I found a very old huge bucket of Cal Hypo behind the shed that a friend gave me years ago when she moved into an apartment. The plastic was breaking down and had some cracks so water got into over the years. Several nights ago I brought it to the pool area where I have a flood light for working at night and opened it. My plan was to get the 3" of rock hard substance out to throw away (I guess at the toxic substances drop off in Ft. Worth or our annual city drive up collection). I was then going to put the huge bucket in with the recycling. I chopped, hammered, and used anything I could find to try to break it into pieces with no success. It was basically cemented to the bucket. DH called me in to dinner so I just put the top on loosely planning to go back out to continue. Well......... Dinner was great (homemade beef stew and cornbread - I'd probably starve if he didn't feed me) DH had recorded a great movie. No more work for this girlie.
Next day when I went out a bench had blown over from high winds, tumped the bucket over, and it rolled into the pool. <----------- pun intended Most of it had disolved. Filter and sweep had been running a night for leaf pickup and to dissolve CYA I needed to add from letting out three weeks of rain, 15", and frequent backwashings.
My initial reading of CH was > 3000 but Cl was only ~30 so apparently much of the Cl had broken down and/or leached out. Otherwise Cl would have been much, much higher according to the Pool Calculator.
I proceeded to do lots of draining and refilling. I now have it down to a manageable CH= ~1060 with Cl=8
Doing lots of reading these and other posts I think I'm okay for a few days:
and from this posting.php?mode=quote&f=67&p=30349 (my current numbers below quote)
So what I now have:Originally Posted by JasonLion
CSI = --0.03
temp = 68
Cl = 8
pH = 7.2
TA = 80
CH = ~1060
CYA = a little more than 30 (stocking over jet empty [EDIT) that a.m.; started adding earlier that day before incident) [end EDIT] so it will probably be a little higher in a few days ........... except that I'll be letting more water out.
From reading and the above quote it appears that I will be okay for a day or so until I can get more water taken out and refilled. My pH has been pretty steady before this incident needing only small amounts of MA to keep it at 7.5.
I just converted from ionization a few weeks ago and I've been thrilled with water quality and low maintenance (except for our darned silt/sand from puppies swimming). Thank goodness for my Verro 300 (iRobot version of Aquabot Turbo T-jet) as I can keep the pool swept and water circulated no mater the water level. That's why I got it in the first place in 2007 when I had a monster leak.
Have to get some more cellulose for DE filter tomorrow and more reagents and some more CYA to add back in once I get the CH in acceptable range
So from looking at the discussions and specifically the quote above it looks like my numbers are pretty okay for a short period. One thing I'm not sure about though..... Do I keep the pH a little on the low side like 7.2 or do I need to go lower?
