Generic Bio Floss and Bio Sponge Value Packs for Cascade 500/700/1000/12000/15000 Canister Filters (#700/1000 Bio Floss/Sponge Combo)

Sadly these don’t fit my PenPlax Elite 1000 very well. When the pads are installed in the tray over the tube, that area around the tube fits perfectly but the outer perimeter of the pad isn’t up to the edges of the tray anywhere else. There’s a 1/8 ths inch gap that lets water flow around the edge bypassing the white biomass pads and the black sponge filter too.

Works as expected. Loved the price. Disliked the bulk wrapping

Excellent media for the price

Love the bulk ordering of this. I replace 1 bio floss each month and the bio sponge every 3rd month. Absolutely positively a must for people who have Cascade external filters.

Just what I needed, Great product to keep tanks going

Seeing as you have to replace these fairly often in your canister filter, this is a great price for the amount of these that you get.

Love getting a large pack, most cost effective way to get it.

Great value!!
