hi as you can see im a newbie in here. im getting a new tank this week and i have some questions about set up and filtration. im aware of the goldenrule to do three x's the filtration per hour but what would you guys suggest as being the best/ most efficient/ maintenance wise etc. also interested in the decor, substrate. i have 2" black mexican beach pebbles in my 55g and not sure to do the same in the new tank or use gravel. which is easier to clean? i have never used gravel so im clueless. in the tank will be 3 dojo loaches, 3 kenyi, 3 gold labs, 2 plecos, 2 gold severums, and 2 tiger oscars. thanks in advance for all input and advice.
