Setting Up 8Ft Tank Filter Help!

[Georboo]

Hi I've bought an 94x15x25 tank :0 I've had several tanks years ago all tropical and always used the under gravel filters which actually didn't do a bad job but my largest tank was 4ft..
Question is what is the best filter to use on this one? I believe with this size external is the way to go but still so many options..
2 x external canister filters or 1 big one?
1 external and a sump? Makes? Models?
Also 2 or 3 heaters in the tank and/ or 1 in the sump?
I'm not adverse to a bit of DIY but I'm not drilling holes in glass...
Any help and advice greatly appreciated and thank you in advance.
Oh costs involved would be grand too

What do you want to keep in there? Plants? If you look for cheap and low maintenance go for Hamburg mat filter (HMF).

I really don't think a Hamburg mat filter will be good enough for an 8 foot tank.
 
You are however only talking around 130 gallons, but the 8 foot length could prove a stumbling block. I would go with an Eheim 2080 and a good strong power head  to eliminate dead spots.

2 fluval fx6, rrp £225 each, so £450 on those 2 filters
 
One filter each end, flows directed same way, but one angled more to surface for agitation.
 
Best filter ive ever bought.
