I was wondering if this was possible and any problems that could occur except bad building. I was thinking that an external filter were possible to build with a fully enclosed bucket and pond pump. I was wondering how the suction from the top of the tank could be provided so that the same amount of water was being exchanged.
If any body how was keeping touch with the semi-automatic water changer topic I did that, all finished photos when I have finished the tank.
I'm desperately looking for a good way to make a home made DIY filter. The plan in the picture sounds great, is it possible to avoide it's disadvantages by doing this:
Adding some airstones to the bio-balls part to provide oxygen and hence getting better filtration, and replacing the siphone action by a small pump to overcome the "air tight" thing?? It would be a Canister-trickle filter!
Is it possible or is it stupid?!
In case it was possible, how strong would be the pump needed to accommodate a 325L tank??
it should work somewhat similar to a canister filter, make sure the pipe going into the filter is much larger than the one coming out, you'd be better off just buying a canister, or making a top filter,
