Is This Filter Too Powerful

I've read else where that there's no such thing as too much filtration. I think that makes perfect sense really. I'd say the only thing to concern yourself with is will the output disrupt the substrate or fish? Some fish love a strong current, others don't. There may be other concerns more experienced people might share, but that's all I can think of.
I'm not familiar with the filter you have in mind, but if it has a controller you could try it at various speeds to see what works for your tank and fish.

In which case it'll do a fine job. With careful thought and a little DIY pipe work you could work it so you don't need additional circulation from another pump. Better instead to use the filter at full capacity, distributing the water flow and kill two birds with one stone
I've read two schools of thought in filters. The first is that you tank the size rating of your filtering your case 400-1000l and divide by. This would give you the largest volume that filter is good for. So in this case the filter can handle a 200-500l tank. The other is to determine the liters per hour that your filter cycles. Ideally the minimum you would want is for 8-10 full tank volumes cycled per hour. In your case you want your filtration to move at least 2,080-2600 liters every hour. Personally, I always check the numbers for both and have yet to run into system that satisfies one requirement and not the other. As far as over filtration goes I think as long as your current is appropriate for you fish you will be fine being very over filtered. Perhaps someone knows of a unique circumstance where this is not the case but I have personally never seen one.
heh, thanks rms.
He's quite correct though in that i have a 90 litre tai with a oversized external. A tetra tec ex1200.
There are a variety of ways you can use to control flow rates.
First off, a spray bar along rear of tank about half inch under water surface pointing to front of tank and nozzles pointing towards surface of water tends to work best for me in that it creates decent water ripples for aeration and water flow.
(In fact having the spray bar above water line does the best aeration of water IMO but tends to be too noisy or too continuous water splashing noise all the time)
Next stage is to use the control valve that is on the tetra tec, one of the features of why I bought that external, is that you can control the water output flow, keep the intake flow at max but you can turn the output flow down to control water flow.
You may want to keep fairly high water flow but not to turn your tank into a washing machine!
If you find you still have too much water flow, next step would be to enlarge the nozzle holes on the spray bar, this will allow more water to come out but at a reduced flow.
Basically comes to trial and error to finding what works best for your tank set up and stocking.
I have Threadfin Rainbowfish and they do not like too much water flow so this filter setup with spray bar as above does a very decent job IMO.
So your filter choice of a Tetra Tec EX2400 for 260 litre tank is not too high or anything provided you set up suitable flow rate.
In fact I am happy to say would recommend that for you, no such thing as too much filtration but theres such as thing as too much water flow.

To be honest I think my heads about to explode. There's a Tetra Tec 2400 ten miles away at a reasonable £85. I turned to online reviews, nearly all complained about the noise of the unit, there's also a you tube video of this filter sounding like its about to take off. Currently eyeing up the APS range maybe 1400ef or 2000ef.
lol, my tetra tec ex 1200 is actually pretty quiet, no issues.
Since am deaf myself, i cannot totally vouch for quietness personally but have hearing friends come over and comment on the filter being pretty quiet when I ask them to listen for me.

That very interesting, did not realise that. wow!
wonder why the 2400 is so noisy if the 1200 is decent, would just assume 2400 is just bigger really but built exactly the same as the 1200.
Intriguing!

The aps 1400ef can apparently handle up to 600lts, and the 2000ef up to 1000lts, are these figures anyway near honest.What would be ideal lph for my 260lt. Sorry if my ??? are daft but confused would be an understatement.
I've read a lot about this filter today, problems seems to be the impellor, its the same size as the impellor on the 1200 but its having to spin twice as fast.Ch4rlie said:
These figures tend to be based on an empty filter running at full power.
So once you have filter media inside the filter the output tends to be reduced, sometimes by half or more.
Just depends on brand and types of filter media you put in.
Sorry to make it more confusing for you!
