lets say i used plex with holes drilled in it at perfect space and size. running 2 filters 1/2 deep gravel on tank bottom. would 16 inchs be enough for a jd? with blood fins on top figuring they had a way to go from top to bottom but not the jd? could i use a powerhead to blow the debri to one corner to vacuum? keep in mind just a thought at this time any ideas /suggestions are more than welcome 55g 48l 21h
