Hi All,
I think I'm close to getting a tank that is 210-300 gallons. Convinced the hubby to crack open the savings.

It will be for 5 baby tiger oscars and possibly a pleco that I have. Depending on what size I get I may let one oscar go if needed.
I need help on deciding what kind of filtration and turnover rate I should get. Overflow set-up or closed loop? Drilled or non-drilled? What would be the ideal turnover rate? 10x or more? If you can please give me details on the reasons behind your preferences that would be great.
My experience is with a max of 55 gallons so I really need advice from experienced oscar owners who have large tanks.
Thanks in advance for all of your help!
