Way back in the day (Late 70's) Reading on sewage treatment plants, I remembered how they were using ensymes to break down poop. 10 years ago I saw some at the store but the price was just too much. So I duplclated what they were selling in plexi. Once I saw that it was a basic divided box the light came on. Not complacted, and as long as you use a protien skimmer your good to go. No need for venturis. And if it works on my corals it will work on our girls.
Add a filter
Add a place for beni bac to grow.
Increase your O2 as high as you can. Then do it again!
Wash and repeat
I also think the only way you can use too much O2 would be by adding O3 to your system.
Anyone considered adding CO2 to their water to keep the PH in their prefered growing range?
I have a calicum reactor that does just that. Adds CO2 to break down arginate blah blah blah. I do understand adding too much anything is not good. But it would be simple to have the CO2 keep the PH at your desired level. With out the use of PH down or your choice of acids...
My 2 Cents
That sounds like a simple biological filter, not a refugium
. A refugium uses macroalgae, live sand (substrate) and live rock in separate sections of the sump (what you were looking at built out of Plexi) through which the water flows. Those refugia using macros, especially making big use of macros, must
use additional lighting for the macros (macroalgae in this context). The live rock houses nitrifiers and many, many other creatures, and the macros act specifically as nutrient accumulators.
If denitrification is desired, a low-flow section of sump, with appropriate anaerobic denitrifying microbes, is created as a bypass section of the refugium.
Most growers aren't using CO2 for water parameter manipulation, it's really pretty easy to keep it in range once you learn how to balance the salts (if that's how you roll) and begin with good, clean water, RO is preferred by many for this reason. If they *are* using it, it's in their sealed rooms during the daylight phase of photoperiod indoors. I believe they usually situation their reservoirs, if using reservoirs (sump for us) outside the rooms. You don't want a high CO2 level in plant root zones.
Because you use a Ca-reactor, you know what I do--that it's not that difficult to get CO3 into solution.
I agree with you regarding O3 use in reservoirs, many folks like to use them to control odor in this context.
Are you familiar with the book Natural Marine Aquarium--Reef Invertebrates?
