| Re: new addition to the nano i have never used a MH before so i don't know what the rules and regs are. i'm not looking to have a knockout reef as i'm limited on what i can keep with seahorses. will the 70watt be enough for some zoas and leathers? i can also put the 36watt fixture that's on my 5 now to suppliment a little light. and the bulb for the MH is 20K if that makes a difference. |
