I support MARSH sponsers, but its the relationships that are formed which I find more important. I would sooner buy from someone I know. that Even if it costs me a few more bucks.
The top 4 places I spent money last year were the following
AddictiveAquatics - Jamie is a nice guy, great family and fun to talk with. He constantly gives me a hard time!!! He has competitive prices and good service.
SapphireAquatics - Kyle makes great quality stuff, cutting edge nano skimmers, I bought nano skimmer, hob fuge, custom fuge and custom large skimmer. Kyle is always avaliable and really supports his product.
AquariumSpeciality- Scott carries the high end and is willing to call and discuss stuff on the phone even though he is not local. Scott has in stock stuff the others can only hope to drop ship.
Buckeye - Russ is the know it man of RO/DI great customer service and always willing to help.
As far as corals, normally city pets, TnT, and Fish gallery.
I wish there were more products I could get to support ADG cause they are also great guys!
