Actually, I believe he is referring to aquariums with Hillstream Loaches with regard to 13.5x turnover rate. On second thought it's hard to discern from the writing quoted below whether he's referring to loaches in general or Hillstream loaches. Anyone have any input on this? What are other running for combined gpf flow in their clown aquariums?ClownLoachSharky wrote:wait, according to martin thoene, his cl aquarium has 13.5 x turnoverpolarburn wrote:Hmm. Thanks for your input ClownLoachSharky. Just re-read this article: http://www.loaches.com/articles/river-t ... old-design, and realized that the flow rate I was aiming for is actually for the Hillstream Loaches. I'll have Clowns and will probably not need as much flow.
On top of that I just realized that I was looking at circulation ratings instead of the powerhead ratings on the Maxi-Jets and will now be looking at purchasing two of the Maxi-Jet 1200's as they'll give me a combined turnover of 5 times my aquarium volume per hour versus much less of a turnover rate on the 600's I was originally looking at. I'm just wondering if this is adequate for the clowns in a 6 foot long aquarium.

"The size of power-heads one chooses to run the system depends on what type of fish one wishes to keep. This design can be used for any species of rheophilic fish, but some like more current than others. For Hillstream Loaches, who live in water flowing often at 1 metre/second we can probably never truly achieve such flows in a conventional aquarium.
I normally choose power-heads for these species that combined will move the entire capacity of the tank through themselves a minimum of 12 times per hour. As an example two Aquaclear 802s (now called the Aquaclear 70) will turn over a 65USG tank 13.5 times per hour."
