I've had a pool blaster catfish li for 4 years. I would get really good life on the battery because I didn't use it a lot, mostly to just clean the tracks behind the raised treads on the steps. Recently the battery died and I charged it and put it back in use. Then it ran for maybe 10 minutes...

I've been using it via wifi for over a year. Lately maytronics has asked me to reverify several times. No biggie. But today it said it couldn't connect to the robot. So I figured I'd just switch to Bluetooth mode temporarily. It gave this warning that I would only be able to use Bluetooth but...

After a little over 12 years in use, my temp sensor is finally going out. Water was significantly colder than the intellitouch thought! (verified by a pool thermometer). So I just got a couple of well reviews knockoffs from Amazon (too long to wait for oem, 4x the price locally). Seems like it...

My 13th year with this pool and this is the first time this has happened. I just had the liner replaced two years ago. I contacted the installer who said "Your water level is too high it pushed the beading out" and said it should be "really easy" to put it back and then lower the water. Well, it...

I've decided to replace my 13 year old Mastertemp 250 before it fails completely on me. I got a quote from a local guy for installation and disposal for $4200 (I'm in southeastern Michigan). I can get one for anywhere from 2900 to 3300 which means this guy is charging me $900-$1300 to do this...

My mastertemp 250 has been through 12 summers. I've replaced several parts (control pad, control panel, thermistor, thermal regulator) but I still had a squealing sound at the end of last year when it was heating up (despite a fresh thermal regulator) although it still seemed to be functioning...

I've always wondered...if you add CYA (in particular the liquid kind, since it's "available" so quickly), does it directly "affect" the chlorine level in the water? In other words, will the added CYA "bind" with some of the chlorine and then lower the FC results? Like I said...really dumb...

I have a number of spots, mostly at intersections, where the concrete deck around my pool is chipping and small chunks of concrete are loose, some of which end up in the pool. Any suggestions on what I can try and do to repair these?

Last year I had my liner replaced. I didn't notice it until this year but now I have this sorta weird shadow in the pool. The pictures below are from the year before I had the liner replaced and the next one is last year after it was replaced (May). The last one is a side view I took last year...

I know it's been asked over the years, just thought I'd try again to see if anyone had solved it yet. Technically I think the data is stored in the panel (easytouch, etc), not screenlogic or the adapter. But I'm just guessing...

So I've had mine since I built the pool 12 years ago I think. Yesterday while spraying algae out of it, my wife handed it back to me broken. :cry: The shaft where it goes into the pole just completely broke. Now, it's not beyond me to attempt fixing this...but that's for later. ;) In the...

I noticed a pretty hefty stream of air bubbles coming out of the returns but I also have noticed it's not constant, which leads me to believe it is likely when the SWG is running (not sure how I would actually be able to check that). When I started up this year there was a bad leak on the...

This is a weird one and I've never had happen before... Opened the pool Thursday afternoon - very green, lot of junk in it. Threw a couple of gallons of chlorine in that night. Tested the water yesterday afternoon (just a day later). FC 3.0 CC 0 TA 50 CH 100 CYA 40 But it's still quite cloudy...

My mastertemp 250 learned a new trick this year! :( When it's running, as in I think this is the point where the fan is on, but the heat isn't quite engaged yet, I hear a pretty loud sound from it. And when the heat is on, it's actually worse and more of a squealing. From reading around, it...

I noticed that I'm unable to import anything on Pool Math and the app just crashes (on Android). But, thankfully, restoring my subscription seems to have brought everything over anyway. Is this expected? I notice there is no import option on my computer. Side note: After moving to a new phone...

I have 5.2 build 738.0 Rel. It gets the job done but it's ancient. No longer pulls the weather in (not that I use it, but it's annoying). And of course there is almost no troubleshooting info in it. Like I said...it gets the job done but just curious...

I replaced my liner this year and I've been chasing getting it clean all year. I've entertained a fair amount and don't like to have massive chlorine when doing so which has put a damper in getting ahead of this. I know I have something and it won't die! But here's where I am... My CYA is only...

I cannot keep my pH down at all. I have twice put in acid and lowered it to about 7.2 or 7.4 and it just keeps rising. Initially I had an air intake leak from my pump drain plug that I thought was driving this, but it's still happening after fixing that. It went from 7.4 to 7.8 in a matter of...

I have some deck jets that are split from my returns with an actuator. I use my automation to turn them on every day during pool season for a few minutes, just to make sure the water doesn't get stagnant, etc when they're not in use. We don't actually use them a lot...seemed like a good idea at...

I think this is the right place for this...(please move if not) Anyway, I don't usually pull a lot of air in my system. But this year, I am getting quite a bit. The thing is that none of it is in the pump, where I would see it in the past with various issues. The water stays pinned to the top...

Fired up the system for the first time today and initially the IC40 had power but then at some point pretty early (it was on for a few minutes) the power went out on it. Now, I haven't opened the load center yet because this all happened just before it got dark. This is the original unit...

The liner's out so this is an ideal time. Magic eraser really doesn't work on this part. It's been suggested to just use dawn soap or even toilet bowl cleaner for these white fiberglass steps. Are either of those a good idea? Any other suggestions?

They came out and pulled the liner and we have a relatively significant amount of water coming in by the stairs there (basically under the plastic on the bottom and seems to work it's way to the right). There's a french drain around the pool because they thought this was a problem when building...

I'm about to replace my liner. Should I just drain the pool and leave it closed until the new liner and water is in or should I "open" it and then drain the water. I'm Worried about just shutting it off for 5 days with no water flow without it being sealed up and everything. Or is that not...

I've seen the titular comment a few times and don't understand it. How does one complete a "proper" SLAM if you already have mustard algae? I'm assuming that's what I have because its chewing through chlorine at slam levels like nobody's business. Which brings me back to SLAM says you have to...

Due to a leak in my lines (since repaired) I had to put a lot of water in the pool and it got away from me. Currently doing a SLAM and last night's loss was 11.5! Holy cow! And yet my water is crystal clear too! One thought - also lost my cya in all this. Best to bring it up a little or try to...

My old harbor freight 1/6 hp submersible pump died and so I'm going to replace it with the 1/4 hp oil free submersible pump. The only issue I have with that pump is that discharge is a nicely-odd 1" instead of 1 1/4" or 1 1/2". I can't find any one inch hoses (I can find 1 1/4"...). What can I...

Rented a tent for my daughter's graduation. I had a work call (with my boss' boss) so I wasn't there when they started driving stakes (Friday). Noticed yesterday I probably lost 1.5" of water during the day (with people swimming) and another 1/4" or so overnight (I marked it late last night with...

My Dolphin Supreme M4 has those black fins on one side, but not the other. In honesty, they may have never been there. Or they came off at some point. Does anyone know what they're for and why I would care about them? Or how they would impact it at all if missing on one side?

So I see that lifetime supporters have the "equivalent" of bronze level and I see that all supporters get discounts at Marina Pool, which I assume is via coupon code when you check out there. However, I don't ever recall getting a coupon code for Marina pool, nor can I find one in my inbox...
