Hi. I Recently Purchased A Used 29gal Oceanic Biocube. It Came With A Crp Insump Protein Skimmer Which I Dont Know How To Use. I Also Purchased A Odysea 25o Power Head Filter. A 200watt Heater. 30lbs Live Sand And 20lbs Live Rock. The Tank Did Not Come With The Bio Balls In The Back. I Heard That Its Better To Use Live Rock. Due To Nitrate That The Bio Balls Produce. Can Some One Clarify That For Me? I Eventually Want To Make It To A Nice Looking Reef Tank With Some Small Fishes. Its Been Running For 24 Hours Now. Current Condition Seems Ok Yet The Temp. Seems A Little High. Can I Get Some Suggestions On How To Set It Up And To Maintain It. All Help Is Welcomed.
