Innovative Marine does make some nice looking tanks. No doubt.
I have a Red Sea Max 250 with a few additions and modifications.
The reason we got the RSM was the canopy.
There's a love/hate with it.
I sort of like the open top design but...I've got fish that would love to become pro carpet surfers as well as two cats that would take up scuba diving if given the chance.
The canopy holds in heat but at the same time, the RSM is pretty well ventilated while the T5s are running.
My wife picked out the RSM while I was looking/researching them. Surprised me that we were thinking the same thing at the same time. Seldom happens.
Anyway, she likes the look of the tank and the fact that almost all of the gear & plumbing is "out of sight". Neither of of us like seeing all the BS in the tank.
I had to put a chiller on mine. My chiller connects to the back (as designed by Red Sea) and drops about 14 feet below into the basement. This helps keep the noise and extra heat out of the living room.
I'm pretty sure the Innovative Marine have a glass top but...you'll want to confirm just in case you want to keep creatures in or out of the tank.
