Some pictures.. I will use mirror plexiglas to see if that helps. I used clear acrylic just to see how it works and if the splash thing is good and to see how the water will flow through the false bottom. I should not have used the 3/3 40mm.. it is too bulky.. I could also just remover the pipe with the "witlof" I don't know the english wordt for it.. the pvc lart that goes through the acrylic. Unfortunately I am struggling to find the right LED.. I have no diy led skills.
