Replacement DLS bio media combo pack for TRUVU AIO Aquariums
Fits the following AQUASYSTEMS: 125 H, 135 T, 180 L, 240 L, 240 H, 300 T.
This DLS combo pack includes three 10" 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.
