Eheim is in... well sort of

After having some issues with water clarity, we have decided to upgrade the built in AR980 filter to an external Eheim canister filter... that... and we want to get a metal halide light which won't fit with the old trickle filter..


As you can see we havn't fitted the Ehiem properly yet... just waiting for the good bacteria to be transfered to the new filter. Give it a week or two.

We have also read that Trickle filters introduce lots of oxygen into the water, which is fine, however in teh process it also gets rid of a lot of co2.
