Perfecto (made in the US and shipped to Canada) 75 gal
, $100.00; I have one still in the box in the basement.. My mistake about the lighting, it should have been $18 to$25. Putting substrate in a bag that says aquarium on it doesn't raise the quality, just the price. Yes 2 sponge filters on a 75, will work just fine. The crud gets removed weekly with the water change, not stored in a can.
After 40 plus years in the hobby, I have come to realize that simpler (easier) is usually better, and spending money needlessly, as you you seem to recommend, is not necessary, and actually a little offensive. You are awfully cavalier with other people's money.
