25K IG Vinyl liner 18x36 with deepend. Hayward super pump with sand filter.
We opened the pool last weekend and found that it was an ugly green swamp. This is the first time this has occurred for the 3 years we have been in the house. So I immediately went off to walmart and bought a TON of bleach.
The FC has been held at 20+ for the past several days (poolcalculator shows 16 for shock level), and I really still don't see a noticable improvement! Since I can't see the bottom, I have blindly vacuumed to waste, scooped, brushed, and my blue diamond has been working non stop pulling out whatever it can (which has turned out to be mainly a ton of pine needles that made it under the cover). Have even been putting the cover back on during the day to not let the algae get any sunlight.
My water test (using TFT kit) is as follows:
I have never encountered something like this before. To top it off my SWG wouldn't come back online after the off season so we've been manually adding bleach to maintain the high shock chlorine level.
At this point, if it wasn't a vinyl liner pool, I would likely just drain it all and start over as I'm so frustrated right now. Is there a way to drain all the water out of a vinyl liner pool??
