Hello all. Your website has been a great help. I haven't worked on a pool since my early teens. I'm working on a rehab in Austin, TX and cleaning up the pool. It's been neglected for about 1.5 years and went through a flood. About nine months ago one of the contractors tried to fix the pool issues but didn't get anywhere, just wasted a bunch of chemicals. Pulled about 40 gallons of leaves and algae from the bottom. Fixed multiple clogs and leaks around the pump and replaced a broken DE grid. Cleaned the DE filter twice when back washing didn't help. Pressure jumped over 15 psi within 2 hours last time. Algae really clogs up a filter! Hosed off and soaked in Cascade dishwashing detergent twice which really helped.
Cya was above 120 (diluted the water 50% with distilled and the reading was CYA 60 since test only goes up to 100) so I did a 3/4 drain and refill. I haven't added any chemicals (before or after) until i could fix all the leaks and clogs, and remove as much leaves and algae as i can manually. CYA now reads 0, but Leslies said their test doesn't go below 25. I probably ended up draining about 7/8 of the pool.
I'm preparing to shock the pool.
FC and TC are both 0.
CH is low @ 160
TA is low @ 60
PH is 7.8 (which according to your SLAM page needs to be below 7.5)
Pho (Phosphates) are above 1000 after drain refill.
I read Pho aren't a problem until they reach over 1000 ppb. Would you correct this or let it go?
Is it worth testing for ammonia?
I've been getting my test done at Leslie's but i'm about to order a Taylor K-2006 testing kit since the water is clearing up. Are there any other tests that i need beside what is contained in the Taylor Kit or supplement with any strip tests? It looks like the reagents give the best results.
The last time I added DE, there was a slight amount returning to the pool. It wasn't much. Is this normal? The only tear i found last time was about 1/8" on the bottom of one of the grids.
Any other suggestion, pleas let me know.
