KittenFishMom Posted February 28, 2022 Share Posted February 28, 2022 (edited) I want to try to set up one of my tanks like the tank in "The automatic guppy fry sorter!" by Bandy in the thread in "General Discussion" from Oct 29, 2020. I have a 15 gallon tank, the 2" matten filter pad, the uplift tube. I plan to put a sponge filter on each side. I am looking for advice on keeping the pad in place. I remember someone talking about it recently, but I can not find the thread. Brandy's thread says: I used the matten sponge from the 10g in this new 20g high, and made a frame out of pvc. Two things I learned as soon as I filled the tank the first time was that the matten filter and frame, while well fitted, want to float, and when a 20 high is full the glass bows just slightly, loosening the fit. I used black silicone to attach the frame to the glass. I don't see the frame in the photos. I know I am missing something. I look forward to hearing from you soon. Thanks.
