    Looking for a My Tech control board ph-111a

    Unfortunately no support from AquaPro. I've found one vendor but they want over $700 for the board... the part is less than $1 but its obsolete. If I can't find the part I'll just buy a new heat pump.

    If anyone has a used PH-111A board please message me. This comes from an AquaPro Pro1300 Heat Pump.

    Looking for a My Tech control board ph-111a

    For my Pool Heat pump... the three digit 7 segment display has gone out (erratic, doesn't show all digits) but otherwise works. I cannot source the display from US or worldwide. This is a 27 pin common anode red display and only 7 leg versions are available today. No NOS available anywhere...

    Diatomaceous Earth catalyst for Yellow Algae?

    Pump in recirc did the trick clearing up the yellow algae. Mustard Algae seems to be gone (or hiding)! Tried cleaning the old sand (6 yrs since new filter) and after two hours gave up. It just wouldn't clear up and had a layer of yellowish shiny stuff on the top that wouldn't come off, even...

    Diatomaceous Earth catalyst for Yellow Algae?

    Still fighting this Mustard Algae beast daily since Aug 8. when I "accidently" let the FC get to 3.5. Maybe the MA is localized in the filter because I can't seem to eradicate it after cleaning everywhere else. Cleaned every source I could find, still there every stinking day. CYA way...

    Diatomaceous Earth catalyst for Yellow Algae?

    Had a long bout with Mustard Algae two weeks ago and finally got it licked but it came back today. Seems it always shows up after a big rain like we had this morning but I added ~6 cups (3.5 lbs) of diatomaceous earth into my sand filter today too and am wondering if that could have poked the...

    Yellow algae won't go away!

    Made it through the weekend without a Mustard Algae breakout (except for some little depression that could be dirt but never showed before). I've let Free Chlorine fall naturally and it's now at 7.5 ppm (losing 0.5/day) cc 0 and pH 7.5. We've had no violent storms for a week so I'm not calling...

    Yellow algae won't go away!

    Not declaring the Mustard Algae over but with y'alls help I can say this skirmish has been won! Another night without MA appearance. FC dropped 0.5 (now 15.5) and zero CC. pH still drops (seems it likes low end of acceptable, 7.2-7.3) so I'm bringing that up to mid-range for now. Even...

    Yellow algae won't go away!

    Mustard algae still pretty much gone today. Maybe a small amount in a slight depression in the bottom of pool. Still Haven’t added any Chlorine in four days. Hardly any change on FC from yesterday (-0.5 ppm, but high at 16) and today was bright sunlight all day. pH up to 7.8 and stable...

    Yellow algae won't go away!

    Small amount of Yellow algae today...maybe a tablespoon size in total in the usual spots. FC now 16.5, CC 0. Other than pH changes I haven't added Chlorine for over 72 hours when I raised FC to 51 (Mustard SLAM with CYA 90). Still working to find the source... Appreciate the support here...

    Yellow algae won't go away!

    The Solar return goes to the Aqua Pro1300 Pool heater (out of view on the side of the house), loops through there before hitting the chlorinator then out to the pool. It doesn't have it's own return. I like the idea of connecting those Solar to/from pipes, opening that black valve and all the...

    Yellow algae won't go away!

    Felipe (flying tivo) how did you get that weir door off the skimmer inlet? I seem to have same Hayward skimmer. Must I take all the screws off and remove the panel? And then what? Pictures?
