+1. It's turning the long sand filter cycle into a fast an efficient one.
Well I only have to backwash with the DE. Without it- didn’t need to at allIf you're having to backwash often I would say it's working getting whatever crud is there out.
I know that's because it's catching more of the yuckWell I only have to backwash with the DE. Without it- didn’t need to at all
Mine is Salt water generator...so I only use liquid chlorine (Sodium Hypochlorite 12%) for shocking/etc...I dumped 1.5 gallons on it the moment I turned on the pump and started brushing away (fished out all the leaves and debris from the bottom first)...a couple of days and the pool was crystal clear (running pump/filter 24 hours at 90%)...had to back wash the sand filter a couple of times...I started the opening process in April....Okay I just purchased the kit. Currently filling up the pool (it’s not at skimmer level yet). So when I’m able to actually turn the pool on, while I wait for this test kit. Just throw in up to 5ppm of chlorine? Tabs? Powder?
It is possible if the filter is not too dirty...I usually go by the head pressure on the pump before I backwash....when the pump hits 8-10 PSI above its normal pressure, that is when I backwashIs it normal that I only have to backwash for like 30 seconds for it to be clear? I read 2/3 mins but mine gets clear much quicker. Don’t want to run the 3 mins just to drain the water
FYI -- TFPC guideline is going by 25% over the clean filter pressure.when the pump hits 8-10 PSI above its normal pressure, that is when I backwash
It takes as long as it takes to clear. I believe the standard recommendation is assuming a normal filter cycle with lots of time to get the gunk settled deep in the filter.Is it normal that I only have to backwash for like 30 seconds for it to be clear
In general yes but a lot of us have swcg's to maintain chlorineThird day in a row passing the OCLT. still slamming bc pool is still cloudy. After it gets all clear. How do you maintain the chlorine if you don’t use tabs? You measure the FC every day and add liquid chlorine?
Uh yeah I don’t see myself taking levels everyday lol maybe will need to invest in a SWCG soonIn general yes but a lot of us have swcg's to maintain chlorine
I used to do it manual for years. It's quick & easy. I would do when I got up in the morning & again in the evening. Less than 5 min each time.Uh yeah I don’t see myself taking levels everyday lol maybe will need to invest in a SWCG soon
Awesome. So the algae is dead and it's now a mechanical / filter battle instead of a chemistry battle. You keep the FC up because brushing may expose new layers of algae on the walls, previously protected by the biofilm it grows, but the FC should be much easier to maintain at this point.Third day in a row passing the OCLT. still slamming bc pool is still cloudy
After you get to know how your pool responds to that point in the season, you can double dose every other day.You measure the FC every day and add liquid chlorine
Great Ty for the advice. Something about doing it myself makes me feel more accomplished- I can’t imagine if pool company opened. They’d just throw in 10 gallons of chlorine on day one which would probably turn to 0 PPM after a few hours lolAwesome.

No need to OCLT until the water is clear, unless you're curious and just want to. If you fail any of the 3 exit criteria, the SLAM continues. Nothing is gained by failing 2 criteria.

Thanks for the heads up !FYI -- TFPC guideline is going by 25% over the clean filter pressure.
Minimum, plus the expected daily loss from UV at that point in the season (based upon recent tests), *plus* some wiggle room.my recommended chlorine PPM?
