Replacement DLS bio media combo pack for TRUVU AIO Aquariums

This DLS combo pack includes three 6 in. tall rolls of DLS and 3 - 9 in. 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.
