Drilled Spray Bar - Current Loss ?

[jonny]

Hi all,

When i set up my new planted tank with sand my Eheim 2126 was blowing the sand all over the place due to the strong flow coming from the spray bar.
I set it up vertically in the left hand rear corner of my tank and drilled about ten extra holes in all directions to diffuse the flow.

I now have no visible movement of the water which obvioulsy helps with the CO2 and keeps the plants from swaying around. The intake is in the opposite corner.

My question is this......will this have any bad effect on the overall performace of the filter? Will it decrease the flow because of any lack of pressure in the spraybar? Is this a good set up?

I am asking this as i am clutching at straws becuase my ammonia is failing to drop below 0.5ppm after nearly 6 weeks of cycling.

thanks

Your pump will be operating at a fixed discharge pressure, so extra holes in the spray bar will not affect this. The only difference will be a reduction in the velocity of the water discharging from each hole, which I believe is what you were aiming for.

I can`t really help you with the cycling question because I started up with a heavily planted tank, so a cycle never occured.

Yeah like Dave said, your flow rate is the same you just have a drop in velocity at the spray bar end. In fact if anything your flow rate may increase as the pump has less pressure at the spray bar to over come.

i agree with all the above and in fact have a fluval 105 setup in the exact same way. filter works fine and you have done the right thing to the spraybar
