We just opened our pool to brown water. Late March, we got a snow storm here in NE which carried a bunch of dust from TX and NM and left behind a sheet of thick brown sediment everywhere after the brown snow melted. I’m assuming much went through our mesh cover. You can see remains on the pool coping we haven’t cleaned yet. Power washing all of our decking was already quite the job. Anyway, water temp is 56 degrees and FC at .5. Cya tested at 35 and PH at 7.4 so I started a slam adding liquid chlorine to slam level. I tested my FC a half hour later to make sure the LC and my measurements were good and then I tested again an hour after that and the level had dropped by 1 so I raised up again to slam level.

My question is, do I just slam like normal and proceed to brush and backwash? Is testing every hour and a half good or overkill. I can’t even see the bottom of the pool which has never happened before so it makes it hard to brush. Will the sand filter eventually filter this out? I also have our Aiper robot going and am going to see what the basket looks like when it’s done with its routine. Appreciate everyone’s time and advice.

Your robot will be overwhelmed. Just let the filter do it's job and backwash it when it rises 25% over it's clean pressure. You are overtesting just a little bit. At the beginning of SLAM you want to test about every two hours. As the SLAM begins to work and your FC loss begins to drop you can stretch it out a bit more. Brushing without seeing the bottom is fine. If you think there is refuse in the bottom see if you can fish it out with a net. Are you sure this dirt came to Nebraska from TX and NM? That would be blowing north and most storms don't go north.
 
Thank you. Yes, I’m sure as it was all over the news as to why our snow was brown and not white like normal 🤣 I guess they had some dust storm prior to ours and it got carried up. Weather is unpredictable around here!! I know sand filters take a bit, does it help to have my pump speed up higher at all. If you can’t tell, I’m a bit impatient. It’s never looked this bad.
