I have about 6ppm right now (cya 50-60) and closing in 18hr with one of those $2,500-3k anchor solid covers. Is that OK? Also, guys who will close my pool may shock it. Last two closings they used non-chlorine shock oxidizer ("GLB 3 part system" and the following year "AquaZone winterizing...

I was out of liquid chlorine last week, so I put 5 tablets in 2 floaters, 4 tablets in 1 floater and 1 in the other. CYA 35 allows it. I had both floaters half open, which kept my chlorine level between at 3-3.5 every single day. We had a couple of rains in the last couple of days (one last...

When I opened my pool and started the pump I realized (about 10-15min later) that I forgot to unplug returns. 2 out of 3 returns plugs were rubber (1 return and vac) and they just shot out. I've been running pool for a couple week now, don't see any issues other then - my pressure used to be 10...

I closed pool in October. When opened at the end of May I had 1-2ppm of chlorine. Is that normal? CYA 30-40. Don't know how much chlorine I had in the pool when it was closed, probably between 2-5. Pool closing kit with chlorine free shock was used right before the cover was put on. Thanks

I had the same pool company close my pool last 2 seasons. When I opened my pool last season it was crystal clear, today I have something that looks like an algae. I tried vacuuming, but it doesn't come off. It's not too much of it, but interestingly it's mostly near main drains and some on...

Quick question. Not really related to pool, but can't find answer elsewhere. Pool is closed for the winter, but I still have 1 gal of 2-3 months old 12.5% Austine pool chlorine that I have no use for. Can I use it in my washer by cutting dose in half? According to washer manual using more...

My cover is pretty heavy and when I remove it, I clean it with the water and pool brush on both sides, let it dry then bend it dozens of times and put it in the cover bag. The cover is about 7yr old, it's not soft and it looks like it's getting worn out where it's been bent. guys who close my...

I have a few holes in my cover and I want to use duct tape to patch it. A couple holes are pretty big, like a quarter slot on soda machines but they are over the deck area, while others are 1-2mm and a couple about 3mm. I know it should probably be patched with the real patch that's made of...

I test my chlorine almost daily, but never seen it this dark before. It's like dark yellow, gold or even light brown. My chlorine level is about 6.5 (using 870, 871), CC 0, CYA 45, PH 7.5, TA 80. I used 8lb baking soda to raise TA to 80-85 last week. Also, the water temperature is probably...

My calcium level was always over 500 and even over 700 with tf test kit. Today it is either 500 or 600 (did the test 4 times and finally out of 0012). Do I have to wait a second or two between drops when I use speedstir? I think I may have done it too fast and may be that can explain why I...

My TA may have been a little low all summer while my PH kept going from 7.4/7.6 to 7.8 within a week (using 2 gal of 12.5% liquid). I kept bringing it down with aquachem "PH down". TF kits had my TA at a 100 while Leslie's and others had it as low as 60. Today my TF reading is around 50-60 (50...

I have an in-ground pool and my water level is at the edge of the cooping due to heavy rain. According to forecast the rain may continue for the next couple of days. should I drain some water? I'm afraid once the water gets over the edge all the dirt around the pool are will end up in my...

Do I need to take care of it now? If so, what products/tools do I use? Thanks.

I tried adjusting PH 3-4 times this season, but it climbs back to 7.8 in a couple of days. My TF kit from last year shows TA at 100. Leslies Taylor 70, 80, 90 (depending on the store). I found a Leslies employee I like and watched her do it twice - both times I counted 7 drops myself. I keep...

Guys who closed my pool mixed shock by blowing the bottom drain. Some chemicals, like PH Down require 2 hours to circulate before you can add other chemicals or test PH level again. I believe some other chemicals require even more time. I don't know if it takes hours to dissolve or mix or...

I have a few holes in my cover. Some are like quarter slots while others are smaller and round. Pool stores sell 3M and Merlin patches for around $50-70 which are about 6x10 and are not self stick. I think it's a bit expensive and I'm sure the same material can be found for a lot less...

I can't find a post which explained which chemicals need to be added and in what order. I remember seeing one, but can't find it anymore. I remember it mentioned the order in which chemicals need to be added and the intervals. I'm about to open my pool and I have FT-100 from last year which...

This pool was built by previous owner about 5-6 years ago. This is going to be my 2nd summer. I have this gap around the whole pool and I believe this gap is getting bigger(or may be I just started paying too much attention to it). Guys who closed my pool last fall said they have never seen a...

I have some cuts on my cover, made by contractors who were doing the siding work on my house. The cuts are not above the pool opening, so the water won't get into my pool through them. I know there are self-adhere patches out there, but will they really work? and if so, which ones would you...

If this is not the right forum for this question, please let me know which one is. According to the manufacture the pump should start pumping water out at 2-3" and stop when the water level is 0.5-1.5" My pump turns on only if the water level is slightly above 4". I tested it with the bucket...

I know this site suggests nothing but liquid chlorine for a number of reasons and that's what I've been using for a couple of months. I've seen these at target for $10-12 and just curious if they are worth getting. I don't think it's a bargain if you compare it to prices in clubs, but you get...

I loose about 2-3pm per day when it's 90-95 F. My cc is 0.5. Does it mean that I'd lose the same 2-3ppm on the same day regardless of the CYA level? According to Chlorine / CYA Chart the difference between minimum FC and target FC is 2ppm (for cya between 30-60). Also, in order to add 3ppm I...

Which parameters are likely to get messed up (other then chlorine) if you test your water 30-60 min after shocking? Today I found some algae in the pool on the lamp, behind the plastic cover. As I removed the plastic cover and wiped off the lamp with the cloth soaked in bleach, the algae ended...

Sorry for double posting, but I'm really concerned with this issue and I don't now who else to turn to. I've purchased the house this year. The pool is about 5yr old. I didn't have any of these dots when I opened the pool, had about a dozen a couple of weeks ago but now I have a lot more of...

I purchased the TF100 10 days ago and fully tested my water 3-4 times since, testing chlorine and ph daily. All the parameters stay the same, even after rain which added ~~3-4 inches, except maybe chlorine level went down by 1ppm. I have not shocked for 2 weeks now (used calcium based shock...

I got this test kit and a spidstir, however I did not use spidstir for this test. Just wanted to get this done as quickly as possible. Please let me know if my test results don't make sense and I need to redo it. Here are my results: K1000 blue box Chlorine > 5 (off the chart. maybe 6 or...

I'm a new in-ground pool owner. First when the pool was opened it had some brown \ green spots. I shocked it with Powder PRO and it all cleared up, but some very light brown spots remain although they get lighter and lighter. Also, it seems like vitamin C removes the brown, but not right away...
