Opening Pool - Cloudy Water

[Sunnydaze]

Should I be backwashing the sand filter often during the Slam process?

Good rule of thumb is to backwash when the filter pressure increases 25% above the baseline of a clean filter pressure. Ie., If normally at 10psi, backwash when it reaches 12-13psi

I would also add that since you are Oklahoma, there is probably a LOT of dirt in the water. I have had a pool here for about 3 years and I had a pretty significant cloudiness issue that I *thought* might need a SLAM but my numbers showed otherwise. Ultimately, it took almost 4 days of running the filter for 24 hours straight to get it to clear back up to what I expect to see. Not saying you don't need a SLAM, just that the extreme wind we have had over the last couple of weeks hasn't helped.

Unfortunately I don’t have a pressure gauge on the filter.

Finally got it cleared up. We took a sample to the pool store and got 560 on phosphate levels. Any tips for products on the best way to bring those down?

At that low level, no reason too. We suggest if you are concerned with phosphates, which 99.99% of pool owners should not be, get your own Taylor K-1106 test kit and see what they are. There is little reason to bother if the phosphates level is below 2000-3000 ppb.

This article has a good review and what products to use if you wish to remove the phosphates.
