Fits the following AQUASYSTEMS: 75L, 100L
This DLS combo pack includes three 6" tall rolls of DLS and 3 - 15" long pre-filter pads. The combo pack is the more cost effective way to purchase your Aquasystem AIO replacement media.
*Always measure your existing DLS roll height and pre-filter length prior to ordering to be sure this combo pack is the correct one for your aquarium.
NOTE: DLS rolls should be replaced, singularly, to avoid the depletion of beneficial aerobic bacteria. Never replace all rolls at one time.
