The AquaClear HOB filters are a great blank canvas but it needs a great companion like inTank. This media basket will greatly improve the clarity of your aquarium water. Everything is forced through filter floss with it’s specialized designed chamber. Water is then forced through your media. The top chamber can be used a fuge for macro algae. This is held in place and not allowed to spill over into the aquarium. the basket will fit in the filter with the lid closed.

Q: Water is flowing over the intake tube, is this normal?

A: Yes! The Media Basket forces water through media, not just up over the top like with the stock setup. It tracks water through a dedicated path which puts needed back pressure on the incoming water. This back pressure allows a certain amount of incoming water into the basket at a time. This amount depends on the type and size of media you choose to put into the basket. The filter has a built in overflow around the intake tube and water spilling over it is nothing to worry about. The filter is still circulating 100% of the water through the basket very quickly.

What Do I Need To Run This Setup?

  • As with any overflow type setup, an Auto-Top-Off system (sold separately) is required (not optional) to maintain the water level inside the overflow box. We recommenced the AUTO Aqua Smart ATO or ATO system with similar sized sensor, to be installed inside the overflow box, to keep your display water level stable from evaporation. Evaporation causes water level inside your overflow box to drop quickly and will start gurgling/bubbling as the intake suck air in, the ATO prevented this from happening.
