Just keep it clean or it will become a nitrate collector. |
Actually you need a min. of 10x per hour not 20… It would also depend on the corals in the tank so either as a blanket statement is a lil vague… if we are talking about an SPS tank then I could see the min. 20x but considering this is a new setup thread I hope it’s not an SPS tank… for many corals that would be found in a newer tank 20x might actually be too much flow.
