Our CYA level has built up to about 30 (31.5 by calculation) using Replenish (which is MPS and Dichlor) and a Nature 2 stick. I have some questions before we switch:
1.) Can we yank the Nature 2 stick, throw it in a ziploc and use it at the start of our next fill? We still have Replenish so on our next fill I'd go back to using it to build up the CYA level. The stick only has 1.5 months on it so it seems bad to waste it.
2.) Today's testing gave us the following levels:
pH: 7.0 (but after aerating for 20 minutes it came up to 7.6)
Before we add the borates (29oz Borax and 14oz of 31.45% Muriatic Acid) are our other numbers ok to start? I'm assuming you add the borates and then let that circulate and adjust TA and pH as needed?
Once that's all set, I guess we just keep the FC in the 2-4 range (12ppm for shock level) per the chart and then use Dichlor (we have Spa 56 available) once a month to account for CYA loss.
I'll have to figure out what we do if we're going to be away for more than 2 or 3 days since we don't have anyone nearby to add bleach but I'll cross that bridge if it ever happens once I know a 24 hour loss rate.
thanks in advance!
