As long as your bucket of disks is tightly sealed (if the pucks inside are loose, you might want to individually or in small bunches put them in ziploc bags and back into the container, just to keep the chlorine from gassing out wherever you store them), you could save them. I find from time to...

Don't mess with that. Just go to a salt water chlorine generator. Eventually you will, so skip the interim agony. I see you're Hayward gear, and they have excellent SWCGs too.

Down here in Houston, Walmart sells 10.5% pool chlorine for around $3.85 when they have it. You might call your local store.

Hi Sarah. I'm Bill. I'm not an alcoholic. I grew up in Baton Rouge, and I miss it. A couple of points. It seems unlikely (but not impossible?) that you have bad 870 powder and/or bad 871 reagent, but the cost to find out is pretty minimal. If you have Amazon Prime, you can order those two...

Just to get a rough idea while you wait for your own reagents, you might suggest your neighbor take a water sample to Leslie's or some nearby pool store. Yeah, not 100% reliable, but now you have no information. Then point your neighbor to the TF-100 test kit, advise getting their top of the...

Again, get your own proper test kit. The top of the line TF100 would be my choice, but whichever you get, you want a SpeedStir for mixing. Re chlorine, all liquid chlorine is not the same. In particular, supermarket bleach may be a bad choice. Percent of chlorine is important and how you...

You ignored the M in SLAM. I'm not sure your wrong about pebble finish being a potential problem. I'm sure it causes faster wear on the brushes of my robot. Less slippery for little feet, though.

A couple of suggestions. One, keep a record of what you spend on the generic items suggested on this site, as they will pretty much always be WAY less than pool store products with names that say what they're for. Something like "Alkalinity UP" is actually sodium bicarbonate (baking soda) that...

+1 on this. I felt like I had it mastered until I went to SWCG and had to run higher CYA (I still don't understand why). At the higher levels the lines on the cylinder are closer and closer together. I'm thinking of using the dilution method where you double the result. There is space...

What Marty said. Full speed is a killer for your electric bill, too. According to Pentair, a 3450rpm pump running at 1/2 speed uses 1/8 as much power. Mine at 3450 draws 2530 watts; at 1300 it uses 111 watts. I run mine 9am to 8pm at 1650 (260w; 25gpm); then 1am to 5am just for the skimming...

I HATE the sight of leaves in the pool. With two Wax Myrtles on the west side of the pool, I have little skinny leaves from these evergreen tree/shrubs all the time. After the freeze, the leaves were all brown and really started dropping (Dropping is a good sign...if the dead leaves stay in...

You can also put tabs in a floater. The tabs add both chlorine and CYA. In your case, you'd still need a bunch of liquid chlorine to get started, though. Keep checking CYA until it reaches your goal.

Might add that with no electricity, you're no longer a SWCG pool, so CYA of 60 is way high. You won't need to add CYA while you're manually chlorinating the pool. Minimum FC while you're using liquid chlorine, for CYA of 60 is 5ppm with recommended 7-9ppm.

I use liquid chlorine also. The Rainbow chlorinator sits idle all the time. When I need to increase CYA, I just put some tabs in a floater and the floater in the spa. Keeping it in the spa keeps it from drifting to a skimmer and over chlorinating there. The spa overflow gets the chlorine to...

I"m back and forth on SWCG. Almost ready to go, I got quotes that seemed way too high. I don't object to a reasonable profit, but I prefer to not personally fund the company owner's retirement fund. Also got a contact from a company in Sugar Land that recommended sticking with liquid...

Thanks, guys. Good point on costs, although, Walmart and HD seem to be holding, and Leslies supplier is in Texas. Pinch-a-Penny sells refills, but you have to buy their 2.5 gallon container first. I'm on the far west side of the Houston metro area, not far from a town with a local feed store...

Leslies has been my liquid chlorine source, as their 12.5% product, after adjusting for chlorine content, has been a better value than Walmart, Home Depot or Lowes. In February, the price of a box of four 1-gallon jugs was $15.99, or $4 a gallon. First of March it jumped to $16.99, still...

I use liquid chlorine solution, usually 12.5%. I also have a bucket of chlorine tabs and a floater. If CYA gets low, as it has done when we've had a lot of rain and overflow goes out into the storm drain, or if it seems to get low at the end of winter, as it's done the last two winters, I'll...

Can you post a full description of your system? All the equipment and devices included. There may be more clues. For example, I get a comments here about my "black magic" equipment: an ozone generator and UV-C appliance. The O3 thing bleeds ozone (and regular air I'm pretty sure) into the...

Skillset, I think we're using the same chlorine from Leslies. It's labeled "Blue Whale Shock Chlorinator" and 12.5%. Generally, where I live it has been the best value in terms of $ per quantity of actual chlorine. At $16.99 for four gallons it's cheaper than Walmart when you take into...

I don't know why the people here smarter than I haven't asked you to do an overnight chlorine loss test. Daytime loss can be from the sun.

First order the TF100 test kit sold here. If available get rush shipping. Do your own tests. Also read the pool school here. Only use liquid chlorine. Powders and tabs are likely to have CYA, and you already have too much of that. I'm assuming you don't have a salt water chlorine...

Supermarkets and Wallyworld are insane here. 7am or 10pm, no difference. I started in to an HEB at 7am today, and checkout lines were all through the store and around the produce department. I left. It's dangerous to hang around crowds of stupid people who are buying the same stuff they buy...

Scot, I didn't pick it up from your posts (could have missed it, though), but you do know that the regular chlorine tabs add CYA to the water, and you've stopped using them...right? You can buy calcium hypochlorite tabs which don't have cya, but they do add a bit of calcium to the water and are...

There is probably a reason these don't exist, but it surely would be convenient if you could have a floater with chlorine and some binder that just evaporates in the pool. Trichlor is bad news. Cal hypo is not as bad but still not good. Either would be OK for short term if the pool is...

I haven't seen the question that is on my mind: How did the cyanuric acid content get so high in your pool? How were you chlorinating before the algae attack? And...are you still running that chlorinating system?

Next time, FWIW some Walmarts have pool chlorine that is 10% for around $3.65. Leslie's here in Houston has 12.5% for $4, a slightly better unit cost than Walmart, but if Walmart is closer to you...
