Matten Filter 4 Pack - 20 Gallon Long
My 20 Long has been running on the Flip Aquatics for only few days, but so far so good. The fit is perfect, the edges are sharp, clean, straight cuts. My blue diamond shrimps are zooming all over the filter looking for morsels. My only issue is that my fancy guppies have found their way through the lift tube. I believe a piece of craft plastic mesh cut to size and inserted where the exit tube connects to the elbow will solve that problem without impeding water flow too much. It worked on my 55 gallon DIY overflows to keep my small gold fish out of my King of DIY sump. Thanks Rob and Amanda! When I set up the other 3 tanks, I'll be ordering shrimp from you too!
Got these and they fit perfect every one of them. This is my second purchase of these filters now, I have 14 of them in 14 tanks and they all work wonderfully, and look to last a long time! Thx everyone!
Set these up with small submersible pumps and filtered an entire new rack of tanks with them, best filter to own that won't cost you several hundred dollars a tank.
