Perhaps I didn't phrase it properly, but that's partly because I don't want to discuss my physical problems openly. The problem is multiple-time-per-day brushing during a slam, not during normal times. But you're right about this likely not being the place to fully consider alternatives to the...

Thanks for your input, but I don't believe you read my OP. I drained my pool last month and the CYA is now close to 45, so I don't wish to lower it further. I then slammed my pool and followed though with mustard shock, though I can no longer brush the pool. I believe I explained that I can no...

Thanks. I should consider SWG. When I considered it previously there was a concern that it stained sandstone in this high-pH ground water. Is this still a consideration? The trichlor tabs do raise CYA, but not very rapidly - I only need to drain water every two or three years.

Dup.

I've definitely had to brush of algae around the spillway to the skimmer basket, and am noticing possible indications of mustard bloom, and I need some alternatives to clearing it up and keeping it clear. Tonight's chemical test showed the following: FC - 8.0 CC - 0 pH = 7.8 (so I added 16oz...

I ordered one in July and, unfortunately, had to return it yesterday. The main problem was the erratic chlorine reading. At first I thought it was a predictable 2 ppm under my FAS test reading; If that had been so I probably would have kept it. Reading off is okay as long as it's predictably...

No, it's just turned off; I expect it's leaking, since the pump's on 24-hours. I was just reading about phosphates and how algae take them up to grow and release them when they die - I wondered if was a recognized phenomenon. Wasn't likely - I searched - but there was always the possibility I...

I wonder if this recommended process has changed since the last time I had mustard algae... Since I go seven years or so between bouts, I'll check the current recommendation the next time. I note, however, that I still don't know why my overnight chlorine drop test showed increases the...

I did two days of FC 20 before starting the four days I mentioned in the original post. I didn't do the OVDT on the first two days, just the MA part.

I'm four days into a chlorine shock for mustard algae and for the last two days the morning Overnight Chlorine Drop Test reading is higher than the previous night. That's never happened to me before - am I missing something? Assuming it isn't normal, I can think of three explanations...

That's a very useful compilation - thanks. I don't test as much as I used to. My pH rises very predictably and my FC drops - if not predictably, at least regularly, so I get by with regular additions of muriatic acid every two days. I've pretty much ignored phosphates, but that will now change...

That's an extremely useful compilation. Thanks. I don't test as much as I used to because we have water in which the pH rises predictably and the FC drops, if not predictably, then regularly, and at 15% of CYA it isn't hard to balance it there. I suppose I need to look harder at phosphates...

Nice to hear. Would it be advantageous to have the sandstone coping sealed every year or so? BTW, I'm brushing and vacuuming sandstone off the bottom, anyway. Then all I have to worry about is SWG shortages...

Thanks. I have considered a SWG and may do that, but I've had long reservations about using it with sandstone coping, given out really hard water.

Thanks. I'm aware liquid chlorine is preferred, but as I mentioned chlorine is unavailable and I'm looking for alternatives. Also as I mentioned, "aeration" is a well-known way to help treat water, and since I don't have a fountain, the sheers must serve, even though they increase the pH...
