The Aiper S1 Scuba is on sale on Amazon right now for $788 Canadian which is about US$560. Is that a good deal? Are most that have bought the unit happy with its performance? I have had a dolphin S300 for six years that cost me $1300 Canadian. It is starting to be less effective at picking up...

You are always supposed to shut your heater off about 5-10 minutes before your pump so that the heater has a chance to cool down while the water is still circulating and you don't have extremely hot water in the heat exchanger when the water isn't moving. What happens when you have an...

But you still may need a way of pulling data from a device. I could be wrong, but I didn't think that there was a way to digitally interface with my Jandy Aquapure 1400 to pull data like salt reading, temperature, flow sensor and percentage level. And the same with my Raypak heater. I don't...

You gave it above! I was showing the work on how you get to 5700 gallons.

Not sure but the prices of automation for a pool seems like such a ripoff when you could duplicate it with hardware worth $50. I know that these are low volume luxury items but it still seems like a ripoff to pay thousands of dollars for what is often limited functionality. And I am not sure...

Another way to look at it is 18' round and 3' deep is 3.014*(18/2)^2*3 cubic feet or 463 ft^3 as the volume of a cylinder is pi*r^2*h. 1 cubic foot is 7.48 gallons. 463*7.48=5707

Like Doctor Johnnie Fever. I can spot the black dot when the CYA level is 100 through 10 feet of cloudy water.

Which is almost 2.5X of the third party replacement which is $409. I prefer the transparency of the third party cell. Mine has lasted almost four years so even if it dies soon it was a good deal.

You will probably get an even bigger response here that he is a complete idiot and has no idea what he is talking about. The salt cell will not have to work overtime with higher CYA around ~70 and FC around 3 which are the low end of the suggested levels for CYA and FC with a SWCG. The reason...

I do my tests out in my pool cabana with a fridge that is well stocked with adult beverages. And if you have enough of them then the black dots begin multiplying...

This is another reason why it is nice to have a SWCG.

The Sonoff THR320D is a smart switch that can control a load up to 20A and which also has a Dry Contact relay. I have flashed this with Tasmota and I am using this device as a smart switch to remotely turn my pump on and off and to control the heater via the dry contact relay connected to my...

True, but I am thinking more from Mon-Fri when the pool isn't normally used and is covered with the solar cover.

Thanks, will do. We have a new pricing regime here in Ontario called ULO. Overnight electricity is 2.8c/kWh. Peak from 4-9pm is 28.6c/kWh. The rest of the weekday is at 12.2c/kWh. Weekend daytime rate is 8.7c/kWh. Would there be any benefit to running the pump for an hour or two in the...

True, but do I lose more chlorine during the day with a solar cover on the pool all day long?

I would prefer to run my pool pump at night as my electricity is WAY less overnight. My pool is covered most days by a solar cover. Any downside to the pump not running during the day. I have a SWCG as well so I need to run the pump enough so that it is generating enough chlorine, which I can...

I bought one from the SaltPoolStore that is about half the price of the official Jandy cell. Looking at my emails I bought it in May of 2022 and it is still working. Jandy 3 Port Replacement Cells I think there is thread on here about these. edit: Here is the thread on these third party...

I read that link. It says: So it seems like it isn't a big deal if it is just once per year. And with some heaters it is below 50F, which must be pretty extreme. I am in Toronto and when my pool opened a few days ago it was 53F, now it is 57F. But how would you ever operate the heater for...

Do you mean when the water is below 68F or the air temperature is below 68F? And if it is the water then would you be running it that much when the water temperature is below 68F? Once you get the temperature to 68F then it would never be running continuously below 68F, unless you shut it off...

I am pretty late in closing and pretty early in closing. Lots of people here close in early Sep and don't open until late May or early June. The problem with opening earlier is that you may have more risk of below zero temperatures.

On the doc here on opening your pool (Opening your pool- An easy to follow guide) it says: My pool was just opened with the water at 53F. I live in Toronto and the pool was closed in mid-October. I have a mesh cover. Every year when my pool is opened it is pretty green and gross, and I don't...

Thanks for the advice I will do that, but I think first I want to get in cleaned up as much as possible.

I live in Toronto. My pool was uncovered a few days ago (I have a mesh safety cover). As is always the case upon uncovering the pool is cloudy and greenish and had some debris including leaves, dirt, etc. So I have shocked it and it is clearing up. It has been vacuumed but I still need to do...

Thanks!

Thanks, I will do that. I already did lube the main pump basket O-ring as my first step as I thought that was the problem. Here's the blowup of my Hayward Super II pump - I think it only has one drain plug labelled as 10 in this diagram. Or is there also one on the side shown below the main...

My pool opened this week. This was done by a service - I maintain my pool myself but I have them open and close the pool. After opening I was getting a lot of air from the return jets and lots of air in the pump basket. It appears that the problem was that the drain plug on my pump (Hayward...

No borates. The only thing I have in my tub is tap water salt and MA. Occasionally I add a bit of baking soda to get TA up but it usually screws up my pH. So I continue to live with TA of 40-50. If I remember to close the air intake then the pH just increases very slowly - it stayed around...

I add pretty small amounts of acid to get my pH down to about 7.5. It rarely gets lower than that. And my TA tends to sit around 30-40 when my pH is below 8.

I am using baking soda to raise my TA, but it raises pH as well. To reduce pH I use MA, but it causes my TA to plummet.
