I personally think flow is a bit important, as I have noticed that a small amount of flow especially across the front glass, keeps algaes at bay. I ran an experiment, with two setups. Both 10 gal tanks, both had flourite substrate, both shared the same light strip (132 fixture across both tanks). Both had whisper 15s, (the little ones), and a 50 watt submersible heater. I planted Swords in both and rotilla in both. And they were right next to each other. I put a 30 GPH mini-pump in one, and that was the only difference. I used plant tabbs at the time (all I knew about back then) and each tank had 5 guppies in it (feeder guppies, gambusia). This stemmed from me trying to figure out why the front of an Eclipse three, right in front of the filter exhaust, had less algae than the rest of the tank. I had two theorys. 1. Algaes didn't really like the flow and not having a place to get a good grip on, (algae in stream beds are on porous surfaces and easier to adhere to.
2. The water out of a well maintained filter tended to be cleaner and there for less nutrients for the algae so the outlet was not a good place for algae.
I found that you get algae either way, BUT......where there was flow against the glass, Algae grew about 3 -4 times slower. Also I found that even though you really have to weight down plants, The fish seemed healther, leaner and more vibrant since they would spend the day swiming against the current.
My 20 gal planted tank has a 30 gph powerhead that points from the filter exhaust (Whisper 50) at a catty corner to the front glass and the current goes down the length of the tank. My 5 Harliquinn Rasboras Swim in the current. It has been up for 6 months, I have not scraped algae off of the glass as of yet. It is heavily planted and I inject CO2. I have 5 rasboras and one Golden Pleco (the dwarf kind) and now only one amano shrimp, (the other one got himself deceased). I have Melon Swords, Dwarf Swords, Chain Swords, Red Rotilla, Red Cacomba, java Fern and dwar anubias growing to the point I am pruning on a weekly basis.
