Hi.
I have been fighting algae since I can remember. The water in my pool is almost never sparkling and fully transparent. Is it possible that my sand filter just first do the job properly?
I cleaned it up a few days ago (garden hose from the top) and there was lots of Crud coming out. I had to keep cleaning it for like an hour. I put my arms in and messed the sand as deep as I could reach and I allowed the water from the hose stir it. Even after an hour water wasn't totally clean but was much better.
Since then the pump has been running 24/7 for 3 days while I'm shocking the pool.
What worries me is that the pressure on the filter hasn't changed at all. It started at 12psi after cleaning and 3 days later is still shows 12. I even replaced my old gouge (at the same time I cleaned the filter) as I thought that the old one was faulty (I don't think it ever showed some higher pressure). Water is a bit better and there is no residue at the bottom so it does filter something. I have also added a blue cube to the skimmer that is supposed to glue small particles together to help filtration. After 3 days I can barely see bottom at the deep end.
1. Should the pressure increase after 4 days of shock?
2. Is 12 psi normal sand filter pressure?
3. How much sand should be in the filter? Mine is more than half full. I can reach sand from the top but need to stick my arms up to the elbows to do so.
One more question .
Every time I add chlorine - cal hypo 65% diluted in water - to the pool, the water gets instantly milky white. Is it normal? Does it mean I still have lots of algae? This morning I was able to see the bottom (just), added 500g of cal hypo to get to the shock level (16) and the pool is much more cloudy. Cannot see the bottom any more. Is it normal? Or maybe it reacts with something in the water?
Appreciate any help. I'm dispirited by my never ending battle with the algae.
