    How long should a Maytronics "Robot" last

    So frustrated, but figured I would get some feedback as maybe I have unrealistic expectations....or I brought the wrong Brand Robot. I leave in NE, so pool season is 5 months. I am starting year 3 with my Nautius Robot. The day I bought it, it already needed a warranty repair around the power...

    Biofilm on Fiberglass Walls ?

    So...I happened to have my original pool builder over for the first time since finished. He was amazed on how clear the water was, but then I happened to ask him what is the slight "variation in color" on the fiberglass walls. My pool has always been maintained via TFP and my chems have been...

    pH - can't keep it up, should I worry?

    so for the life of my pool, IG - Fiberglass, my pH would hover around 7.6-7.8. I think I used acid once or twice I its life. NOW, I can't seem to keep my pH above 7.2 - 7.3 no matter what I do. I've added enough Borates to where my pH should be above 8, but it still (even with new reagent)...

    Short SLAM or wait till I get back from work trip?

    So I made a mistake and let my FC drop for a few days below the minimum...and now I have a SLIGHT Algae issue, so slight that the water is super clear, but it is not up to my TFP standards, so did a OCLT and lost 1.5PPM, time to SLAM. HOWEVER today I have exactly 10 hours before I have to leave...

    Any Reason I should not run CYA of 70 with Stenner Pump

    I tried searching and could not find a 100% surefire answer...so here I go. Been using TFP method for quite a few years and super loyal to it, and I have not had a green pool in years (well ever, other than wacked out issue a few years ago) Anyways....since then I have my Stenner dialed in to...

    Is this plug ok ?

    So normally my PB winterized for me, but this year he has not been available, plus I would love to save the $$ Only question I really have left is the plugs for the skimmers, I seem to have 2 kinds...the big black rubber plugs, and then these. These look like they were used for the "return"...

    Make sure I am thiking straight about pH - 7.8 TA 110

    Water is crystal clear, but my pH like to peg round 7.8 I can lower, but it raises back up....I do have a slide and a 5 year old that swims a ton (2 hours a night) No eye irritation and water is lovely. Should I worry about anything, or is this totally ok. If I had acid, the pH slowly goes...

    If I SWAP Filters - sand to something else, how can I predict pressure change on low?

    Ok, tough title... I had an issue with my setup and my pump/filter supplying enough "back pressure" to allow my heat pump to run on low. The PB basically said he adjusted as low as possible, I finally put the smallest return jets on the three returns and I got enough "back pressure" to run my...

    Dolphin Nautilis and Fiberglass pools and wall climbing

    so got my new robot (named mr. button by our son) into the pool for the first time. only issue is it NEVER makes it up a wall...not even close. somewhere I read (but can't find it now) that there are rollers made exclusively for FG pools, and the combo roller it comes with will NEVER climb a...

    Robots and FC Level ?

    So I could not find a thread exactly asking this, if I screwed up just let me know and lock this. My new Dolphin came today and on it was a BIG WARNING not to run in FC above 4 PPM ? REALLY ? I assume Maytronics has no clue on CYA vs FC levels...thus this warning might be for pools with no...

    Dolphin Nautilus damaging walls ?

    So I was about to pull the plug on this, but then I read some reviews on Amazon that the "black" housing causes black rubber marks on the walls when it bumps into them. Has anyone who has one (or experience using them) had this problem ? I have a fiberglass pool, and I know that the walls can...

    Round pressure gauge vs. square back

    Hopefully this makes sense... My Waterco pump has a "rounded indentation" for a gauge and a o-ring. All the gauges I find have SQUARE ends and when I tighten it the o-ring does not seat. This has leaked since day one and I would like to fix. Any ideas where I can find a rounded back end to...

    New(ish) Sand Filter still spewing junk after multiple attemps from Pool Builder

    Ok....so 1 1/2 years in I am still fighting my pool builder with the performance of my new filter. From day one dirt always poured through the sand back into the pool...I started with "glass" media and ultimately replaced with "sand". With the glass, the water NEVER filtered, and lots of...

    Will this pump/filter combo work?

    So if you see in my signature...I have a 1 HP (uprated to 1.33 HP) pump with a 30" (soon to be converted back to sand) filter. I am fighting with ECOsmarte / Pool Builder and now they are claiming my pump is under powered and will NEVER EVER work in a sand filter as large as I have. Of course...

    Modified SLAM due to heavy travel schedule

    Ok, so I will start by saying I know this is WRONG but I have no choice. Due to my travel I am never home more than 2 days in a row. I CHART by chems religiously and use the Stenner to keep my pool perfect. UNTIL THIS YEAR - opened pool in cold, SLAMed it - perfectly clear and passed OCLT on...

    1 Micron Magic Dirt not filtering - or am I just crazy

    So I won't go into it, but I am still fighting some filter issues from my original build...in the meantime I figured I would try a 1 micron "slime bag" over the returns to see just how much dirt is actually being missed by the filter. Well, guess what...the bag is catching some of the dirt, but...

    PB didn't listen - Phos Free will it cause damage

    I really wish PB would listen... Ok long story, but I will avoid all that...I have an issue with my filter not filtering and my PB insists I need PHOSFree to help my filter. I tell him NO NO NO NO, but guess what he does. Adds nearly a gallon of it to my skimmer. He says it is supposed to...

    I don't THINK I need to SLAM but maybe you think I should help ?
