for the price of a g6 (the biggest one) here you can have two fx5's if you shop wisely.
nice little filter if your filter is on show but i have yet to meet a keeper who keeps their filter(s) on show with tanks that are on display so this would be a pointless spend.
you can buy custom a sump for far less and purchase overflows plus pipework and have a couple of hundred in change. you could DIY a sump for even less i would imagine.
it's a waste of money. geared towards the guy that needs to have all the latest high tech gadgets. the LCD panel is completely worthless and provides no useful information. for that money you can get several "real" filters, like the fx5
