Hi,

I have a small (80L) nano that is running full Zeo.
I am planning for a much larger tank and I'm very keen on the ATS concept.
I follow @Henkie's tank locally and on this forum and have chatted to him on many occasions about his ATS.

So I am confident that an ATS is an extremely attractive and completely viable option for filtration however I need to keep noise to an absolute minimum.
My current tank runs quieter than my (quiet) fridge and the hum of air pumps is something that I dont wish to have.
I don't think I will have space to do a waterfall style.

With this said I started dreaming up ways of using flow pumps to run over an horizantal grid in a box etc. and I suddenly stopped and thought I should just ask a very simple question....
If you don't use the upflow/air bubble option, is it worth modifying or should I try move on and go with Carbon dosing etc?

The tank will be SPS and relatively light bioload - small anthias, chromis etc.
I'll appreciate any input.

Thanks
