it makes it a lot easier to maintain water quality. More water is always easier to distribute nitrate more evenly. "The solution for pollution is dilution" is the phrase I remember hearing years agoDo extra tall aquariums help in any way in terms of territory and space for fish versus standard sized tanks with the same footprint? Like if you had a 225 over a 180 or a 90/110 over a 75 gallon would it enable you to get more fish and give your fish more territory or is it just empty gallons?
