We're renting a house that has an 18x36 in ground pool that is approximately 25,000 gallons. It's a weird pool. When we first moved in to the house I could see the bottom. Half the pool is shallow and then the deep end looks like a chinese food takeout container. Very deep in the center of the deep end with sloping sides up to the walls. We have a Pentair Tagelus 60D sand filter with a hayward 1 hp pump.
Anyways, I've read pool school, have a Taylor k-2006 on the way, and have a 6 way test kit as well as strips. Decided to start shocking the pool with bleach and managed to turn my green swamp in to a cloudy blue. Kept it the chlorine in the very vibrant yellow color as best I could for 4 days and didn't see any improvement with the water. Decided to check the sand filter and saw that the sand was about 8 inches low so put in two bags of filter sand to bring it back up to proper freeboard. Adding sand took me about 3 days to finally get done. Things got busy around here.
As of now I'm wondering how to proceed. I put 3 tri-chlor tablets in a floater a few days ago to add some chlorine and some CYA since it seems very low. Here's my numbers, and some pictures.
What can I do until my full test kit is delivered next week?
Cl: somwhere between 0 and 1
CYA: Very slightly cloudy, but can clearly see the dot at the top of my test tube which goes to 30.
