Recently I did upload an interesting couple of videos showing my trickle filter innovation modification.plus a relaunch of the undergravel filter.
With the addition of Bio Home Media and its brilliant Nitrate controlling properties

Im always interested in those sorts of things, I have done some tinkering with sponge canister and hang on back filters. Where are these videos,

Eg I modified the pick up tube on this hob.
