm testing every day lol. I still don't have a good "feel" for my pool yet. I turned my SWG...

I remember before I used the SWG and had to add liquid CL by hand, it was definitely down more than 1.0 per day. More in the realm of 3.0. So that's one reason why I'm confused by the calculated result.

Using pool math, I did Effects of Adding and used these values: Pool Volume: 19440 Chemical Additions: SWG 24 hour SWG output: 1 To Calculate: Free Chlorine Generated SWG%: 50% Pump Run Time: 16 hours Says it raises FC by 2.1 I'm not sure how to use this information. I think the missing factor...

My head is spinning a little bit reading the page you linked... I don't know what CPVC is, I don't know what it means by "Dope" for threaded fittings. I am just not knowledgeable enough to understand a lot of this advice. I'm not plumbing my whole equipment pad. I was thinking 3-way because...

@ajw22 What pipe glue and cleaner do you recommend for joining the diverter valve and PVC? This is the valve I was going to get. The existing PVC is 2". https://www.amazon.com/Jandy-4717-3-Port-Positive-NeverLube/dp/B001I7HZ20/

The further reading page you linked said to use a ball valve. That's why I was going to use it. But I guess I can order a 3 way jandy valve instead. Thanks for the tip.

Maybe I'm using wrong terminology here? I called them "vials" but I guess they could be tubes too. They're plastic and cylindrical with ml markers on them. I do have a "viewing tube" for CYA as well. But as far as what I use on top of the stirrer (which I also have), just two. And only one stir...

I didn't ask my question properly, sorry. I was asking if it affects the other, non-chlorine tests. For example, TA and CH. My TF-100 test kit only came with 2 vials: One for CL only and the other for everything else.

Salt test came back today at 2800. Aquapure shows 2900. Earlier when salt was 3000, aquapure showed 3100. I think the aquapure sensor is pretty accurate; maybe there's no need to do the drop test for salt? Also, the salt test leaves a white/chalky residue at the bottom of the non-chlorine test...

Thanks ajw. I think I will go with the valve. Since the muffler is 1", I will try a PVC tee that downsizes from 2" to 1" and just use a 1" ball valve. I'm not a plumber but seems like that should work.

Is there a way to turn down the blower? It's not horrible, but seems a bit much sometimes. And it tends to cause some water to splash over the sides of the spa. I've read that it typically means the blower is too big for the spa; but I'm not sure. Is it adjustable?

Regarding AquaLink scheduling: What happens if, say, Spillover mode kicks in while I'm enjoying the spa in Spa Mode? Will it switch over to spillover anyway? Or is it smart enough to know not to do that if it isn't in pool mode? I want to ask the question more broadly, because everything I've...

What should my strategy be for the SWG adjustments? I tested CL today and it's up 0.5 PPM from yesterday (it's at 5.5 right now). So I definitely see it going up. What I'd like to know is: - What PPM am I trying to target? - What do I do with the SWG when I hit that target? - I'm worried about...

I just want to be clear. I did not turn it on until all the salt was dissolved in the water. I will turn it off though and wait a few days. I was out of chlorine and wanted to see if it could save me some trips to town.

I already turned the cell on. Is there a reason it isn't supposed to be on right now?

Today I added 9 bags of salt and I'm at 3100-ish salt level. I have 4 bags of salt left. What is my target salt level? Supposed to be 2.6k - 3.8k but we said we are creeping up to some number and I'm not sure what that number is. Also added 5.3lbs of CYA. Using pool math, it suggested that...

Quick measurements of the spa in inches: 140x57x42 Comes out to about 1400 gallons if it were rectangular. I chopped off 20% because it's bean-shaped and there is a bench that goes around 70% of it. That comes out to about 1150 gallons. Running at 2000 rpm, I'm not sure how long it needs to...

Are you suggesting that I use my heater to determine roughly what RPM equals 40GPM?

There's this constant red dust/sand everywhere along the pool, but especially bad on the steps, benches, and tanning ledges. It's very pronounced when I brush it off (red/brown cloud underwater). It's been there since the pool got filled. I assume this isn't algae, but just sand getting in the...

Thanks. I don't know the signs of algae, so now might be a good time to learn. Any tips? Is it complicated? I wish I could be as mathematical with my spa, but I don't know how many gallons are in it. And not only that I don't know the GPM for a particular RPM. I'll share my schedule here. It's...

I found a post from you, about 4 years ago or so, where you said you had yours set up for 30 minutes at the start of the day, 15 in the middle, and 30 at the end. The advice given later in that thread was that you could get away with removing the one that runs 15 minutes in the middle of the...

Here is a video of the Spillover at 1750. Still seems too fast to me but I can try going up. https://streamable.com/6s2pf7

These are the speeds I'm going with for now, just to make sure my pool is a lower speed than everything else: EDIT: Misread your question. About 1750 is the max. That's why I have it set there. I sat outside with my laptop and went down by increments of 250 until I found something that looked...

I understand that now. It's just unfortunate that I have to choose between insufficient skimming in my pool or niagara falls for my spillover

Ok I just tested pool mode at 1500 and spa at the same 1750 and it indeed did work and switch over as it should. That's pretty frustrating. Why would Aqualink arbitrarily decide we don't want to lower RPMs when we switch to something? I guess the only option, assuming it works, is to maybe try...
