I'm in the midst of starting a marine tank. Posting some pictures here for sharing & hoping to seek advice from more experienced reefers. I have a 3ft tank that's still in pretty good condition. Did some price checks & decided to stick with the current tank/cabinet used previously for freshwater. Add sump & overflow. Save up for a bigger tank in the years to come. Appreciate the advice from Razali (DE aquatic) so far. General equipment list : Tank : 3ft x 1.
