Difference 175MH vs 250MH

[robbyville]

You're exactly right Doug,

I think that if you already own the 175's and not the 250's I would stick with those. there's no doubt that it would be better if you were planning on SPS and Clams to go with the 250's but why buy what you already have! If you do change your mind in regards to stocking plans you could always just mount any SPs high in the tank.

If someone were buying a new system though I would definitely recommend the 250's
