I had a 55 gallon freshwater with various cichlids. I snagged a 150 gallon with 30 gallon w/d & sump for $400
into which I moved my fishies. I was originally planning on selling the 55 gal but no takers on craigslist. so...I am sorta sick of going to my LFS and gazing in awe at all the saltwater fish and as such, I am thinking of doing a saltwater tank in my 55 gallon tank.
I dont know much of anything about saltwater (except anyone I've asked said it is tons more work/harder to keep) and was wondering what it entails, which differs from freshwater tanks. Obviously SALT, but beyond that, can I use the same setup I had for the freshwater tank? My filter hangs of the back, two bio wheels, etc. Anyone give me some pros and cons?
Thanks yall.
