inTank™ Aquaclear AC70 Media Basket

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.

  • As with any overflow box style setup, an Auto-Top-Off system (sold separately) is essential to maintaining a stable water level inside the overflow box. Evaporation causes water level inside your overflow box to drop and will start gurgling when it lose siphon, the ATO prevents this by automatically top off with fresh water. You can opt to manually topping off every few hours but an ATO makes life so much easier.

  1. PD

    What I love about the AquaClear 70 is the lack of proprietary cartridges like the vast majority of other filters force you to use. I can put whatever I want inside the basket and it more or less works. I had seen a video from Inappropriate Reefer where he modified the basket to make the 70 into a refugium with chaeto. I liked the idea, but didn’t really like the way he went about. With this awesomely designed little insert, I now have a hang on the back refugium that can also fit a small amount of mechanical and biological media. Obliviously a light is also needed, but so far, this design works well. Also, the over flow box is a God-send. Surface skimming keeps that oil slick from building up despite the protein skimmer’s best efforts. To anyone using an AquaClear 70 on their reef tank, I’d recommend this kit, whether it is for a refugium build or just better media organization.
