Your fishes must have motion sickness I guess. :hihi:I run a 2215 on my 11.4 Mr. Aqua. So I would get a 2217.
Haha. Nope. I have the double connect valve for adjusting my slow. And I'm keeping shrimp.Your fishes must have motion sickness I guess. :hihi:
Pretty much this. Heavy plant load pretty much means your tank will be fine with a filter of that size, but most people generally opt for much more flow. I personally run a 2217 on each of my 20g tanks (a long and a tall) and sometimes I wish I had more flow on the long due to the lily pipes dispersing it so much. However, your filter will mainly server for water circulation, mechanical filtration, clarification (Purigen or similar products) if you opt to use it and additional biological filtration so long as your tank is decently planted.Um, the size of the filter is more important initially. Once the tank establishes most of the filtration IMO takes place inside the tank in the form of plants, substrate and other surfaces and the filter is primarily a flow device in most tanks. A 2213 on a 40 should give you enough flow. I ran a 2213 on a 46g for 2 years without issue. Tank was nicely planted with a normal fish load and there wasn't a hint of any algae. So if you do your water changes, take care of the plants and tank you should be fine.
Yup.what size tubing is on the 2075, 16/22mm?
I second this, once your tank is established and your plants are rooted in alot of the bio filtration is done in the tank a filter is mostly useful for mechanical, almost all my filters are 90% mechanical after established and my water is perfect. your filter is fine but more flow would be nice, i have a 150 give or take gph flow on my 20 long and also have a 240 gph powerhead to supplement, dead spots are a bad thing =pUm, the size of the filter is more important initially.

I'm just not getting big flow in normal shaped tanks. Other than startup which I mentioned, I honestly have never understood the need for big flow to move ferts, co2, and heat through water a few feet. Again I have a 72g now for 3 years with a 2215 no problems. All I do is change water regularly (50% weekly), run co2, fert, trim.I could not imagine having a 2213 on a 40b. The flow would be so weak that if there were a heater inline I would be afraid only half the tank would be heated. The same goes for the co2. It is extremely important (dont know how houseofcards fulled it off) to have the co2 enriched water transported to all corners and crevices of the tank with a 2213 on a 40b that would be extremely difficult to do.
Yes, I think you can say that. I usually only enter that level via a noon-day burst. Rest of time I'm more toward low-mid light.I would bet your on the lower end of the mid-high light area, maybe your on to something?
The lower the light intensity the less important/more flexible maintaining circulation/co2 levels and just about everything else that comes to play in high tech tanks.Yes, I think you can say that. I usually only enter that level via a noon-day burst. Rest of time I'm more toward low-mid light.
