Hello everyone Id like to hear some input about what I should do with my HOB filter. I have a 20g tall tank and I plan on adding coral very soon. I have a 55g rated HOB filter in my tank. I feel like its pointless because I do very consistent water changes. My parameters have been spot on every other day that I check. I was hoping to either turn it into a macro algae refuge or put a couple mangroves in it or get rid of it all together. Anyone with a experience doing this in a display. Any advice would be appreciated. Thanks again.
