Hi everyone. we bought a home with in ground pool and we think we are very close to getting the pool functional.
It's an 18,000 gallon concrete pool.
Last year we completely drained and refilled the pool. We discovered it has a leak in the return line. We got discouraged and left it be for the season. I neglected to cover the pool in the fall and as you can imagine we got lots of leaves in the pool.
This year the water is murky. It's a brown in the deeper part but green/yellow on the ramp where you can see the bottom.
We've scooped all the leaves out we can can locate.
We repaired the return line, replaced the pump and changed the filter laterals and added new sand.
we did a few days of filter/back flush while adding shock, PH up and an alkalinity increase.
we tested with strips and most of or water is now balanced but it's still UGLY!
Saturday we took a water sample to Leslie Pools she said we had algae and recommended Green to Clean while upping PH and shocking.
Sat night we added 5lbs soda ash and let circulate all night. Sunday AM we added Green to clean waited 5 mins and added 2 lbs of shock, 12 hours later we added 2 more lbs of shock and then again Monday AM (24 hours later) we added 2 more lbs. of shock.
Water color had not budged.
Last night we went to another, well respected pool store in our area and had the water retested. He found our Cyanuric Acid to be very high (80) but other levels to be in balance.
He recommended an algeacide with us adding 6lbs of shock (w/o stabilizer) then adding 1/2 a gallon of Splash brand algaecide 5 an hour later. He said we should see TONS of improvement in 8 hours. Much to our disappointment we saw no change this morning.
At this point we're getting desperate. I don't want to keep throwing $$ and chemicals at it.
I have attached some photos that might help illustrate our trouble.
