Does 3000l/h too strong for a 50gallon tank?

any1 can comment?

Wah.. 3000l is 750gal.

That means u are cycling ur tank water 15 times an hour.

I am only cycling 5 times an hour only.

isn't that more is better?

i afraid my fish can't swim freely.. have to fight the current all time

More circulation the better provided you do not put corals which require little water movement on an area with high water movement. Fish can benefit from exercising, some fishes like anthias, some species of tangs like to swim against strong currents.

yo marineman,

i only have buttons and mushrooms.. these 2 cannot take strong current rite?

Right unless you can place them in a low water movement section

thanks a lot.. must design how the water flow

Depend on your livestock, 15X may not be enough. I have 25x on my tank. But very important thing is that you don't want to create strong Laminar water flow. Water that go in one direction very strong and cause your fish to stick their back on the wall. You want turbulence, random water flow like what you experience when you go scuba diving.

But unfortunately, all power heads is creating Laminar flow. So the trick then is to put 2 power heads opposite on each other and have the water collide at the middle and thus create chaotic, random water current. This turbulence, random current is very beneficial and crucial to the health of livestocks especially Inverterbates.

For my tank, I have 4 pumps with intake at different location and have their output collide on each other thus create random current. Also, I place my power head such that the food never have the chance to settle on the sandbed, it will move around on by the strong current and it left uneaten will be filter out by my protein skimmer. This strong random current helps to keep my water quality up.

Hope that helps. there is really impossible to create too much water current compare to the nature.

the flowrate of the pump is rated based on 0 height (non presure rated)....if you are using it in sump tank, you should measure the height of the piping, usually, the flowrate will reduce trmendiously with the increase of the height as the gravity will push water back and thus reduce the flowrate.

this is how you calculate; measure the height of your pump to the main tank, if there is any elbow use, and another 1/2' for each elbow, when you get the total height, use the flowrate chart (usually provided on the box) to see what is the flowrate at the height that u measured....

you will be suprise that at ard 6'~7' the flowrate could reduce more than 1/2 if you are using those taiwanese made pump.....
