Here's the situation. I just purchased:
-Pentair Intelliflo pump
-Hayward low-salt chlorinator
-Hayward sand filter
In order to keep the flow nice and ensure my chlorinator works proper, there's gotta be a certain debit. When my pump works at 1800rpm (info which I got on this forum) I get 1800ppm chlorine levels. Sounds good so far for a 60,000l pool.
However, no matter what I put in the pool, product after product, I've manage to get water chemistry in PERFECT balance according to testing at 3 different stores.
So why is my water still green?
I think it's because my pool needs a good vacuuming, but there always seems to be some sort particules suspended in the water that I can't get rid of. As a result the water is cloudy on its best day.
I spoke about this to the store specialist. She tells me that the pressure in my filter could be too low and not filtering properly. I checked. At 3000rpm, water pressure is 20millibar (is it PSI?). The filter sticker states it needs 10 to operate.
At 1800rpm, the filter is at 7-8millibar/psi.
Could it be that the recycled glass inside the filter cannot be compressed together the way silicate sand can be? Is this why pressure is so low at lower rpms and why my water always seems to keep some particulate matter suspended?
Should I be swapping out glass for sand in my filter?
