Hey welcome to TFK! You'll find no end of great advice here.
I am no expert, and others will no doubt chip in here but I also have a fairly heavily planted 29g community tank. the surface of which is covered in floating plants, and I used to have the filter return pointing at the surface (my filter is completely housed inside the tank) this surface disturbance was reeking havoc with my small floating plants, causing them to all congregate at the intake etc. so I asked Byron, you'll meet him soon, about this similar quandary. And his advice was that surface disturbance wasn't necessary in a planted tank, and could infact drive out essential Co2 from the system which is critical for the plants. So from then on I turned it inwards so the return was just going off into the tank and not disturbing the surface AT ALL. which was lovely for my floating plants.
My concern was for the fish, that if I did not have surface disturbance they would not get the required level of O2 as the water was not being oxygenated at the surface... I forgot about the oxygen all the plants are creating but we'll brush that to one side!
I recently had a near catastrophe with a nitrite spike out of nowhere, and gasping fish at the surface looking very sorry for themselves etc. So panic stations, numerous water changes, dosing with prime etc and things stabilised. But I did turn the return from the filter back to the surface so there was disturbance. Whether this is right or not for a planted tank, at this moment in time is irrelevant as I want to ensure my fish survive. and as there was obviously something causing that nitrite spike I don't want to take any chances. maybe one day I'll point it back into the tank again, but for now my floating plants are spinning around and around on the surface, which to be honest isn't such a bad thing to look at!
I think it depends on how serious you are, if you wanted a high tech specialised planted tank with Co2 injection etc then maybe you don't want surface disturbance, but if you just have a few plants, I wouldn't worry about it. when you say the surface is dirty how do you mean??
No idea about lighting I am afraid, I am sure others will help you with this.
nice to meet you
