    Liquid shock in Maryland

    Anyone have any advice on the best place to get liquid shock in MD. I'm in Howard county. For the past 7 years I've been getting 4 packs of Austin’s Pool Tech Shock (liquid chlorine 12.5%) from the BJs wholesale club in Columbia, but I was there this week and they didn't have it. Maybe too...

    Austin's pool tech shock

    I can't figure out the date code. I have a box from last year with code 1617927MA-1(2) Can someone break that down for me? Thanks!

    Adding Polyquat 60 at higher FC?

    Hello, Getting ready to close here in MD. I shocked and now my FC is at 14, cya is 90, and ph is 7.75. The instructions on the polyquat say to add with FC at 1 to 3ppm, but since the pool is covered and it's cold, that FC is not wanting to drop. I really want to take care of closing the...

    replace existing loop-loc for free form pool

    Hello, My existing loop-loc cover is shot. What would be the best strategy for replacing it? I think it may have come from a local pool supply place, would they have a record of the order so maybe I could get the exact same thing? Or could I send the old one back somehow (it's pretty big 50'...

    Confused by TF100 DPD FC numbers

    I measured the deep end tonight from the edge of the diving board and it was close to 9'. I wasn't able to reach the deepest part. I'll remeasure the shallow when the FC drops enough to get in, but pretty sure it's about 4'. I put length=48, width=18, deep=9 shallow=4 into a calculator I...

    Brushing stains

    Great I will give that a shot. Any words of warning? Is it possible to do damage by brushing too much?

    Confused by TF100 DPD FC numbers

    Def using 10ml. The pool is a funky shape: [attachment=0:37nepr4f]pool_sm.jpg[/attachment:37nepr4f] but it is 48feet long and 18 feet wide at the deep end, and has about a 9 foot deep end and a 4 foot shallow end. Could that be 40K?

    Name that valve

    LOL... Can't really tell any difference if it's closed. Must have something to do with the paramount valves. I've done some testing and it's not the connection between the two paramount valves and it's not the connection between the paramount valves and the filter outlet.

    Confused by TF100 DPD FC numbers

    Hello, I'm just getting started and some of my numbers are not making sense. I've had the pool open for a month and I've had the water clear for about a week. I have the pool at 40K gallons because that's what the pool store said it was. Last night I wanted to shock it so I added 2 gallons...

    Name that valve

    Does anyone know what this valve could be for? There is water running through it when the pump runs. I'm stumped.

    Brushing stains

    Sorry for slacking on the response time. I was pretty sure it was a concrete pool. Can you tell it's vinyl from the pictures? If it is concrete can I wire brush it? All of the surface feels rough. I've had the house for about a year and it wasn't opened last summer. I've used only bleach...

    Brushing stains

    Well I finally got the water clear, and now I can see all the stains! I've been scrubbing these with my standard nylon bristle brush and making no progress. Could these stains be live algae? Should I try a wire bristle brush? Can I damage the surface by brushing too much or too hard? Thanks!

    Shocking story!

    Update: From 6/1 to 6/9 I was shooting for FC of 10 but not multiplying the drops by .5 (Duh!) so while I thought I was at 10 I was really at 5. Ugg. Embarrassing... I've added a total of 15lbs of trichlor and 6 lbs of dichlor (between 6/1 and 6/6) so theoretically my cya should be 34, but...

    Shocking story!

    Thanks all! I'll shoot for 10 FC then and use the dichlor I have, and go to wallmart tomorrow for cya. The ph is now 7, at a FC reading of 7 so I guess I'll leave that alone? I do have 5 lbs of soda ash I could dump in. How long after dumping in a bag of dichlor should I wait before testing...

    Shocking story!

    Long story short, I’ve been trying to shock my 40K gallon green pool that has not been closed with a looploc cover for at least 2 years. I bought the house last summer. Anyway, I figured I’d shock with some diclor since the CYA tested 0, and some 12.5% liquid shock (details are below). But...

    Should I start Saturday morning or wait 'till dark to shock?

    Re: Should I start Saturday morning or wait 'till dark to sh OK - so I dumped in 2 gallons of acid (31.5%) and the PH is now 6.5. Going to try adding baking soda to try to make it go back up.

    Should I start Saturday morning or wait 'till dark to shock?

    Re: Should I start Saturday morning or wait 'till dark to sh ... is that a good TA? Should I try to adjust that? I have a bunch of baking soda... Or should I do the PH first. BTW - thank you VERY much for your help!

    Should I start Saturday morning or wait 'till dark to shock?

    Re: Should I start Saturday morning or wait 'till dark to sh hmmm... maybe I didn't wait long enough for that other stuff to kick in? I'll recheck after I get back from my acid trip. Just measured the TA and it is 50.

    Should I start Saturday morning or wait 'till dark to shock?

    Re: Should I start Saturday morning or wait 'till dark to sh Well I dumped about 8 lb's of the "ph decreaser" in and the ph is still 9.5 (testing with the tft kit it's 8.2, but testing with the hatch kit I have for my well water it's 9.5). Does that stuff go bad? Am I missing something...

    Should I start Saturday morning or wait 'till dark to shock?

    Re: Should I start Saturday morning or wait 'till dark to sh yep - typo. It's sodium bisulfate. If I go through that I guess I'll head to home depot for muriatic acid?

    Should I start Saturday morning or wait 'till dark to shock?

    Re: Should I start Saturday morning or wait 'till dark to sh I had some leaks. Just bought the house last summer and just getting to the point of checking things out now. Roger on the ph. It's 9.5! There were some "ph increaser" granules here. I plan to mix with water and dump in. Have...

    Should I start Saturday morning or wait 'till dark to shock?

    If I can get the water circulating correctly (don't ask), I could start dumping chemicals in this morning. It's going to be hot and sunny here. Is it really bad to start during the day? I'd like to have as much time as possible to monitor and adjust before I have to go back to work on Monday...

    Clorox Bleach Germicidal Concentrated - good for pool?

    So, considering I have no chemicals, my pool was not opened last summer (new to me house), I have a truck, and storage should not be an issue - how many 3-packs of this stuff do you guys think I should buy? I guess the bleach can go bad if it sits around too long?
