Current pool is 33,000 Gallons in ground gunite with a SWG - 5 years old - Using hard well water for fill. Its been a constant battle with High TA, High PH over there years and if things have gotten away from me a couple battles with Algee. I have used algaecides in the past several times with pretty good success. Anyway over the years had pretty good luck with keeping the pool in good shape until recently. I live I Lubbock, TX and while we don't have any trees close to the pool in our backyard the wind consistently blows dirt, pollen, grass clipping ect in the pool. Got some fertilizer that had phosphorus in the pool earlier this year and have been fighting a new algae bloom.
I have put a lot of chemicals into the pool over the last 5 years!!! Is there a point at which is best to drain some or all of the pool and start over?
Here is my situation now - Had a huge wind store blow tons of dirt into the pool over the weekend. So I set the pool to waste, vacuumed out the dirt which left the algae showing. I lowered the PH with MA, put in 20oz Sodium Dichlor Granuals and Two Gallons of 10% Bleach about 6:00pm. Then came inside and started doing some research on TFP.com and basically had started doing the SLAM process since yesterday afternoon. After reading over the SLAM Material and testing the water again the FC levels were dropping very fast. I used another 4 gallons of Bleach last night over the course of 3hours.
After the first dose of Granular and Bleach I started brushing the pool down with 20" steel brush and used a smaller steel brush on prominent algae areas. Ran the suction side cleaner till sand filter pressure was way above normal and back flushed late last night.
I was just using the FC and PH kits and test strips last night. This morning started using the big TF-100 Test Kit - Best recollection on test #'s from this morning were
FC - 7 - added 3 more gallons to bring it up to about 15 FC Level
TA - 110
CH - 380 I realize this is high - need to test my fill well water - not sure we can lower it without draining
CYA - 40 - will raise this once complete with SLAM
Salt - 2400 - says to add 5 bags to bring it up to 3200 - which I will do
Borates - Never used them but thing about it after radin ga few posts.
Temp - 72
Anywho water is looking better but still cloudy cannot see the main drains or vacuum in the deep end - Ran the pump with suction side cleaner all night and had to back flush again this morning. Gonna do a regular hand vacuum and back flush and retest everything again this afternoon.
I have plenty of all chemicals on hand or readily available locally if necessary.
Question is should- does everything look ok so far and just keep plugging away?? At some point should you just drain the pool and start over fresh??
Thanks in advance for any advise.
