These are a couple. There are some positive reviews too.

I had two M300i's each which only lasted about 2.5 years. I'd never buy another.

Down the road when you're ready to do some pool upgrades I'd get the grass line further back from the pool coping.

Wondering if there is another issue? Noticing the rpm to keep good flow through my salt cell needs to be higher. Run the pool 8am to 8pm. Had to bump the vsp up to 2600 rpm otherwise the flow was blinking red on the pentair salt cell. Cleaned skimmers and the cartridge filter, then was able to get it down to 2200 rpm. Then a few days later I have to keep bumping the rpm. Back now to 2500rpm in order to get adequate flow through the salt cell. The filter had a lot of crud in it and looked somewhat “weathered”. I replaced it January of 2024. Filter issue? Could this be an indication that the salt cell needs to be cleaned? It’s generating chlorine fine, as long as flow is good.

If the flow is good right after you clean the filter, but then gets worse over a few days, I'd suspect that algae is clogging the filter. Especially because your filter is the small size that Florida builders apparently prefer.

Have you performed an Overnight Chlorine Loss Test to determine whether there's algae in your pool?

Do you have the typical Florida tiny sized filter? That may be one problem. If the FC has been low, a clogging filter can indicate an upcoming algae outbreak. The filters themselves should last many years and properly sized filters should go a whole season without cleaning unless you have an overly dirty environment around the pool.

I'd say after the next 24 hours turn the cell on very low so you'll slide in to where you want to land.

Hi there. I have a skimmer basket that is on grass. A previous contractor put pavers standing up around It and It looked hideous. I just pulled them out. Any ideas on what I can do around the square? I was thinking putting more coping stones around It but maybe overskill. What about some 2/4” stones? Any other ideas?

I guess the purpose is to stop lawn mowers from going on It and potentially breaking It.

The skimmer is supposed to be concrete attached to the pool. Are those small rocks mortared into place?

Maybe get a variable speed motor.

As of August 2006 a common date code format for all motors is being used.

It consists of seven alpha-numeric characters.

The first three characters represent the day of the year based on the Julian calendar, the next two the year, and the last two the plant code.

For example, 123064M, would mean the 123rd day of 2006 (May 3, 2006) in Regal’s Juarez IGMEX4 plant.

See post #8.

Dip switch 2 is on and it looks like there is a 2-speed relay in the lower right.


AUX2 should change the pump to low speed.

FWIW, a lot of helpful information about ph meters and similar test instruments can be found on forums for fish aquarium enthusiasts. Unlike one’s pool chemistry which allows more latitude in use of reagents to get close ballpark readings, aquarium owners have to attain water specs with more accuracy. It’s a delicate balancing act with only minor movement in their water chemistry that can mean losing potentially thousands invested in some of the more rare, exotic species.

Pool looks great! I just realized, you used same builder as me. Empire?? We are finished too, just waiting for our sod to be installed by our landscaper.

4 PPM per day FC loss is right in the ballpark to be expected.

I’m working on a mock build for my new filter and pump.

Strange that the pressure gauge will make the difference. As @Jimrahbe said lets wait and see.

last year I calculated my GPM, then figured out the speed I needed to turn the pool over 3 times.

It's a nice thought "pool turnover" but here on the forum we don't do anything because of turnover which is a myth. We run the pump to get enough chlorine into the water and that would be enough. The rest of the pump time is owner preference for filtering, skimming and the like. A vsp allows you to run more efficient so it affords you if you like to run 24/7 which lots of us do and at the same time we have the SWCG run at a lower percent along with it. The water remains very clear because of constant filtering.

I do not seem to find an installation manual for the iQ30 but I do see one for iQ20. I presume they are pretty much the same except the 30 has the newer antenna and that in terms of hardware

Click to expand...

Correct. There is a registration number on the antenna and on a place card contained in the package. That is needed to register the new antenna/PCB in the iAquaLink app. The only difference between 2.0 and 3.0 is that 3.0 is improved to work with MESH networks such as Eero.

AmberCrest said:

I guess it will be pretty much a 1:1 swap from the old board to the new board?
In terms of programming... As I cannot access the current board, I really have no idea what sort of programs exist so might I ask about some generalities?

Click to expand...

Yes. Take of picture of the connections on the old PCB and also of the dipswitches on the left of the board.
Don’t worry about the current programming as you want to start fresh once everything is installed.

There are four control valves, two are motorized.
In terms of flow to the pump:
#1) [manual valve] selects between the pool main drain and the pool skimmer
#2 {motorized valve} selects between valve#1 and the Spa drain
Flow from the pump:
#3 [motorized] I believe selects between pool return and Spa return (these are not labeled)
#4[manual valve] I am guessing this is where the blower connects in for the Spa

Click to expand...

#1 is to set suction between main drain and skimmers. I had mine set 80% open to skimmer and 20% to main drain. This is adjustable over time.
#2 This will plug into the INTAKE socket on the PCB. It will auto rotate when selecting Pool or Spa mode. It is firmware programmed so can not be changed.
#3 same as #2 but plug into the RETURN socket on PCB.
#4 - would like to see a photo of this and the whole equipment pad. It could be an spillover valve to allow the spa to spillover into the pool when the system is in POOL mode.

AmberCrest said:

Regarding the pump... It would seem to be a 2-speed: SP4020X252NS however, I have not confirmed that the motor actually is a 2- speed motor and I just discovered there are multiple generations of that pump - this one seems to be 2005.

The current dipswitches may indicate if it is a 2 speed pump. Take a photo of current PCB dipswitches.

It’s a bit early to do anything with the pool here in Michigan but, we had a beautiful day and I did a couple things. First, I replaced a tie down spring on my safety cover. I got off line this winter and hit it with my snow blower. I clear a small path by my pool that gets me to my shed and I usually run a shovels width along the edge of the springs but I got lazy and just took my blower out there straight off and hit the last one. Thankfully no damage to the cover.

Since the cover was a bit loose, I looked underneath it and found that the water was almost up to the coping. I had to break away a little ice to get my submersible pump in there, but I pumped out a few inches to give me room for the spring rains. While in there, I also checked the chlorine. There was still some there, about 3ppm, so I’ll need to get pumping and chlorinating as soon as any risk of freezing is past. Probably by the end of March.

All in all, a good day to tinker with the pool and a few other outdoor chores.

M,

Are we talking about Amazon reviews???

I'm a fool for my RJ-60+...I would (will) buy again when necessary. Has given me GREAT service.
