shock

Hi, all. Thanks to TFP, opening up my AGP, adjusting and maintaining its chemistry, and closing up shop have been a BREEZE. I'm ridiculously grateful for having found this place. I was looking forward to opening my pool up later this month, but noticed yesterday that my cover cable busted...

I live in south FL so we get a lot of sun and heat of course. I have had the SWG for a couple months and have a real hard time keeping the chlorine level balanced. I have yellow algae now and its spreading, the FC just wont go up or kill it. My CYA is 70 so I think I am good there. Question...

We have an above ground metal frame pool. 12 feet by 33 inches. Just under 2,000 gallons... Steps we followed: 1. We put the pool up. 2. The fire department filled the pool up. 3. Very dark and dirty water. 4. Shocked the pool and have the floating device with chlorine tablet and the arm and...

If I have green algae on the floor of my pool, is it better to vacuum the pool before treating it with CYA, shock, and algecide? Or can something like that only be treated with chemicals and I shouldn't bother vacuming until After the algae goes away with chemical treatment? Thanks!

Had the new inground 18x42 for few weeks now. First party this afternoon, eight year old birthday party. Will be 10 kids swimming. Should I just dump a bottle of this in afterwards to get this back to normal? thank you

Hey all, First post here! My spa specs are below: Hotsprings Flair 335 gallons FC - 15 CC - 0 TA - 70 CH - 200 CYA - 100 pH - 7.5 salt - 1700 ppm Temp - 99° So here is the scenario. I've used the TF pro kit for my SWG pool for a while and it works great. We just got the spa 2 months ago...

For the past year or so, I've done sanitation and shock in my 500 gallon tub with Bromine and MPS mixes. I've recently shifted from MPS to a dichlor-based shock. Since my shocks are typically no more frequent than weekly, should I have any concern of CYA buildup? I don't do any CYA testing...

16x32 above ground pool, all levels perfectly balanced including ph, hardness, chlorine and free chlorine. It’s been crystal clear and beautifully blue all summer. Had almost a week of really high temps and then a lot of storms and rain. Shocked it and kinda at a loss now? Is it the beginning of...

Backstory: Bought house with pool in January. Got it going good with yalls advise. I bought a stenner pump and a drum of chlorine. its been going good. I go on vacation last week, i thought i had plenty chlorine in the stenner but i was wrong. Got home saturday to a very green pool. I poured a...

I’ve been SLAM’ing for close to a week - my second time doing so because I think I jumped the gun a day or two early last time I believe. I have passed the OCLT three mornings in a row. CC is virtually zero. But there is still a small amount of mustard algae every 12 hours or so, when I vacuum...

I have a 20x40 inground vinyl pool. Pool installer was very experienced, put in about 8 years ago. The pool was bonded, I remember seeing the green wire around it before concrete and concrete rebar was wired together as well. He showed me some ohms tests showing ground to pump bolt was...

Guys, out here in Northern California. I have a 30,000 gallon pool and I always put a cover in my pool year round. I only open the cover while using it but if i do not get time to swim I do let it breathe at least once a week in summer and once every 2 weeks in winter. However, I never shock my...

Hi Everyone, I opened my pool last week and got almost all of the visible organics out. I’m on Day 3 of the SLAM. My CYA was high 70, so I needed to get FC up to 28 according to the chart. I’m almost there - FC dropped a little bit after the first day, and I added some additional chlorine...

Hello Everyone, I opened my pool about a week ago and I'm dealing with a semi-cloudy pool (not bad, I can see main drain fine) and the smell of chloramines. I'm in the NE, I have loop lock cover and the pool water is usually disgusting when I open it - that's why I try to start early. I...

My SWG was off for the winter. Last week, my FC level had dropped to 0.5 or 0. I noticed some color in the corners and hoped it was pollen, so I raised the FC to around 10 bc that was all the dichlor I had. finally did a filter clean today and color is back in corners. Think I need to SLAM, but...

As part of weekly or monthly maintenance in a dichlor-then-bleach hot tub, are chlorine shocks necessary (12-13ppm FC, 30ppm CYA)? Or is it just in response to problems (cloudiness, odor, foaming, etc.)? Just getting over some hot tub rash, so I want to make sure I'm dotting every "i".

https://www.amazon.com/gp/product/B002WKO8H2/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 Could I use In The Swim Sodium Di-Chlor Chlorine Granular Pool Shock as an everyday chlorinator? If so, how can I formulate PPM for each ounce? Thank you all.

First time poster here! Background info: we have a 20,000 gallon in the ground pool and have had it working well for 4 summers now. We have a sand filter and a nature 2 cartridge. We have an automatic cover so it’s usually covered unless in use, and it’s used probably every other day. This is...

I have an above ground pool that is 22’ by 52” with a salt water sand filter. I went out of town for a week and when I can home I seen that my pump tripped out and the pool is green. I threw 3 pounds of Trichlor shock and allowed the filter to run continuously for two days and nothing happened...

Hi all, I have just recently set up a 14ft pool and need to add Chlorine as currently the water doesn't have any. I have bought some Shock Chlorine Granules but unfortunately I have been sent Non Chlorine Granules. Can I still use these or do I need actual Chlorine Granules to initially kick...

May I ask where everyone is buying their chlorine from? I know shelf life is important and making sure it is not old after reading threads. I am also wondering if more people just go for the bleach or the actual liquid chlorine? I am just starting to move myself to the TFP way of pool upkeep...

So over the last week I had noticed that the deep end of my 16x32 pool had become a little murky, after testing it i realized the chlorine had gone now to almost nothing. I use a floater with three inch pucks to supply it. I refilled the floater and added a granular cal-hypo to try and quickly...

Opened the pool to find an extreme case of algae build up. Got the water tested and results recommended adding15 oz. of Soda Ash, wait 24 hrs. then add 4 lbs of Hardness Plus every 4 hours for a total of 28 lbs. After 24 hours from final Hardness Plus application measured the water again. Ph...

Perhaps a cornerstone element of Trouble Free Pool Care (TFPC) is understanding the relationship between the chlorine in your pool and the stabilizer you put...
