Heavy?

The tank came drilled - two holes on the same side. Currently one acts as a suction and the other as the discharge for my single fluval 405. The "new" discharges would be over the back and into a spray bar.

Keep in mind that canisters do not function like wet dry filters in that they will maintain the water level in an aquarium by allowing the water level in the sump to lower. Are there just holes in glass or is there an overflow box as well? If there are just holes in glass I would say it should be fine. If there's a built in over flow box then u would rethink the plan. I tried this with one of my eheims and found that if enough water would not fill the overflow box the eheim would drain it and begin to suck in nothing but air. Just something to consider.

Yes rock= heavy. Lol!

No overflows. Just holes!

then running what your talking about should work nicely.

Make sure the bulkheads are secure and best bet is to have quick disconnects or some sort of shut off valve for filter maintenance.

The problem with running cannisters through drilled bottoms is the pressure the water volume puts onto the pump, some can't handle it so you don't get the maximum effiency from them and wear sooner than the norm. Eheim is the only name I trust with doing so and only the 2250/2260/2262 models.

[barrettsline]

Eheim for the win in any situation! Eheims are all I run on my aquariums.
Quick disconnects are a must on any canister filter.

[SunnyHouTX]

I have a 2262 and an FX5 and, I got to tell ya, if the tank is bottom drilled then the canister I'd hook up to it will be the 2262

[eklikewhoa]

Personally I don't see how the two are considered in the same league.

[SunnyHouTX]

They are not. It's all about cost/benefit so ppl like me pick whatever suits them, your "opinion" notwithstanding

[eklikewhoa]

Cost/benefit... buy eheim and buy only once.

Cost/benefit... buy eheim and buy only once.

+1 on that, but I'd have to agree. It's all up to personal preference. But I love my eheims, I've only had one issue with a quick disconnect, and that was my fault.

Ok, so since my current tank is pre-drilled with two holes on the same end, how would this work? Enjoy my awesome paintshop skillz. I thought I could use the existing holes for the intakes, and then put spray bars on either back corner for the discharge, with the goal of creating some circular flow around the entire tank. Critique away...lol thanks again.

I would put both outputs on the left hand side so the two spray bars are not working against each other flow wise. Other than that.....set up looks good to go! :)

Unfortunately, looks like the "2250" and "2260" are out of production, and the 2262 wont fit in my stand!

Whats the significance of a drilled bottom that leads you to the Eheim?
