Hillbilly, I'm considering this setup, Setup 1...as an Ocean Clear model 354 only with a Quiet One Water Pump 6000, the pump is the cheapest in my est. for a 1506GPH rating. The tank is not drilled. I am thinking this would save me money if I attached the Ocean Clear 340 and a larger pump at a later date as I upgrade from my 125 gallon in the future. I believe this would provide adequate OVER filtration for my three silver arrowana all 1ft+. I am planning to introduce two rays once the BB is setup/cycled. Currently a Rena XP 3 is not cutting it and water changes are weekly and massive.
Richardhmc I don't know if this question helps you but thanks in advance for letting me piggy back on your thread!!
