DPM EP Minerals Celatom Diatomaceous Earth Pool Filter Powder

In this review of DPM EP Minerals Celatom Diatomaceous Earth, the bottom line is simple: this 25 lb DE powder is for pool and spa owners who want the clearest water with less chemical fuss. It is the go-to choice for anyone using a DE filter and wanting to remove very fine particles down to about 2 microns. The powder's long history in commercial and residential filtration means it delivers reliable clarity and helps reduce the overall need for chlorine and shock when the pool is properly balanced.

Key Features

• Celatom DE media: Provides superior water clarification by capturing particles down to 2 microns for noticeably clearer water.
• Filter efficiency: Enhances filter productivity so the system runs cleaner and can reduce chemical and disinfectant use over time.
• Trusted formula: EP Minerals' Celatom has decades of industry use, giving confidence in consistent performance for pools and spas.
• Health-minded filtration: Filters out particles associated with recreational water illness, improving overall water hygiene.
• Value pack size: The 25 lb bag supplies several recharges for most residential DE filters, offering good value for money.

Who It's For

This product is ideal for owners of DE filter systems who prioritize crystal-clear water and want a proven filter aid that removes very fine particulates. It suits medium to large residential pools and hot tubs where better filtration efficiency can reduce chemical consumption and improve swimmer comfort.

It is not aimed at owners of cartridge-only or sand-only filters unless they convert to a DE system. Also, those expecting a chemical sanitizer replacement should look elsewhere; DE improves filtration but does not replace proper pool chemistry and maintenance.
