    Upgrading from cartridge to sand filter

    I thought I replied to this but I'm not seeing it. The OCLT was < 1. The CC is 0. I got the stabilizer up to 50 and the chlorine level is holding at the SLAM target. I've been running the robot a few times a day. The pool is getting clearer and clearer by the day. After reading the wiki...

    Upgrading from cartridge to sand filter

    This is what my dirty filters look like that drastically reduce flow and cause pressure to increase. Pressure after cleaning filters. Pressure a couple hours later Filter basket. Its always had about this many bubbles since we bought the house. May be a little hard to see but it wouldn't...

    Upgrading from cartridge to sand filter

    Our filters don't get near that dirty and the pressure spikes from clean to dirty, if I recall 30 PSI, and there is noticeably reduced flow at the jets. In the filter basket near the top there have always been 1 or 2 water bubbles at the very top. When the filters are clean the system works...

    Upgrading from cartridge to sand filter

    I'm wanting a sand filter so I can back flush rather than take the filter apart and clean each cartridge. When we first open the pool we are having to clean the cartridges several times a day due to the amount of dirt that gets in the pool. It takes 30+ minutes by the time you disassemble...

    Upgrading from cartridge to sand filter

    I'm wanting to upgrade from a CV340 cartridge filter to a sand filter. My pool is ~35,000 gallons. My pump: Pentair Whisper Flow 011775 K63CXEBK THP 2.6 As I understand my pump is 120 GPM and the CV340 is rated for 140 GPM. I think I've properly sized a Hayward W3S10T2 given the volume of...

    FC and CC keep changing places in test and PH advice.

    I might be nearing the end of the Ammonia after 43 gallons of 12.5% liquid pool shock. The OCLT for last night to this morning was 2.6 to 2.0. CC was measuring at 0.2 most the day and was 0 tonight. For the first time ever I tested, added chlorine, waited 1 hour, tested and the FC rose by...

    FC and CC keep changing places in test and PH advice.

    Thanks!!! Somehow I missed the Ammonia article in all the reading I did. I would agree with you based on that article it generally sounds like Ammonia. A couple days ago I added 242 oz of Bleach 12.5% at 9 PM. The next morning it measured 2.4 FC. While not great it did hold chlorine...

    FC and CC keep changing places in test and PH advice.

    Hi, New pool owner as of July last year. Like everyone we wasted quite a bit of money at the pool store and using phosphate remover. Also we started off with test strips. I found TroubleFree part way through the season. Near the end of the season I started a SLAM as we've never really been...
