may indeed be worthwhile, but it's hard to imagine it in a 15 gal
tank. How tall is the tank? Can you lose 4-6" of your total depth to sand?
I decided to pass on a DSB
in my 30 gal
because I didn't want to lose the volume of water, and quite frankly I thought that that depth of sand in a fairly small tank looked bad. I'm going to put a DSB
/refugium in my 10 gal
sump to see if that helps (it will have to be small, though). If not, I'll use a separate 10 gal
tank sump as a DSB
standard 55 lbs LR
, 60 lb live sand, 10 gal
sump/refugium. Urchin skimmer, mag7 pump, 3 x 96W PC
combination 10,000K/actinic bulb, 2 blue LED moonlights
1.024, temp 79.5, pH 8.4
