    PENTAIRE INTELLIFLOW 3H, 230 VOLT PUMP OCCASIONALLY TRIPPING BREAKER

    A little over 3 years ago my intire outside electrical panal blew up, taking my pump with it. I had a complete replacement and rebuild of my panel. After that I had the new Pentair pump installed. About 2 months ago I started noticing that my pump was occasionally not turning on as per...

    Ph vs CSI

    I have always had a proble with rising pH but have been able to control with additions of muratic acid. However readings today and 3 days ago have me stumped. 3 days ago pH was 8.8, TA 75, CH 850, Salt 4000, Bor 50, temp 47, CSI 0.00. In order to get pH down somewhat I added 24 oz acid...

    Members by location?

    Is there any way to search for members by location? I live in San Antonio TX and water is supplied by San Antonio Water System (SAWS). My supply water has extremely high TA (220) according 2 water tests this morning with Taylor drop kit. I am wondering how anyone else in the area might be...

    Question about partial drain and refill to lower high CH

    I feel I need to do a partial drain & refill in my salt pool in order to reduce my 750 CH. I am planning to drain about 1/3 of my pool and replace with 170 CH city water. That should give me a new reading of approx 557. Is that worth the cost and effort? My main concern is also my TA level...

    New Pentair VS Pump

    I replaced my old single speed pump with a Pentair VSF 011056 this past week due to a power surge which destroyed the old pump. I used to think that my water was absolutely clear but after just 3 days I realize that the VSF has taken clarity to a whole new level. I am a little confused about...

    Correct wiring for SWG with VS pump for safety

    I will be switching from a 2 speed pump to a Pentair VSF-011056 later this week. I also have an already installed Hayward AquaRite Pro ARQ9 SWG. I have a few questions. 1. What flow rate is required to have the SWG produce chlorine? 2. Will chlorine generation be the same at low flows as it...

    Brown spots on pool floor

    Recently these stains have been showing up on my pool floor. They are in several areas, but all are directly under overhanging Live Oak tree limbs. Brushing and Prowler cleaner are of no help in getting rid of them. Over the span of 2 or 3 days they do fade and then disappear without the...

    Ph testing with Taylor SpeedStir

    I just received a SpeedStir and noticed that there is no 44ml level on the enclosed vial, but in order to test with Taylor K-2006C a 44ml sample is required. There is no alternative testing method for smaller samples as there is for CH and TA. Do I need to use the manual Ph test included with...

    Alternative to DE

    Moved from here. @Richard320 Are you still using Cellulose Fiber instead of DE? Just wondering if you're still happy with it. I am considering trying it myself. Thanks

    Pool Blaster Catfish

    I have an IG plaster pool with an attached spa. I have always had a problem keeping the stairs and spa floor clean due to leaves and blowing dust. Has anyone had any experience with the Pool Blaster Catfish battery operated vac, or any other similar items...

    Algae bloom and draining of pool

    Due to a recent illness, I had to be away from home and my pool for well over a month. I returned home earlier this week to a disaster. The guy I had looking after the pool apparently did nothing. I have very bad algae growth on the walls, water is perfectly clear due to pump reuuning daily...

    New pump not running as well as old pump

    I just replaced a 12 year old Speck 2 speed 1 1/2 hp pump with a Whisperflow 2 speed 2 hp pump, and it seems the Speck pump was better. Here are my observations since the pump replacement: 1. Priming takes a lot longer. 2. Filter pressure with new, clean 100 sq ft cartridge filter is now about...

    Resurface Options

    I have a 15 year old, 10,000 gal inground gunite/plaster pool that will need resurfacing this fall or winter. Waterline tile is in very good shape, so just the plastered areas will need attention. I have naturally been thinking about having it replastered but yesterday I received a mailing...
