I just have it set on the lowest setting, runs through filter material and about 4lbs of live rock/sand. I guess the filter and rock slow the flow down enough, it's really not the bad.I have the same setup on my 10gal as well.

Am I correct in assuming that material is INSIDE the filter? Here is a cute one. I run a 300 with a Mini impeller. That slows it down a bit. Then I run a Mni with a 300 impeller, but it does not speed up. Must be physics thing :D

BTW that is a novel way you do things. There are those who say that a DSB less than two square feet does no good. I would think your way of biological filtration gives you more room inside the tank.

Yep the cotton fliter material is just after the output. Then i have the basket thingy :wink: filled with live rock and under that is live sand. I also have the variour types of caulerpa.

I think that refers to sustainability of sand critters for detritus/nutrient processing. Denitrification occurs on the molecular level so should still be totally viable in any tank.

Clinton,

I'm interested in what you've done with the Aquaclear 500 as a refugium. 8)

How do you change/clean the filter material? Have you got any additional light over it other than tank light? Have you rigged any thing at the exit spout to keep caulerpa, etc from flowing out? :?

That sounds like a great idea which I might try on my 10G.

Aqua Fuge 500
 

Sounds like a car race. great idea. You got me thinkin. Love your tank pics.

Cheapa, I just keep coming back to this thread, I love your tank it is so amazing, Can you please post a pic or two of your aquaclear 500 refugium so I can understand how it is set up.

Thanks, and again, simply amazing.

do you not have to be careful about maintaining water parameters in a small area?
I am going to look at the possibility of doing a nano reef. Not sure if it'd be 10 or 20 g.

I checked my water parameters for the first two months of my setup. Nothing changed really noticably, haven't checked them in almost a year. No i'll effects. I only feed every 3 days or so and i do have calurpa ect.. for nutrient export so that could have an impact. I would say it's been the easiest of the tree i've have by quite a long shot. Just my $.02 though. :smile:
