    is clorox performance bleach the same as clorox regular?

    Thanks to the magic of rounding, there is no difference between 8.25% and 8.3%. Now, if they had claimed 8.30%... Surely the same overpaid marketing genius that rebaptized regular as performance is capable of rounding 8.25 to 8.3.

    Problems with Pentair Rainbow Chlorinator 320

    I used to own one of those (long ago retired). As I recollect, top feed is recommended for 3" pucks and the bottom feed for 1"tabs. Also, there is a flexible flow reducer that is sometimes installed in the inside hole. You may want to remove that if it's there.

    Average Price for Liquid Chlorine ?

    Check out Sahara Pools on US 22 West in Lebanon, about 7 minutes west of Pelican. They had the 5 gallon carboys for $19 last year--I haven't bought yet this year. They seem to turn it over reasonably quickly, too. They have been my supplier since Pelican went to 2.5 gal only.

    Pentair 320 - chlorine tower filling, not dispensing

    There is another hole for the valve towards the top of the tower. You need to screw the valve in there and get a longer hose to connect to the other tap if you use 3" pucks and flow is unsatisfactory. The lower hole is for 1" pucks. The manual explains this. I have no idea why they ship it that...

    How to stop using mineral cartidge in Zodiac Fusion Soft

    If they are like the stand-alone cartridges--of which I am a past victim, they can rupture and release their little metal pellets into your return stream. Leaving a depleted cartridge in there would seem to augment the risk of this happening over time. It happened to me while I was traveling and...

    removing offline puck feeder?

    On my Rainbow 320, I put a threaded cap where the canister screws on and a plug where the hose connects. If I travel for more than one week at a time, I reinstall it. I use the feeder for 1 week and have a friend throw the loaded floater in after 7 days. If I only travel for a week (most years)...

    Pentair Rainbow Auto Feeder Model 320 Question

    Mine is stored in the basement in case I ever need it. I capped the inlet and plugged the outlet (or vice versa) and left the diverter in place so I can reinstall it in minutes if I want to. Been that way for five years.

    Muriatic acid vs. dry acid

    I bet you can find MA if you look in the right place, and for way cheaper than the pool store. Try paint stores, and especially places that sell tile, grout and cement for home construction/renovation. I haven't been to Guam, but I've spent time in South America and Africa and MA is widely used...

    Rainbow 320 Problems

    Is the feed tube connected at the top or the bottom? I believe the bottom connection is for 1" tabs and the top is for pucks. You need a longer tube to connect it at the top but it definitely works better hooked at the top. It may have been installed with a flow reducer in the diverter--a soft...

    Downsides of SWGs - fact or fiction?

    I have considered an SWG for the convenience but I believe the cost implications make it a no-go in my particular case. I have an oversize single speed 1.5 hp pump on a system with all 2" lines and no spa or features. A 4-hour run (two in the AM for skimmer cleaning and two at night at chem...
