OK I have 3 freshwater tanks and 1 Salt. I have some big tanks as you can see in my sig although I to this day still have not owned a canister filter. My larger tanks are run on sumps and my 55 and 75 are run with AC 500 only. Now I want to try something new. I am buying a brand spanking new 75 gallon with probably a nice show stand. I want this to be something really nice because I have some cool ideas for it.

I was thinking of having the AC 500 again although I want to try sealing off the hood completly and not have any clutter on top of the tank. I also don't want to have a sump for this tank. So I am thinking about canisters.

Now like I said I have never used one. Although as I understand something like a xp3 only has like 400gph. Thats not enough flow for a 75 gallon is it??? its rated for a 175 gallon. My question is can you run a cichlid tank with a heavy bioload on solely a canister??? or do you need a HOB anyways to help clear the debris from the water??
 
Personally, I think an XP3 would be fine for a 75.

its not just about turnover, its also about amount of media.

the XP3 has lots and lots of room for media, and has a very powerful flow rate for a canister filter (350 gph):

mine (seen here using powernet nozzle) puts out a lot of current (as you can see) and handles the load of big fish in a 90.

IMO it would be fine, but I think you always should have two filters on a tank (one for backup) where possible..

How do suppose to accomplish this if the tank is not drilled ??
Any filter system besides internal or a bottom/back drilled tank is going to prevent this.
Why would you even want to. The tank needs to "breathe" to some extent.
IMO, multiple filters, either cans, hob's, sump/wet/dry's, etc., are not solely for current, media capacity, gph, etc., but more importantly for me, is the backup issue.
One filter bites the dust and so shall the entire tank if you don't catch it soon enough.
I have 4 on my 125, and getting ready to add a WD. The chances of all of them crapping out at the same time are astronomical (excluding a power outage, which I have made arrangements for as well).
I guess it's sort of like a security blanket for me, maybe I should just log out and go suck my thumb. :D :D :D :D
Anything outside the tank can potetially leak, even the tank itself. If you are losing sleep about it, maybe try reptiles or something non-aquatic.
 
On a 75 I'd be tempted to run the XP3 and the AC110 (500)... or two AC110's. The nice thing with the canisters is that they can be very low maintenance. However, with sponge prefilters on my AC's I have considerable cut down on filter maintenance. The prefilters keep the poop/sand/food out of the main filter.

i dont understand what "sealing off the hood completely" means. do you not want to see anything? buy or build yourself a nice canopy. even can filters have to go over the top rim to enter/exit the tank. a properly set-up sump will not leak at all unless something major happens, but that goes with every other filter made. plus with a sump you can hide your heaters in it, but i dont even have a sump but cant wait to set one up.

yes, it could leak.

but so can aquaclears. I have drained 15 gallons out of my 65 when the motor unit on my AC500 was slightly crossthreaded (unknown to me) so it can happen with ANY filter.

so I would not be too concerned.

just put it together properly and you will be okay..

^^ agreed

I guess internal filters would be the exception. But you can't worry too much, your glass can crack and...etc....
 
Only if you get a leak by not setting it up properly. You'll definitely get more sleep with a canister, knowing you are not going to get a flood. I have an XP3 on my 75G, and no other filters, with an inline heater. This eliminates the heater in the tank. Get the Hydor ETH300 if you do, it's the correct size input and output for the XP's. My 75Gis also heavily planted, and really doesn't need a filter other than for mechanical filtering. The plants to the biofiltering.
