How are we supposed to store the DE cartridge filter. I have the following DE filter (or similar), and the pool guy typically stores the cartridge within it for the winter after cleaning. This year he took it out cleaned and suggested to store it inside. I'm now confused as to what the right...

Do I need to clean before I close? AGP, details in signature. I've fallen into some bad habits lately, and had a vacation, and let things go. The pool is a mess. It's not like HORRID stuff, but it's green and the water level is low from evaporation (I'd need to add water to run the pump)...

stupidly, I added DE tonthe skimmer without the pump running. So when looked up, a cloud was forming in the pools deep end. I ran the filter for 48 hours and ran the robot several times. The water is clear but I still cant get an answer on whether it is ok to swim. The DE never settled on the...

Hello, I have a pool that is around 40 years old, and the valve handle broke clean off two years ago, and we have been looking to replace the valve, but have no idea what model we need since it is rather old, the exact same parts don't seem easy to find. I've attached pictures of my filter...

Hi all! Lotsa’ questions for ya today!!! 😂😂 I’m replacing the media in my filter (bought it used, and used it for the last two years- don’t know how long it had been since the sand was last changed). Last year I developed serious problems with staining and algae 🤦‍♀️🤦‍♀️🤦‍♀️(vinyl liner...

I had a small DE leak earlier this year in our seven year old Pentair FNS Plus. Filter elements were all original. Several had small frame cracks. No obvious fabric rips, but they were 7 years old and the I could tell the plastic was cracking. Since I had a DE leak I replaced them all. I...

I followed the guide, but even after two full cups of DE the pressure in my filter did not rise at all. The guide didn’t really indicate whether going beyond two cups was safe or not, so I have not tried any more than the two cups. Why am I not seeing any change in pressure after adding two...

New fns plus filter 48 from inyopools.com after first startup I had dirty de the color of mud throughout pool. cleaned and inspected all grids today no holes or tears. Manifold was t all the way down on manifold pipe so I greased up the o ring and it’s sitting better. recharged and now I have...

What Diatomaceous Earth (DE) should be used or avoided with DE filters? I haven't found very helpful information by googling similar questions. I tried to use food grade DE in my DE filter and quickly learned that I should probably stick to the DE that is labeled is sold for pool filtration...

I have a DE filter that looks more like a cartridge (Pentair ECDE60). Does anyone know how frequent the DE should be backwashed/filter grids cleaned? Everything I read says when the pressure gauge raises 10 PSI above normal, but my gauge is broken. My filter is so BASIC it doesn't have a...
