Hi everyone.
I will be getting a 145gal tank in about 2 weeks (maybe 10 days). Since I'm planning to set it up as Oscar fish tank (already adquired one 4-5" Tiguer Oscar at the LFS, waiting for his/her new home) I am aware I will need to aim to a very good/excelent filtration system.

Since I live in Santo Domingo, options are quite limited. So far I found Aquaclear 500 (for up to 100-110 gal tanks), and I figure if two of them would provide very good/excellent filtration.

I also found a wet/dry designed for 75gal, but looking at the level of complexity in installation (e.g. my tank has no holes in the bottom) I'm ruling this one out (although the idea of combining it with a HOB seems interesting).

I still have a couple of LFSs to visit and I'm running out of choices. Ordering on-line is not cost-efficient due to shipping/custom taxes (e.g. for a 7lbs book that cost me USD100, I usually end up paying around USD35 for shipping/taxes) and time of delivery (usually 2 to 3 weeks).

2 of those Aquaclear 500 filters should provide plenty of filtration for your tank.

there are variuos recomendations about how often the water in a tank should be turned over/filtered on an hourly basis as i am sure you have read. Obviuosly the more filtration, the better the water quality, and the less you have to do as far as water changes(frequency and amount) IMO, which is better for the fish. Again it depends on stocking, and the type of fish. The aquaclear is rated at 500gph and i usually subtract 10% of the GPH for filter media, etc., so 2 aquaclears should be 900gph approx. and that will give you roughly 6x. If you have a lightly stocked tank i would think that it would be sufficient. First determine the capacity of the aqaurium: lengthxdepth = xxxin2 and then factor in 48in2 per inch of body length - this gives you a rough approximation of total marine tropical fish length. Rough idea because larger fish need room to swim versus many smaller fish as a rough guide, and the bioload of the type of fish(s). Start out with a minimal number of fish and test your water, as you/if you add fish, then check your water parameters - but i would not exceed the capacity of the aquarium. Also when calculating your capacity, base it upon the full growth of whatever fish your stocking your aquarium with.
