External Filter Question?

[evilchild]

i have an external filter Eheim 2215 i think, just put this on my 120lt tank which is over kill, lol. but have done this to get it ready to put on my bigger tank. at first i had the spray bar on straight and that made the tank like a jacuzzi, so i moved it at a slight angle so only a few of the spray bars hole's were working, the rest were underwater. i then had an idea of taking the plastic stop off the end, this made a nice flow across the top off the, like a power head.

if the outlet pipe is almost under water is this bad for the filter? i couldn't find any thing in the manual about this and i don't want to bugger my filter up?

(also i forgot to meantion that i am still running my old filter too, standard Fluval).

Should be fine, have you tried pointing it towards the glass? should take a lot of the force out of it.

I found with my eheim external, putting extra holes in the spray bar reduced the current considerably.
I also tried taking the end of the spray bar off, but found putting extra holes in much more helpful. What I did was put holes in the opposite side so that the current is directed both towards and away from the glass. Just use a low power drill, or even just a sharp knive, and carve the holes

i did try it pointing at the glass to, it was better but still a little to powerful. i'm sure the spray bar will be fine in the other tank, i think it should sit along the side so i should have a nice even flow across the water.

thanks for replys just wanted to check that it wouldn't back up or some thing.

Current is good, fish like it dont be afraid to have a strong flow.

I have several of the eheims, and all of my output spray bars are fully submerged, and I haven't had any problems at all. And yes most fish like the current, it depends on what species you have.
