102g..............Personally, two Aqua Clear 101's and a DIY wet/dry sump(costing under $60 to build) will work for me..........If not so keen on personal construction skills, then scratch out the DIY and replace it with a FilStar Xp3................
Aqua Clear--------->Best MECHANICAL filtraion unit out there.....
FilStar Xp3-------->I have been a FLUVAL owner since the late 80's.........I have recently switched to the FilStar Xp3 because I have sen their prices slightly less than that of the FLUVAL..........The Xp3 model works just as good...........
A DIY wet/dry sumo------->Home Depot, Office Depot, and Target.........These three stores sell the components to biological filtration system that costs under $60 to build...........
