So here's my situation. I'm getting ready to pull the plug on a new 240 gallon tank and I need your opinions on filtration. I currently have a 90 gallon seaclear system II ( which I hate btw ) that has a built in wet dry which basically has a Hagen 801 turned sideways. In addition I'm running two XP3's and a magnum 350(carbon filled for part time use). I figure my actual tank capacity is closer to 70 gallons so with all filters running im right at about 10 x turnover, figuring about 180 gph for each filter. The tank is very stable at the current filtration level even though I'm a sucker for cichlids and plecos.

I'm a firm believer in redundancy so I like having multiple filters on my tanks. I also believe in very large , but thinner biofilters because they can stabilize any unforseen problems in the system much faster than smaller denser biofilters can. One filter has an issue, no problem because there are several others that can pull the load.






















Both of the XP3's will go on the new tank since they've been running for several years and the magnum will still be a part of the system for part time
duty, but where should I go from there? One side of me says go with a built in overflow and sump( somewhere around 65 gallons) and pump. The other side says skip the overflow and get either 2 2262's or 2 Fx5's. I really like having multiple filters, but something about the sump system is intriguing. I had a sump in my 180 saltwater system years ago and it worked great but it wasn't quite as flexible as a multi canister system could be. Granted a sump and pump properly set up could have more grunt as far as water flow goes, it seems like a muti- canister system would have the edge in mechanical filtration, which would be a bonus with cichlids and plecs.
 
I'm running 2 xp3's and a 2260 on my 240 and I'm satisfied with the but I sure wouldn't mind adding another 2260 or 2262
 
Seems like most folks round here prefer the 2262/2260 over the FX5. The price point of the Fluval is VERY interesting, but it also makes me suspicious. I can get an FX5 for about $250, so I can basically get two of those for the price of 1 2262, but I also know you get what you pay for.

That being said, lots of people say the Renas are junk, but my XP3's have been solid and have been the easiest filters ever to do maintenance on. And the Magnum is going on 15 years. Third impeller but I run nothing but carbon in that do it's kind of expected.

I've never owned a fluval canister, but I do have 2 801 powerheads that are going on 20 years of service...... Lots of food for thought. Either way, it seems like the canisters are the way to go. Sump system seems cool, but mostly unnecessary for a freshwater tank that will house lots of big waste fish.
 
Ive got a 40ish gallon sump along with a Pro3 and 2 AC110s on my 220 and it is working great, I use the sump for mechanical because I can move 1000gph, and packed the ACs and the Pro3 with a bio media. IMO you cant beat a sump for ease of maint, cost effectiveness, and overall performance, freshwater or salt.
 
Interesting. I never would have thought of using the sump as the main mech. filter. I can get a 65 sump for about$300 and a quiet one 9000 for $150 media for another $150. That's $600 bucks for filter capable of 10x alone. Pack the XP3's with nothing but bio, split the sump 50/50 for bio/mech and turn the tank almost 12x with a beast of a mech filter. Hmmmm........
