So i sent the hub to the pool store to test our salt bc we've drained water off so many times with the rain. It was low BUT he had them run the other chems even tho I just did our testing today. Grrr. They said the phosphorus was high and that was a breeding ground for algae.
Now, we don't have a test for that in our kit but my theory is that if you keep the chlorine where it should be, then you won't have algae. Right or wrong???
AND ofc, they sold him stuff to lower the phosphorus. GRRRR.
salt 2800 (he got 2 bags of salt at store)
Now, I know these are on the low end of recommended and I did the pool calculator to see what to add to put them in at the right level.
