Hey guys im fairly new to the saltwater scene but i have a 8 gallon nano reef for about 6 months and know the basics....This is the thing my aunt gave me her 200 gallon tank which use to be a FW for parrot fish...she moved and gave it to me in which she sold all the fish for about 40 a piece(they where rare color and big) so now i want to convert it to saltwater what are the kinds of things i would need for that size aquarium...so should i go foward with it or will it be very expensive and just to give up....i would prolly need alot of hardware becasue it is being converted...and ps its best if i didnt need to drill anything but if you guys think it would be better choice please let me know...i been looking all over crazy coulnt find alot of info about such a big tank..thank you guys for the help!
