Please help me figure out my DE filter. I think the pool guy gave me bad info.

Feels good to have a nice clean pool. Nice to hear a success story.

I am still curious. Are you weighing the amount you are using?

What's you PH level?

I'll have to check the pH level...not sure. we had the pool water checked by a pool place last week and they had me set my salt chlorine generator to shock mode and said that after that we should be good and after doing that, the water cleared right up.

I didn't weigh the amount of DE that's currently in there. There originally were about 6 scoops of DE in there. The scoops are small and each scoop weighs about 0.33lb so I have about 2 lbs in there. When I did that, the pressure was too high, so I bumped it, backwashed it, bumped it, backwashed it and after doing that, the pressure got down to normal. In other words I probably have at most 1 lb of DE in there if that.
When I actually weighed out 6 lbs of DE, it was around 29 scoops. maybe my pool isn't filtering properly since there's not enough DE...i don't know... is there a way to know that?

I ask about the PH because in the guide for the K-2006 test kit it says high PH level can lead to high pressure in the filter. How this works I don’t know but I glean that the PH level needs to be balanced.

As for proper filtering, the pressure should be around 10psi and the flow from the inlets should be fairly strong. My shallow end inlet blows all the way across my 20 foot wide pool. With the pump running it is impossible to put a fitting on the inlet fitting. Not scientific but you get the idea.

My gut feeling is the filter is clogged. I know you cleaned it already but I’d do it again. I know that filter is a bear to open with all those bolts but that’s all part of the pool game.
I opened mine one year when it was acting up and I will never forget the glorious green algae covering all my tubes.
