No worry’s then, I was thinking you had a diffuser. You’ll have great gas distribution throughout tank.
Stagnant areas of tank are always problematic. Not just for plants but for distribution of gases around tank. It keeps debris in motion so they get picked up and a good high->low flow ensures gases are pushed down to substrate level where micro-currents of oxygenated water are pushed into substrate making sure aerobic bacteria there fluorish. Plants also uptake co2 at roots and use that carbon for various nutrient uptake and transport functions.
So I just read an interesting page that brought up a lot of questions, & maybe some answers, too. I'll include the link at the bottom.
So, in this article it is talking about the surface agitation, O2, and CO2. With that I had no spray bar, and my outflow pointed at 45°~60° from the far top left, and inlet on the bottom right. Because of this, could I have not been getting enough oxygen low enough, and more, or less, been suffocating my shrimp?
Also, towards the end of the article, it talks about getting a surface skimmer, because if you have any surface film it will completely inhibit oxygen exchange. I don't why that never crossed my mind, but my tank does build up a surface film fairly quickly. So, would you all suggest that I get a surface skimmer? If yes, what would your suggestions be?
With a lot more thought on surface agitation and circulation, what would be your suggestions on the amount of surface agitation? Tiny ripple? Medium ripple? Let me know.
The last part of this: on here (can't remember without going back) someone suggested I put the spray bars on with the outer forward and up for agitation & circulation, then the middle two pointed backwards to get co2 dispersion behind the plants. Well, only three spray bars will fit in, so I have the outer two pointed forward and a little up, then the middle one point straight backwards. Will that have the same effect? Also, will the one pointing backwards interfere with the tanks circulation?
Let me know guys, and again, thank you.
