    Did I put in too much muritic acid at once?

    This evening my PH tested at 8. To bring it down to 7.5 I added about 5 cups of MA to the pool in front of the skimmer and will run the system all night. Did I over do it? Will it be safe to swim in tomorrow? MA is scary stuff and I just want to make sure I did this right.

    Current numbers are:

    CH- 204

    20,000 gallon, SWG Fiberglass pool.

    Go do another pH test once the pool has circulated for about half hour. Then you'll know what those 5 cups did. It should be fine though because 5 cups of 31% MA would only lower pH by .58, and TA by 9.4. If it didn't do that, your volume might need to be re-calculated.

    Year 3 BBB -15' x 48" Intex Metal Frame - Was using (2) 1000gph Intex cartridge filters (see Full time pumping Intex). 2012, converted to 1600gph and sand filter+SWG = Sand filter love affair!
    Don't waste time and energy looking for a better value on test kits, the TF100 is the best deal around. I did the looking and spent the extra money, but you don't have to make the same mistake. Just go here: TFTestkits. I use Pool Calculator for min/max, and shocking chlorine levels.
