Whats the overall top external filter when it comes to price and effiency?
All opinions appreciated.
I found the Rena's seals to be unreliable, but otherwise good filters. My Eheim Ecco had two motor unit failures. First time it was eventually replaced by Eheim, second time I pressed for a refund. In the 6 months that I have had the Tetratec's the only fault I have had is the plug socket getting wet due to water spillage form a waterchange 
for me its fluval, ive been using them since i was 14years old, never had a problem, iam not 31 now![]()
