Hello everyone, Let's start a new chapter, well my old Island Reef was having a lot of problems for almost an year I was trying to fight them but I was always having STN then bubble algae attacked my rock scape and since I like everything spotless so I could not take it anymore, I decided to take down the tank and keep some of the live stock that is currently spread around LFS and friend's tanks ahah Then I also had problem with the cabinet and that needed to be replaced.., another "excuse" to move to another system ahah whoops. So I decided to build a completelly new system from scratch, with a new custom made optiwhite tank and custom made black cabinet, ideas start to come up and I decided to build an outside sump area where I can just keep all the equipment and make water changes without damaging the inside wooden floor. Not to make this post massive let's talk setup... Setup: Tank 110 x 70 x 50 cm - with an external "coast-to-coast" overflow custom made with optiwhite glass by Fragário do Norte – Propagação de corais | Propagação de corais, frags, peixes, invertebrados, produtos para aquariofilia, loja on-line Sump 50 x 50 cm - will use my current sump for now but will upgrade soon Outside sump area 180 x 70 x 90 cm - Custom made with double insulation to minimize heat loss in the winter and heat up during summer. Scape Dead rock and dead sand, my objective is to start from the beginning.
