Update;
OK, the majority comments here are saying actual tests, test strips garbage.. that's all i have right now. I'm using metric, my pool is around 115000 liters, i've been dumpin last night i used four 3.78 L jugs, the strip shows dark pink around 5ppm chlorine. Last time the pool guys were here their test shows CYA at 30. All other chems within range on their report, and my test strips align.
Dust means algae is dead right? Or do i have to buy 10 jugs and bring the total to well over 10ppm for 'death' to occur.
And at the end of the day, there's still the original vac to waste McGyverism I was hoping for left unanswered.
Original Query:
This summer has been brutal. Water temps been so high, lots of rain, pollen. Last year i didn't have to fight so hard. This year I've used multiple jugs of liquid chlorine trying to kill this beast.
I've now had the pool turn teal green to green 3 times. Twice I've knocked it back, but it keeps coming back, as though something is trying to grow, but I chlorinated just enough to keep killing it into dust but not enough to prevent it from returning. Like it's hiding in the pipes somewhere.
Anyhow, after doing a vacuum to waste twice already, I had to ponder, is there no way McGyver a DIY way of connecting the vacuum head on the telescopic wand to some sort of 'pre filter' that will trap the algae dust and just let the water continue to cycle back into the pool?
I've really tried to think of a way to turn my submersible pump into a vacuum where I could eject the water into a bucket with a skimmer sock on it to trap the fine dust.
I'm just really tired of rushing the vacuum to waste process because I'm always worried I'm going to run out of water at the skimmer, nor do I enjoy having to pay the water bill adding water back into the pool multiple times for an issue that persists.
Any thoughts or ideas are welcome.
TL;DR, Shocked, Algaecided. Need efficient way to get this dust out without constantly needing to top off the water every week.
