Its "Ok", the lighting is mediocre, you would need to place the sps high up. Being a closed tank, with heat build up it will require a Chiller to stabilize the temp. The filtration, in my opinion, is not great. The skimmer is too small. Dont expect a Zeovit tank of the Month Sps tank. I would rather go for a drilled tank, with same size sump and a decent skimmer where you can run such things as bio pellet reactors etc. One thing to keep in mind is that seeing the tank is gonna be a Sps Dominant tank, it will eventually require dosing of atleast Calcium, Magnesium and Alkalinity as the sps colonies grow and so too do their demands. You will want a dosing pump dosing into your sump. Sps love lots of nutrients, "High import and high Export" and this is where a good skimmer is crucial and things such as bio pellet reactors help. Like I say, Sps can be kept in a Max 250. But it is far from optimal and the results will be dissapointing. You will struggle with coloration and they probably will just brown out.
