AbbeysDad, could you explain the water bottle baffle and how to make it? Or, if you used someone else's plan, could you provide a link? I've been thinking I'd like something for my surface current, but have no idea how to go about it. Its a great idea! Many thanks!

Is there a point that one can actually go filterless? Just a powerhead for water movement and to disturb the surface for oxygen exchange?

With sufficient live plants, an aquarium does not "require" a filter. Minimal water circulation is advantageous (not everyone agrees on this) but a powerhead might be too much in smaller tanks. The optimal word is "minimal" water movement, so valuable CO2 is not needlessly driven off.

I had a 10g tank well planted, no filter, no light (sat in a bright west-facing window), just the heater. This ran for several months with fish and snails and did very well. It was an experiment. I found that the fish and plants were fine, but the water was not crystal clear, so in the end I added a small sponge filter just to circulate the water and provide removal of suspended particulate matter.

Which brings me to the issue of filter-less planted tanks. The filter in a planted tank only serves two purposes, those mentioned in the preceeding paragraph. It is not there to do any cleaning of the water, that is the job of the plants; nor for biological filtration, as that too is better handled by plants.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If youíre going to take it under your wing then youíre responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

Here's my two cents:
1) HOB's can be noisy and I don't like the cost of the cartridges.
2) I have used an Eheim Ecco. Totally silent, 9 watts to operate, not too much flow. Problem is, the darn thing is over-priced, in my opinion!
3) A sponge filter and a really small power head is totally quite. I have an aquaclear 20 and a "double" hydrosponge 20 on my 40 gallon tank. I love it and it's silent. I thought the water flow was a llittle high, so I put a piece of clear plastic tubing (from Lowes) on the outflow after drilling holes to make an underwater spraybar. I attached the "spraybar" using suction cups and clips from Big Als. Aimed it slightly up and that gave me a little surface disturbance, a very light current, with zero noise. Not too expensive ($35 for entire setup). Downside=takes a lot of internal tank space...
4) I do use some air pumps,but I hate the noise!

I might check in to a sponge filter. I'd like something that will clear the water but cut down on the current. With a powerhead it will also serve double duty to send water through my CO2 reactor.

The sponge filter idea/credit belongs to Byron, I got the idea from him, I never thought about a sponge filter on a larger tank. It's been working great so far.
