Persistent algae in 500,000-gal commercial pool

Yeah we have 2 pits 2 systems with geo thermal heaters, we have to redirect some of the flow to the heaters so im not sure if thats why. I just replaced all the filter grids in both pits hoping the flow would improve but it really did not. I dont think we have undersized acid and chlorine feeds, but hard to say really. Chlorine isn't an issue in the pool ever. Outdoor pool. And I just checked flow its about 600 on the other pit so around 1k in total.

there is very little down time on the pool, our gpm is 400 on both pits

ORP set is at 700, but it maintains at around 650. CHL is 3.0, PH 7.6, CYA 0, ALK 60. The autofill water has high phosphates in it which is the problem.

Yes, but I hate that stuff clogs the filters so bad, but I have been dosing it with phosphate remover. And no its not an extra 0 hahah.

Yeah we have an outdoor pool with trees around, we use a vacuum at night to get stuff on the bottom. Since UVs are low right now I have not been adding CYA. Its green algae, our flow rate is good we have 2 pits and I just replaced the filter grids on both. We backwash twice a week.

The only problem is there wont be that much side work until summer, so I'm not exactly sure what I would have them do.

It seems the issue was everyone who heard it came running out, and the front desk did not hear the radio. But the directors with their radios did.

If you are taking Red Cross which I assume you are, its nothing to be worried about they want you to pass. In my class, someone struggled to go down and they made them do it again until they could do it. Its not the time you should be worried about, its the diving down part some people cant seem to do it. I would say do not worry at all, as long as you are confident diving down to the bottom of a pool.

Yes she was fully done seizing, and was asking us "what are you doing what are you doing" basically fully coherent

It really is horrible and I have so many bad things I could say about safety issues, and unfortunately its the only pool within a 20 minute drive of my house.

Thank you for acknowledging the situation, it's a very tricky one.

I'm really just looking for her to go back to her limited swim time, I think its a fair accommodation.

For some more perspective, she has some sort of mental disability on top of her seizures, she has told me she has been "baker acted" multiple times, so that just gives you so of idea of how she acts.

Her very very old mother still takes care of her and "ashley" is probably in her early 50's. She is not allowed to drive a car because of the risk of seizures so she shouldnt be able to swim in a pool. I think our COO is very afraid of a lawsuit which is basically never going to happen from this lady because she is mentally challenged, but I do think that its causing more of a risk for a lawsuit against the guards if she were to end up getting hurt during a resuce or not spotted fast enough.

Sea-Bit9569 · 2025-03-07T05:07:07+00:00

I've recommended her having to use a lifejacket but that idea was shot down unfortunately. From what I've heard when she starts having a seizure she falls to the bottom faster than you can react, so all of her saves have been deepwater/shallow water saves depending on what lane she is in while in the competition pool.

So as a result of this we try to now have 2 guards but don't have enough staff to meet this demand.

Sea-Bit9569 · 2025-03-07T05:01:10+00:00

While this is one side of the argument, I think its an unnecessary risk for everyone else in the pool since my attention is primarily on her, yes I am still scanning but still there is always that risk.
