Hi, I'm looking to improve my filtration. I have a 20 gallon long without plumbing. I have a decent amount of live rock, deep sand bed (for goby), power head and hang on back filter. The fish and ricordea are doing just fine but I feel that the filtration could be improved.
Do any of you use just a protein skimmer instead of hob filter? If so, which would you recommend? I need a small profile given space constraints. thanks
