Im starting a 90 gal
, I am using "sugar size" arragonite sand from caribsea..Most LFS
carry something, good idea to find a LFS
that you can trust but you do have to watch as some just care about selling you lots of stuff..I am gonna use a sand bed along with live rock for filtration and a good skimmer. I will also be running a 35 gal
sump/refugium underneath with a sand bed and more live rock and some chaeto algae to help with nitrates. Best advice I can give you is read, read and read more. Ive spent last 2 weeks surfing 4 different fish forums reading everything I can in the newbie sections and diy sections.. Ive ordered a Skimz skimmer my LFS
sells. Looks alot like the SWC skimmers and this is an in sump skimmer. If you are looking for hang on I have heard ther aqua c's are good.. There are lots of options for everything in this hobby..
