Switching from HOBs! 5
By Emily on
I've heard great things about this sponge filter and I was glad Angelfins offered both the fine and coarse sponge at a very reasonable price too. I've been making the move to switch from HOB to these with a powerhead to help increase circulation and the water remains crytal clear. It's silent compared to an HOB when the water level drops. I plan to probably a get a few more since they're so affordable as back-up or when I need it for a quarantine tank.
