thanks.
the last couple days i've been toying with the idea of adding a refugium. here's a sketch of the basic idea.
it will use a diy PVC continuous siphon overflow. non-surface skimming. my skimmer has a surface skimmer and i want to keep the overflow as unobtrusive as possible. the fuge will be a custom 5g tank to fit under the stand, 12x10x10". it will house a live sand bed, macro algae, a bit of rock, and maybe a seahorse or two...or maybe a seahorse and mandarin goby. it's purpose is strictly nutrient export. depending on how nice i can make the fuge look, i may very well cut my cabinet door in half, horizontally, to display the fuge.
thoughts or suggestions welcomed.
