Hi Guys. I was just wondering couple of things. First, how important is water movment/flow in a planted tank. Besides my reactor and filter that is. Should I turn on my powerhead for water movement, or is that bad? Also, recently (since I turned off my power head) there has been oil building up on the surface of the water. Should I worry about this? anyway to get rid of it. I read somewhere that this happens when leaves die. I remove all the leaves I find that are dying. Any help would be appreciated.

Thanks,

Omid
 
You can run an airline for bubbles at night for a few hours...
This dissapates the surface matter so filtration can get it. Don't worry about CO2 loss at night, just run bubbles for a few hours - not all night. :)
 
I bought a ten dollar surface extractor from the LFS. It makes the filter input draw in some surface water and completely eliminates the surface scum in 10 minutes. It works with canisters and HOB filters. It is larger than the standard filter intake, but since its all black and many backgrounds are black, it is often less visible than say.. my bright green Eheim intake.

AaaaHahahah - Bight green Eheim! :D
..Just Kidding...

What company sells the surface extractor gadget?
 
:D

Hagen makes them, they are repackaged as Aquaclear or Fluval. There are some on bigalsonline.

Just do a search for surface

There's a 36 dollar Eheim one that is as bright green as the standard intake and most likely works no better than the 7 dollar AC.

I cannot say it is better or worse that the cheaper alternative, but I've been using the Eheim surface extractors for years with complete success. They don't even seem to waste any CO2.
