I have recently become a a member of this board and i am thoroughly enjoying the wealth of information. I'm actually thinking i have read too much. However i am currently facing a dilemma, so i was wondering if you would be able to spare some time to answer a few questions. I have found answers too many of my questions on this forum however there a still some that remain unanswered.

I have heard you saying, you are able to use a needle wheel pump to achieve an almost invisible mist. What is the most effecient needle wheel mod that you have found to achieve this result.

*cutting the impeller arms in half
*putting holes in the impeller
*using the mesh mod
*Or a combination of these.

I also read a thread on plant central discussing an external needle wheel pump using a mag drive and then the use of a spray bar to distribute the output. Is this a good method? Or do you find an internal needle wheel with a connected spray bar to be the most effecient.

I would like to keep a minimal amount of equipment in my tank so i am leaning towards external.

I really need advice. So your help would be much appreciated.

kind regards

Hard to say what is really best, since some like the mist, others not, I use 3 different methods at home myself:)

I use disc, I use the return of a sump, and I use needle wheel.

Some trade offs with each really.
