When I get the algae gone, how do I best return the FC level to around 4-5? Pump out water and replace?
What if I want to do if faster?JasonLion said:The FC level will go down by it's self. It may take a couple of days.

I last worked on the pool on 5/15, it is now 5/26. It has rained for the last 3 days. The pool is clear but has debris (mustard algae?) in the corners and the wrinkles of the liner (the usual places that it shows up). I had turned the SWG off while the FC was at Mustard Algae shock levels and forgot to turn it back on until today. I now have it in "72 hr BOOST" mode. I sampled this morning and got these results...
FC - .5
CC - .5
TC - 1.0
CYA - 50
pH - 8.2+
TA - 240 (built an aerator and it's been running for the last 10 days)
I'm gonna go vac to waste (water level is high from the rain anyway) and add some CYA afterward. I hope that the SWG is working properly now that I reprogrammed it. We'll see.
Add in to this ridiculous scenario that we're leaving for the Dominican Republic on Saturday for a week and I don't want to come back to a swamp (again).
Have I mentioned that I hate this pool? :grrrr:
EDIT: I tested my water straight from the tap and the TA is 330! No wonder I can't get it down!
SinistrV6 said:A couple of questions:
1. When testing for TA is the test completed when the solution turns red and stays red? It "flashes" to red a good bit earlier but won't stay red.
2. Algae (from my reading) thrives when circulation is inadequate. I'm wondering if my pool has a large enough pump and/or enough returns to achieve adequate water movement. The pump is 1hp and there are 3 returns (4 if you count the port for the Polaris). Because it's L-Shaped there are some significant "dead zones".
JasonLion said:You need to get your PH down, especially if you are going away.
SWG pools are low maintenance due to the automatic generation of chlorine, but I doubt they do nothing to the pool since most SWG pools will rise in pH over time. If they don't add acid, then their pH can get pretty high. If they had plaster pools, they'd probably have scaling, but because they have vinyl pools with lower Calcium Hardness (CH) all they have is high pH. That's not great on the eyes.SinistrV6 said:BTW, I have 4 neighbors who all have vinyl IG pools w/SWGs. Obviously, they use the same fill water that I do. I'm gonna sample one of their pools when I get back and see what their water "looks" like. They do almost NOTHING to their pools year round. My one buddy says he "throws about 4 of those 1# bags of shock in it when he first opens it and never touches it again!
