I have searched and it appears that the flow sensor can cause this to happen. I have noticed that if I decrease to 1300 I now get low flow red light which is new. If I keep flow higher and flow light is green will the cell continue to put out chlorine?

I have not purchased the kit nor acid cleaned my IC40 since putting it into service last year. Pool runs all year but water gets cold so generator is not functioning in the Winter. My output is normally set around 20%. Is it harmful to wait until I see that I must increase output percentage...

One of my skimmers has a leak and it would cost a mint to repair. One skimmer has not been getting the job done so I started to investigate alternatives. It has only been a few weeks but the Solar Breeze is really doing a good job. The concept is elegant, let the sun power the bot. It works...

My spa is plaster, 750 gallons separate from pool filter system. All of a sudden the pH keeps dropping to the 6.9/7 level frequently. I have not been using spa due to the heat. I use chlorine and this has also started to run quite low. TA 90, CH 275. Borates 35 I have been running air pump to...

Yesterday while pump was off I cleaned out my Intelliflow pump basket. I turned of the valves to the skimmer and drain so water would back flow. I forgot to open them afterwords. This morning I saw that my pool wasn't circulating and I discovered the pump off and my error. The pump is working...

There have been threads mentioning this but it is unclear as to how "intelligent" any of the bots are. One thread discussed using the same bot in multiple pools with similar results. Does anyone know how the Maytronics units "learn" and then adapt to an individual pool? They are dropped in at...

I am running an Intelliflow pump at 1500 rpm and pressure is 3. I added DE but stopped after 3 cups when pressure did not rise 1 psi. Should I add more or will the low rpm keep pressure from rising appreciably?

Not talking about wear parts I'm wondering the percentage of Dolphin bots requiring service. What model do/did you have and how many years of use did you get before it needed repair service?

My IC40 is about 5 months old. Yesterday it read low, 2800 add a bag of salt to my 22k gallon pool. I added 20 lbs or less of salt and today it is reading 6600. Using a cheap TDS meter I get 3340. Compared to my pool guy's calibrated meter mine reads about 800 ppm low. I searched threads and...

I can get a new M500 that will be sold as a "demo" by my dealer with a 1 year warranty for $878 plus tax. No cart but I can get one from Ebay for $100 if I need it. Yea or nay at this price? Cart necessary/desirable or not?

I have a Polaris 9500 that is just not getting the job done. It keeps getting stuck on the lower pool step and despite pulling it off it keeps missing major areas of my pool. I'm looking for a robot that can clean my pool, keep from getting stuck on the step, and also have a cartridge instead of...

I have an air entrapment problem with my shallow skimmer. To reduce water loss I decided to plug it besides having skimmer valve off. I noticed that my deep skimmer has 2 2" threaded openings in the bottom but only one is open. The shallow skimmer has 2 2" threaded openings in the bottom...

I have a Polaris 9300xi that is having trouble with getting stuck on my pool steps. I found a used aquabot for under $400 with a 30 day warranty. Am I crazy to consider a robot w/o warranty or would it be worth giving the aquabot a try?

My installer has a new Pentair variable speed pump that arrived with 2 broken bolts. It has full warranty and he ordered replacement bolts. He is willing to sell for $600. What do folks think about this vs paying another $400 for a new pump?

Companies have cracked down on warranty coverage by requiring "professional installation". Would having a licensed electrician connect power qualify? How do we get around being charged $$$ by local companies for the install?

I think that it would be beyond the folks looking after my property to keep the pool algae free. I am debating between pumping out the pool as close to empty as possible or just lowering to usual closing level. Will a covered pool be o.k. with summer heat? Is the lack of light with a cover on...

I purchased a gizmo with attachment to blow out my lines. My skimmer has two openings in the bottom that are eccentrically placed. The gizmo's neck is not long enough to allow it to screw in as the wider part of the gizmo hits a plastic rim that is too close to the return opening. I don't have a...

Newbie looking for cover advice. My pool is small so expense is low on all of these covers. I don't have any trees near the pool or leaf issues. I am leaning towards a mesh cover so that rainwater will refill pool and I would expect that I wouldn't have to deal with pumping water off of the...

Used for a couple of months and now I get flashing lights and no movement. Called Polaris and there is no repair center near me. Regional rep is supposed to arrange repair. They suspect the motor but can't tell w/o diagnostics. There is no way for consumer to troubleshoot. Very disappointing...

I had my pump set to run via controller 0700-2100 daily with no problems. Recently I added a low flow run from 0300-0400. Yesterday and today I found the pump not running in the afternoon. When I pressed the pump button on the controller it started. The time is correct. Every day is indicated by...

My FC is 2.5 and with my oversized SWG and small pool, 4 hours of super chlorination will raise level. I'm wondering what happens if my Intellitouch is set to run pump for two more hours tonight and I have the super chlorination set for 4 hours. Will it run 100% for two hours tonight and then 2...

Finished pool build and we had electrical bonded. The pb ended up putting in fiberglass rail and steps. I had never seen anything but stainless in a pool before. There is no metal in my fiberglass pool to touch. Why would bonding be of benefit?

My new pool has been a challenge and my PB has done almost nothing to help. So far they have been strictly following our contract except for the part where they are supposed to balance the water as stated in the contract. Their balanced parameters are a bit off from the recommendations here but...

What is the upper limit of FC that is o.k. to swim in? Battling algae and shocking like crazy. I'm hopeful that I will pass the FC overnight test tonight and that I can use pool this weekend thus my question. How low must the FC be before it is o.k. to swim. CYA is 75-80.

I'm trying to kill algae. FC measured 40 this a.m. How high can I go before it damages fiberglass pool? Metal steps have not been installed yet. SWG has been used along with bleach to get FC up. Usually SWG is on 5% for 5-7ppm. Can I leave it on 100% for 2 days to maintain high levels w/o...

New pool. Been fighting to get things in balance. There were delays between filling an electrical hookup and then getting chlorine levels up. Everything was looking good until the concrete deck was poured and my robot died. I thought that the Crud in the pool was just dirt and remnants of...

O.K., definite newbie. Pool School states: Lowering TA can take some time, days or even weeks, depending on the amount of aeration you have and how far you need to lower your TA. Many smaller bubbles are better than a few large bubbles. Lowering the PH back to 7.0-7.2 more frequently will also...

Pool school recommends 200-400 ppm above recommended. Intelliclor recommends 3300. Should I leave things as is or trust strips and add salt?

Still gathering data. I have seen references that state that bots with non-foam brushes tend to have trouble climbing to waterline in a fiberglass pool. True or false? Will the Polaris 9300 series, Dolphin/Aquabot types make the grade?

Just wondering because most motors can be repaired. My bot died and the slave motor is no longer available so I've been told that I would need several new motors.
