Some of you know, I've had to hold off my water change (we're at the 6 month mark) due to some issues with my mom and just not having the time. We were in last nite and noticed the water is more "fizzy" and tho clear, when I tested this morning, the CC is 1.0 so rather than shock it, we're going to make the time to change the water out.
Since we have MPS (not straight MPS, it's Leisure Time Replenish) on hand I'm going to use that with the Nature2 stick to start so I don't have product sitting around to use it up. But now, thanks to all the smart people here, I know a lot more about CYA levels and keeping things in check.
Here's what I plan to do below, can someone gut check me and make sure I don't miss something and there's some questions mixed in below.
1.) Put appropriate amount of Ahh-some in the tub and let it do it's thing
2.) Drain tub (refill and ahh-some again if need be)
QUESTION - I plan to drain using the drain fitting and then to get the final amount out of the tub itself, I was going to hook up my bilge pump to a hose to push the rest out. Does this drain out the lines and such too appropriately and do I need to shut off any valves so I keep water in the pumps and don't have a dry situation on start up? Or is putting the hose down both of the filter holes enough as the manual seems to suggest?
3.) Wipe down tub with appropriate non abrasive cleaner
4.) Refill tub
5.) Our water calcium has been running 110 but when the pool store tested the tap water they said 200 so I'll do what I have to do there, if anything. pH of tap is 7.6 so that should be ok. TA from tap is 70 so there's nothing really to do there but I'll test and adjust as needed. Our metals are almost non existent so nothing to do there.
6.) Put in the Nature2 stick and add some dichlor to start the process of getting CYA up
7.) Add the necessary Borax and MA to get the Borates to 50ppm for a 500 gallon tub
QUESTION - Should we add the Borates at this stage while using MPS/Nature2 or wait until we switch over to bleach?
8.) Let it heat up and enjoy
Am I missing anything?
thanks in advance!
