Jack's Magic The Filter Fiber Stuff (36 oz) - 1

Easy to use and it cleared up my cloudy pool water within hours

This material is very light and fluffy when removed from it's bag. It worked as described to remove the tiny sequestered metal particles after treatment although my pressure reading did not increase much at all. I have cartridge filters so I removed the filters for cleaning after a few days of circulation. The fibers formed a thick coating over the filters and removing them was a messy procedure. I pressure washed the filter cartridges and replaced them. The filter system returned to normal operation. I would not hesitate to use this material again if the need arises.

I haven't put this product in my DE filter yet, next filter clean. The bag was sliced by a sharp blade and powder was leaking. I weighed bag and it was close to the right amount so I taped it and kept it. I don't like how they make amount needed to replace the DE so complicated. Just give the amounts needed for a 48 Sq ft filter, etc.. It would be easier to provide just the weight of fiber needed for each size D.E. filter. As far as your instructions all it mentions is a D.E scoop. My D.E. scoop is 3 cups or ½ lb. of D.E. Weight of fiber is not mentioned, it would be better than guessing depending onon a scoop size. What is someone uses a coffee can?I'm not sure yet how much to put in initially and how much is needed to recharge the filter grids after a backwash. I hope I bought the right size. Make it easier where no math is needed.I will rate again after my Filter needs cleaning and I'm actually using this product. I've tried other brands and I liked them.

Clears the pool water quickly! Great stuff!

I had not heard of this product until I stumbled across it. Did a little research and decided to try it out instead of using the regular DE. It works great as promised. Had to use far less of it that DE saving money Nd its biodegradable

I read the description and the reviews and figured I would order this because it sounded great and would arrive before DE for me to use in my filter. What a mistake! I cleaned my filter, reassembled it, then added this junk according to the directions. Using this material was, by far, the worst pool decision I've made! Fortunately, it did not cause permanent damage, but it was a doozy to clean up and necessitated calling a pool guy to help get everything back in running order. Do NOT use this if you normally use DE!!!!!

I added 4 ounces to my 24’x48” above ground pool skimmer with sand filter and the water is now crystal clear. I had issues with my filter not filtering out fine particles especially when vacuuming.

Greatly improves cartridge filter filtration!
