Hi Well I new at this. I reserching it all was wondering what is a good size tank to start with 32,50,76. ?? Long term plan I guess is a reef and fish combo tank. but to start prob.just fish and a couple small pieces of LR ?? I was told i could use a cannister type filter for just fish only tank and require a sump type system for reef setup and a skimmer etc. so any suggestions steel stand or cabnet for aquarium and or brands to stay away or to get regarding other equipment. I checked big Al's ,aqua illusions and looked at some tanks at petsmart,petcettera( sounds like this is a taboo place to others ???) just looking for idea's from some experienced .

thanks newguy
