Red Sea Max RSM 250 v/s 250 D

[w00t]

I think by D people just refer to the pump change, and the two other small changes to the skimmer and glass lip at the top.

There is no such tank and if there is no one sells it are u sure said forums are not talking about red seas new 450 and 550? Just google 250d and see for yourself

I have a RSM250.

I have never heard of this 250D. There is only 130/130D.

Hope that helps
