    Monitoring CircuPool RJ Plus SWCG

    Two years ago, I installed CircuPool RJ-60 SWCG in my pool. Now the third season is passing without any problems. It’s been a reliable and high-performance device. Last year I replaced my single speed Jandy pump with B&D 3HP VSP and added a Raspberry Pi pool controller of my own design running...

    My new Black&Decker VSP and DIY pool controller

    Earlier this year I bought a Black & Decker 3HP VSP on poolpartstogo.com and have just finished its integration with the pool. The pump is quiet and energy efficient. Here are some numbers: 2200 RPM (priming only) - 2.2A, 530W 1800 RPM (cleaning and/or intensive skimming) - 1.3A, 310W...

    A few comments on my RJ60+

    For the last several days the weather was pretty consistent - 85 to 90 degrees and sunny skies. FC at the end of 8-hours SWG run would be around 5 - 5.5 ppm, in the morning 4.5 - 5 ppm, CYA 70, SWG output 60%. The overnight loss of FC <= 1 ppm. I tried to adjust the output to reach 6 ppm. So I...

    My new Circupool RJ60+ install

    I thought I would share some pictures of my new RJ60+ install - could be helpful to other folks who plan to switch to SWCG. For me it was an opportunity to also fix some unrelated issues: The old stand was small, rotten and placed too close to the equipment pad - there was not enough room to...

    A new sound from my Jandy single-speed pump

    I didn't hear it last season. Kind of a rattling sound. The water flow is good, everything looks normal, but that sound makes me crazy. Asking for an advice - should I detach the motor from the pump and inspect the inside for some debris or broken parts (impeller?). The pump is 4 years old...

    Saving Jandy valves

    I am in the process of switching my pool from Stenner pump to Circupool RJ-60 and trying to save the existing piping and fittings. There is a good place to install the Circupool cell in a vertical configuration, but it involves inserting short sections of 1 1/2'' PVC pipe into 1 1/2 - 2'' Jandy...

    To clean DE filter or not to clean

    Here is my question. I opened the pool in the middle of May. Very clean, transparent water. After a couple of hours I could swim, but since the water was icy cold, I didn't. Two months have passed now, the pressure on the filter stays at 10psi level, the same as right after startup. Now, is...

    Floor returns - asking for advice

    My pool has 3 floor returns which I have kept closed since I bought the house 20 years ago. (And I suspect original owners did the same.) Each time I open the Jandy I am appalled by dirty water coming out of these returns and I quickly close it back. Should I bite the bullet, open the valve and...

    The rate of chlorine decay

    I have 30 ppm of CYA in my pool. Today on a beautiful sunny day I conducted a little experiment. Measured FC at 11am (5ppm) and then at 2:30pm (3.5ppm). The rate of chlorine loss = 1.5 / 3.5 = 0.43 ppm/hour. I’m wondering : would my pool benefit from increasing CYA to 40 ?

    A plumbing question: removing Fusion Inground chlorinator

    I'm finishing my install of a liquid chlorine injector (Stenner pump + Intermatic PE153 timer). I will provide pictures and a description, but for now I have a plumbing question. I need to replace my Fusion Inground chlorinator with a section of a PVC pipe and a T-connector to install the...

    Water chemistry after winterization

    Sorry for the winter subject while the summer has just started... My question is about meshed covers and plaster pools. So we take care of water chemistry during the season, making sure that the pool plaster is safe. Then, at the beginning of October, we lower the water level, blow the lines and...
