I decided that my 40-gallon breeder tank needed a stronger filter, so I put an aqua clear 110 filter on it. The current was way too strong, I browsed around online and seen only a few baffles but wasn't a fan of how they looked. I went to fusion 360 and came up with this minimal rainfall baffle. its length is 120mm the gap for it to clip on is 2mm. I believe this will fit any aqua clear 20-gallon and up filter. It just clips on nothing special needed, once installed the flow of the filter will slow and be forced to the backwall of the tank allowing any decorations/live plants to contribute to slowing the current down further.
