As I understand it these robots have a drive motor and a suction motor, but I can’t seem to find those parts separately and instead have only seen a “motor unit” part for purchase. Is it safe to assume both motors are included in the unit? My robot has had issues for a while now that we suspect...

I think I already confirmed by searching I'm just out of luck here, but two of the three Microbrites in my pool are now unable to emit red light - there is a very, very dim red light in one of them, nothing in the other. So if the dial is set to white, blue or green they all work - set it to red...

I'm relaying a message from a family friend who I don't want to see taken advantage of, but without going into the pool service business as a side job I can't run over there multiple times a week to take things into my own hands either. Long story short her pool is 23 years old and she is...

Noticed this morning my Hayward Aqua Rite 900 has no power, aka no LCD screen or LED light indicator. Did the basic troubleshooting, the board is getting 243V and the 20A fuse is good. I did find this piece on the control board marked “R18” that looks a little toasty. We’ve had some bad...

Trying to determine if my eyes are playing tricks, if this is a chemistry issue, or if this is just the way it is and I'm going to have to accept it. We've had our pool completed for about 2.5 years now, and this winter I started to notice the first area of discoloration of the liner. I get...

Dad and I installed a new Polaris PB4-60 pump at his equipment pad less than a year ago; in the past few weeks, he's had a couple instances of the pump failing to power on, only to come on just fine perhaps the next day or in one case not until three or four days later. I know the motor isn't...

I'm probably not alone when I say it's Dang hot right now. Here in southern Alabama we've been in the upper 90s all week, with triple digits 3 days in the next 7 day forecast. My pool is 94 degrees. Now don't get me wrong, when the heat index is 110+ even 94 feels good but I could go for some...

After a good leaf drop, our robot will eventually get all the leaves off the bottom but we might have to run him 5 or 6 or more times to get them all. Given that the water current tends to gather the leaves in a couple of spots it feels like a better first step would be to scoop what I can scoop...

The basic gist of my pump schedule is 2 hours in the morning at 2300RPM, then 10 hours at 1400, followed by another 2 hours at 2300 before shutting off until the cycle starts again the next day. During the first 2 hours at 2300, no whining. 10 hours at 1400, no whine. But some days - not every...

My siblings and I are in talks about a group gift for dad, and I suggested a replacement Polaris 280. I swear he's been patching his together with scraps for 20 years, and as much as I hate to take away his hobby I think he'd appreciate a fresh start. We actually just replaced his booster pump a...

Followed this guide to add DE to my filter through the skimmer, which says typically plan to add 1-2 cups of DE. Read some other posts where people have only needed to add as little as 1/2 or 3/4 cup. I stopped at 4 cups today and while my filter pressure had moved, it still had not increased by...

Silly question, but I'll ask it anyway. Is there any reason you couldn't scoop up a 5 gallon bucket of pool water and put it in a dark spot for 6 or 10 hours to simulate an OCLT, testing it at the beginning and end of that period? Like maybe you really think you'll need to start a slam but don't...

Very random question, but in the midst of my SLAM I've noticed the same thing occur two times and I want to know if it's "normal" or I'm off in my testing. After performing an FAS-DPD test to determine FC, adding the necessary drops of R-0871 until the water in the tube is clear (followed by 5...

My story sounds pretty familiar to that of @C3Cl3N3O3 in this thread, except for the whole opening the pool bit. History of my test results going back a month: 1 month ago 26 days ago 20 days ago 16 days ago 11 days ago 7 days ago 3 days ago FC 5.5 5.5 6.0 5.5 6.0 5.0 4.5 CC 0.5 0.5...

Should be easy, is the time set in the bot itself or the app or is it supposed to update from the internet? Anyone else had theirs not update after springing forward last weekend? Nowhere in the app do I see a current time but I started a 2 hour cycle at 6:02, tells me it will finish cleaning...

So my S300i has 4 cleaning modes - Regular, Floor Only, Fast Mode Ultra Clean, and Water Line. Regular "Cleans the floor, walls and waterline" and Ultra Clean "Cleans the floor, walls and waterline extra carefully." What does that even mean? They are both 2.0 Hr runtimes, so it's not even like...

Edit: scope of the thread has changed a bit, originally was planning to try and orientate the square lid but have changed plans to swap to a round lid. Maybe next week is finally when we get our paver coping and decking installed. Which gives me a few days still to figure out if my skimmer lid...

Obviously it goes without saying that higher salt concentration lends to a higher likelihood for corrosion, but likely still very little risk when in the "acceptable range" - but with that said, is there any advantage to being at the upper end of said range? Understanding that the ideal range is...

We're closing in on having our coping and decking completed, at which time we're also working up a drainage plan. The plan is to configure what is essentially a 40 sqft/80 cuft (600 gallon) gravel drain field out in the yard, and into that field would be the pool overflow, a channel drain from...

As a general rule, how tight should eyeball return fittings be? I have one that due to how close it is to the surface of the pool I can visually see that water is escaping around the edges of the collar, and can confirm that by feeling with my hand that there is a decent amount of water (and air...

Just pulled the skimmer basket and after dumping it I walked back over just in time to watch a leaf enter the opening and get slurped right down the skimmer drain. No big deal I thought, I’ll get it out of the pump basket in a sec...only it isn’t there yet, I don’t think. There are some small...

First, no I’m not talking about the strainer basket lid. But the control panel itself has a flip up cover and I can’t get the dang thing to close back down over the face of the panel. I don’t feel there’s any special tricks but I figured I’d check here before sending an inquiry to Pentair. I...

Wanted to install the app and do whatever I need to do to setup an account, etc ahead of unboxing my Dolphin for my pool that isn't done yet, but which app do I need? I searched the (iOS) app store for Maytronics and I see MyDolphin Plus, MyDolphin, DolphinTech, DolphinTech Plus all by...

Pretty rookie question but couldn't find an obvious answer while searching - I plan to order the TF100 for sure, but curious about which add-ons as I know some tests are more or less critical depending on your pool's construction. In my case we're going vinyl, so are there tests I want to make...

Hello all, I just finished reading the TFPC for Beginners thread (TFPC for Beginners) which is extremely educational but also has a lot of "this helps with plaster, this doesn't apply if you have SWG" and such. I'm open to learning as much as I can, but also don't want to go down a rabbit hole...

We're slated to start construction in November of an in ground, freeform vinyl liner pool with polymer walls. The plan is to do a paver decking and coping which the PB does not do on his own, we are subbing that out ourselves to the contractor we used for our patio. Would there be any harm - or...

Apologies in advance in that I'm cross-posting a bit, I asked for equipment suggestion in my other thread but thought I would try in this sub-forum as well as I'm specifically trying to settle on a pump. The builder's initial proposal includes a 3/4 HP Hayward MaxFlo XL. The pool will be about...

Pardon my ignorance - don't have a pool, hoping to have one built this fall/winter, just doing my best to educate myself now. While reading about pool cleaners (pressure vs robot) I also came across several comments suggesting having a dedicated suction line installed to use when vacuuming...

I've read enough to feel confident that I'd rather have a robot than the Polaris 280 that my PB included with his quote, just need to find out if he can offer me the Dolphin or if I would just have to delete the Polaris and buy it on my own. But I do want to make sure the robot option is...

Hey all, we're getting quotes again - last fall we got a few gunite pool quotes and that combined with the other site and patio work we couldn't pull the trigger right away. Instead we did much of the site work to include removal of a few small trees and dozens of shrubs, and tore up and...
