EHEIM 2260 or FX5???

i'm sorry, but can someone explain to me what exactly "priming" does as people say the fx5 does?
how far would you have to go on modifying the fx5 in order for it to run with the best performance as ya'll are saying

primimg is basically starting a siphon form the tank to the filter and then the filter should start by itself.
just took this qute from your site make up your mind the fast flow rate on the FX5 is it a good thing or a bad thing 
This modification is good for a few things.
1. ) Increase bio media capacity. Possibly around 9-13L
(Depends on mechanical filtration and Chemical filtration volume)
2. ) Decrease flow velocity through mechanical and bio media for better filtration
3. ) Large cross section surface for flow which decreases the restriction due to media becoming dirty.
5. ) Cleaning will be even easier and you won't need to disturb the biological media at all.
6. ) Eliminate about 5 possible warn o-ring issues
7. ) Original Foam blocks don't seal as nice as I would have liked to the basket above.
8. ) Increase the time between change intervals.
9. ) Due to the decrease in flow resistance, hopefully this will help with the cavitations problem in the Fx5

About flow rates, check this reveiw out. FX5 vs 2080
FLOW RATE
Manufactuers rate their filters by the maximum produced by the pump under ideal conditions without media and things like hoses which isn'tvery helpful in the real world. Most cannisters seem to get less then 50% of their rated flow capacity when used in the real world but both these filters did better then that.
The Fluval showed a flowrate of 1991 litres per hour when full of media and connected which is about 57% of its rated pump capacity of 3500 l/ph but the Eheim did even better giving 1207 litres per hour out of its possible 1700 l/ph for a amazing 71% !
This still gives the Fluval a nearly 800 litres per hour flowrate advantage when used in real life situations but filtration is more then flow alone its also about capacity.

And what is that suppost to tell us? This doesn't mean anything. The Fx5 is able to flow at a higher head pressure. At zero head you have around 900 GPH.
The "percentage" means sqaut when you are compairing the two filters. Take a look at this. That review needs some work

You are so worthless when it comes to stuff like this.
Let me try to teach your small penut sized brain. I sware my parret has a larger brain the you.
He atleast know what to shut up.
Alright. Terms you need to know....
Volume of Fluid Flow
Velocity of Fluid Flow
Pressure vs Velocity
Aight. Let me school you, if you can teach and old fart new tricks.
Volume of Fluid Flow is the amount of fluid flowing through a device at a given time. In this case we calculate at GPH or LPH. This means the fx5 has a volume of fluid flow of 600 GPH.
Velocity of Fluid Flow is completly different. Velocity is how fast that fluid is moving through a given point. Due to the Mass Velocity of water, we like to keep the velocity HIGH when coming out of the output nozzle to create circulation.
The fluid velocity through a 1" pipe compaired to a 13" canister is COMPLETLY different @ 600 GPH. 600 GPH through a 1" pipe equals out to 49 inches per second.
600 GPH through a 13" diameter canister equals 0.29 inches per second..
The Velocity is directly relasted to pressure. Pressure is directly proportionate to velocity. A higher velocity means there is a higher pressure. We don't like high pressures restrictions in our filters do we? So to minimize this in the fx5, we widen the diameter of the cylinder to reduce the velocity which could overall increase the volume of flow if the restriction before hand was great enough.
Now...... do you understand?
BTW T1, 1262 pump is 900 GPH at zero head. Its a bit more powerful at 80watts so it has a slightly higher head pressure and will be about 140-180 GPH more than the Fx5 at the same head. through some restrictions like, bends, length of piping and a filter and you down to about where the Fx5 is....

Im glad you quoted something many have already seen. What is your point? You REALLY HAVE NO CONCEPT OF FLUID DYNAMICS DO YOU!
