Re: desired chlorine level when closing pool with solid cove I just want to make sure 6ppm won't hurt solid cover. The pool is closed, but I may contact the cover manufacture, see what they say. thanks

Had the same problem and used PHDown weekly, sometimes every 4-5 days. Then, when I ran out of liquid chlorine I used 10-15 aquachem dual layer tablets then went back to liquid - PH hasn't been a problem since (for remaining month or two until pool closed). My readings were similar to yours...

I've had similar issue with CH readings. If you take your water to a few different Leslie's stores you may get different readings. The guy whose readings were low would stop testing once he saw some particles (metals?) and his results were around 400 if I remember correctly. My TF100 results...

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...

Yes, I think they are ph 3 or less. I would like to know how to make it steady with liquid chlorine. Should I lower my TA a bit? I know, but the question was - how do they manage to hold chlorine level in the pool when they are almost completely dissolved. I had 3ppm today at 8AM and I have 3ppm...

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...

all winterizing plugs are removed. All valves are open. heater bypass valve - will need to look into it. Never used the heater, have no idea how it works. Will need to find a manual to see where this valve is located. thanks for the link on cartridge cleaning. I guess I could run system...

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 have the same issue and keep lowering it almost weekly. My TA is about 90-110, FC 2-5, CYA 30-40 I find it a bit difficult to see the exact PH reading (Taylor K1000), but when it's around 7.8 (against white background) I lower it with 12oz of ph down. Then I test again in a couple hours and...

I wonder how your friend was able to get that exact number. What test kit does he use? CYA is the most difficult test IMO and test results vary depending how you test it. I get 30 when outside with the sun hitting the tube, 40 with the sun hitting my back and the tube is over my shadow, etc.

I do my own testing with TF100 kits, but I'm still confused why Leslie's test results are different. I even had the same water tested in 3 different stores within less than 1hr and I'd count the number of drops myself and I'd check their CYA tube myself and it's different between stores. The TA...

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...

The wind I get here is way too strong. It broke sections of my fence, posts and gate a few times. I don't know if cheap cover with double water bags would do it.

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...

patched with the duct tape both sides of the cover. pool is closed. thanks. P.S. I spoke to Leslies about their cover service. They ship it to some external facility where they evaluate your cover and give you a quote if it's fixable and then ship it back. Shipping is free both ways even if you...

The pipes will be plugged off, but once I turn the pump on next season I'm afraid the the duct tape can get stuck in pipes, unless of course I get it out with the net before I turn on the pump. I know pool stores offer cover repairs, but it costs hundreds.

Not yet. But I'm closing on Monday (if weather permits), so I have to make this decision now

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...

just to make sure I understand this part - I was told that cal hypo, even-though it's not stabilized, will last longer than liquid chlorine in your pool water. Is this 100% wrong? Thanks!

Old thread, but I still wonder if bleach would come out cheaper for shocking. Leslie's sells 50lb and 100lb of 73% Power Powder Pro buckets for about $2 per pound or $1.60 per pound with 20% coupon they email every season. If you have a friend or two you can share 50lb with or you don't mind...

I don't use both all the time, I just didn't expect my chlorine to hold this high for so long. By the way, I find FAS-DPD easier to use and I think it's more accurate. I think I see over 5ppm on OTO while it'll be 3.5ppm on FAS-DPD. I wish there were agents for PH test, because what I see as 7.5...

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...

Thanks for reply. They are called "dual layer". According to Aquachem support I spoke to it does not contain cooper.

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...
