Plans For a 4ft tank...

[Terryz_]

had that idea a while back...exp reefers advised against it as it will damage the propeller inside

putting it near mid-tank will create sandstorm liaoz.....better place it higher

Oh...

[Terryz_]

CAn someone advise which is better... 3 x 150w MH or 2 x 250w...

[CalciumReef]

Go for 2 x 250w.Higher intensity

I suggest if your going to use the I~Ref, i recommend you use Miracle Mud. I'm using 15lbs and I got over 25 fishes in my 422 and the Nitrates and Nitrites are ZERO! Could be other factors involved but it worked for me

[Ian]

just like CalciumReef says. Go for 2 x 250w!

[Terryz_]

Is the effect temporary only or will last a long time... Okaie.... will go for 2 x 250w...
