beneficial critters(spaghetti, bristle worm etc.)anything that's good for my deep sand bed. also looking for 2 maxi jet 600 t0 1200 and a uvsterilizer for my 75 gal tank
I do not believe that you really need to buy those critters out right.
However, buying a few lbs of live rock from an established tank should bring those beneficial critters to your sand bed.
Usually a friend or a near by reefer (WITHOUT MAJOR PESTS) would give you a cup of live sand and a few pieces of rubble (but live) rock for free.
I set up a 120g DSB 11mos ago. Within the first 3 monthsI got those critters just from adding FRAGS from other folks tank (just the small frag plugs and a few frags came on small sized rock).
