Jack’s Magic Swimming Pool Filter Media
Jack’s Magic The Filter Fiber Stuff, 22 lb | JMFIBER22
Jack’s Magic The Filter Fiber Stuff is a super-concentrated,
biodegradable pool filter media developed as an alternative to
diatomaceous earth in compatible pressure DE filters. It requires less
than half the amount of product by weight compared with conventional DE
and can capture extremely fine suspended particles.
The fiber media can also be added to compatible sand and cartridge
filters to enhance filtration and improve water clarity. Its fine
filtration performance helps reduce the particles that can leave pool
water looking cloudy or dull even when the water chemistry is properly
balanced.
This listing is for one 22-pound bulk package containing 352 ounces of
Jack’s Magic Filter Fiber Stuff.

3 Filter Types
DE, Sand and Cartridge
What Filter Fiber Stuff Does
- Replaces DE media in compatible pressure DE filters
- Enhances filtration in sand and cartridge filters
- Captures fine suspended particles that contribute to cloudy water
- Helps produce clearer, more polished pool water
- Can extend filter runs after the initial fine-particle cleanup
Product Advantages
- Biodegradable fiber-based filter media
- Non-toxic and easier to handle than conventional DE
- Requires less than half the weight normally used with DE
- Can be applied through the pool skimmer as a slurry
- Suitable for residential and professional pool maintenance
Product Benefits
- Complete DE media alternative:
May be used instead of diatomaceous earth in compatible pressure DE
filters when applied according to Jack’s Magic directions. - Super-concentrated formula:
Requires less than half the amount by weight normally used when
charging a DE filter with conventional DE powder. - Fine-particle filtration:
Manufacturer literature states that the media can filter particles
down to approximately 2 microns. - Three-filter versatility:
Suitable for use with compatible pressure DE, cartridge and sand pool
filters. - Biodegradable material:
Designed to be safely backwashed and disposed of in accordance with
applicable state and local regulations. - Reduced filter clogging:
The fiber media is designed to support longer filter runs and reduce
clogging after the initial accumulation of very fine particles is
removed. - Large commercial package:
The 22-pound bulk size is ideal for pool service companies, commercial
properties and customers maintaining multiple filters.

Manufacturer Dosage by Filter Type
Pressure DE Filters
1 DE scoop per 12 sq. ft.
Use one DE scoop of Filter Fiber Stuff for every 12 square feet of
filter area.
Jack’s Magic gives a 60-square-foot DE filter as an example requiring
five DE scoops, or one 36-ounce package.
Cartridge Filters
3 oz. per 25 sq. ft.
Add 3 ounces by weight for every 25 square feet of cartridge filter
area.
The product is left on the cartridge while the pool operates and is
replaced after the cartridge is cleaned.
Sand Filters
3 oz. at a time
Add 3 ounces by weight at a time until filter pressure rises by
approximately 2 PSI or a maximum total of 9 ounces has been added.
The media must be backwashed from a sand filter after no more than
24 hours of operation.
Do not overdose:
Filter Fiber Stuff is highly concentrated. Adding more than the
recommended amount can cause an excessive pressure increase or reduce
water flow through the filter.
General Application Instructions
Create a Slurry Before Adding the Media
Start with a clean filter and note the clean operating pressure shown on
the pressure gauge. Measure the correct amount of Filter Fiber Stuff for
the filter type and filter area.
Mix the measured fiber into a clean bucket of pool water to create a
pourable slurry. With the circulation pump operating, slowly pour the
slurry into the pool skimmer so the media is carried into the filter.
Monitor the filter pressure and return flow during and after charging.
Clean or backwash the filter when pressure rises 10 PSI above the clean
starting pressure or when the flow returning to the pool becomes
noticeably reduced.
The first few filter runs may be shorter than expected because the fiber
media can capture finer particles that previously passed through the
filter. Filter cycles may lengthen after the accumulated fine debris is
removed from the water.
Important Product Clarifications
Filter Fiber Stuff is filtration media. It is not a sanitizer, shock,
algaecide, clarifier, phosphate remover or water-balancing chemical. It
improves the physical filtration of particles but does not replace
proper pool-water chemistry or sanitation.

Frequently Asked Questions
Is Jack’s Magic JMFIBER22 currently available?
No. The 22-pound JMFIBER22 package is sold out for the remainder of
the 2026 pool season. Additional inventory is expected for the 2027
season, subject to the manufacturer’s production schedule.
Is JMFIBER22 discontinued?
No. The product is temporarily out of stock for the season rather
than permanently discontinued. The 22-pound size is expected to
return in 2027.
What is Jack’s Magic The Filter Fiber Stuff?
It is a biodegradable fiber filtration media designed to replace DE
in compatible pressure DE filters or enhance particle filtration in
sand and cartridge filters.
Can Filter Fiber Stuff completely replace DE?
Yes. Jack’s Magic identifies the product as a complete alternative
to diatomaceous earth in compatible pressure DE filters. Follow the
Filter Fiber Stuff dosage rather than using the original DE weight.
How much fiber is needed for a DE filter?
Jack’s Magic specifies one DE scoop of Filter Fiber Stuff for every
12 square feet of filter area. A 60-square-foot pressure DE filter
requires five scoops, which the manufacturer identifies as
approximately 36 ounces.
Can Filter Fiber Stuff be used in a cartridge filter?
Yes. Use 3 ounces by weight for every 25 square feet of cartridge
filter area. Apply the media as a slurry through the skimmer while
the pump is operating.
Can Filter Fiber Stuff be used in a sand filter?
Yes. Add 3 ounces by weight at a time until the filter pressure rises
by approximately 2 PSI or until a maximum of 9 ounces has been
added. The fiber must be backwashed from the sand filter after no
more than 24 hours.
Does this product replace the sand in a sand filter?
No. The sand remains inside the filter. A small measured amount of
Filter Fiber Stuff is added through the skimmer to coat and enhance
the existing filtration bed.
Does it replace a cartridge filter element?
No. The cartridge remains installed. Filter Fiber Stuff forms a fine
filtration layer on the cartridge and must be reapplied after the
element is cleaned.
How fine does Filter Fiber Stuff filter?
Jack’s Magic manufacturer literature states that the media can
provide filtration down to approximately 2 microns under suitable
operating conditions.
Why did my filter pressure increase after adding it?
A small pressure increase is expected as the media coats the filter
and begins capturing fine debris. A rapid or excessive increase may
indicate that too much media was added or the filter was not clean
before charging.
When should the filter be cleaned?
Clean or backwash the filter when pressure rises 10 PSI above the
clean starting pressure or when return flow becomes reduced. Sand
filters must also be backwashed after no more than 24 hours when
using the fiber.
Is the 22-pound listing a case of small bags?
No. This listing is for one 22-pound bulk package containing a total
of 352 ounces of Jack’s Magic The Filter Fiber Stuff.
Not Sure How Much Filter Fiber You Need?
Identify the filter type, manufacturer model and square-foot filtration
area before calculating the correct amount of Filter Fiber Stuff.
