You could try a service like Instacart. They will deliver groceries and other items from grocery stores and Costco type places. There is a fee. They also are not obligated to charge the same price as the store. I checked on the 3 gallons of bleach from Costco and it was $2 more expensive...

For a few bucks at Home Depot you could rig up some fittings to your hose that would let you jam a long length of 3/8" poly tubing thru the drain and blast out the debris. Sent from my Nexus 6P using Tapatalk

My straight tap water has significant CC in it. I believe it's one way the municipality chlorinates the water. If I dump a completed test with zero CC into the sink with running water, it turns pink immediately.

For FC consideration only, I'd probably go up to shock and walk away. Whether or not I'd float a puck or two would depend on the stability of my pH. If pH rising fast beyond where I want it, I'd add some pucks to keep that in check.

It's OK to go below TA of 70 if you keep an eye on the CSI. My pool's pH rise slows way down when I keep the TA in the 50-60 range. There are lots of examples of this throughout the forum.

It is indeed much less trouble during the winter here in AZ. But don't get lulled into complacency like I did last year. In late winter/early spring last year I found myself with an algae bloom sure to the longer and warmer days consuming my chlorine faster than deep winter. Sent from my...

My fill water has a TA over 200 - so there is always upward pressure on my TA and pH. My pH rise slows way down when I keep the TA in the 50-60 range. It won't really go over 7.8 or 7.9 unless the TA goes over 60. And it's a slow rise (4-5 days) from 7.5 to 7.8. If I were you, I'd keep...

Sniffing should be reserved for flowers and glue.

It takes way longer if you wait for it to go all the way back up to 7.8. The pH rise from 7.2 (or 7.0) to 7.5 is much faster than the rise from 7.5 to 7.8. You can save your time by re-dosing the acid when it gets to 7.4/7.5.

Yeah - you're probably right. Like I said - I worry about some things less than I probably should and possibly at my own peril. Would you water a vegetable garden with purple pipe water?

Non-potable doesn't necessarily mean it's dangerous. Lots of people use lake or trucked in water to fill their pools and those sources would likely be considered non-potable. I'd have no problem using it provided it was tested and acceptable for stuff I couldn't easily remove like metals &...

There could also be something organic in the water consuming the FC. Although with no CYA, 6ppm FC would be like a nuclear holocaust. When my CYA unexpectedly dropped to under 20, I was losing 5-6 PPM FC during the day. Granted that was in the brutal sun of June or July. I would go to...

TFTestkits.net ships fast. Order today and I bet you have it mid week up the east coast.

To be fair, the OP did present it as a theory question. Could be an interesting topic to discuss even if there's no practical application. Maybe it should be over in the chem 201 section.

How is the efficacy of chlorine changed with temperature? I believe chlorine is more effective at higher temperatures. Might be a wash.
