After 1.5 years, I upgraded to a 2 feet tank which bought from Clementi LFS. It is a China brand which within my budget.
My equipment upgraded to:
Tank: 60cmx53cmx36cm round corner tank
Filter: Ehiem 250 canister
Overflow: Reef Octopus overflow box
Sump: using the previous 45x30x30 tank as sump
Filter: 1 Marine pure block and poly-filter
Light: 36w Nemolight
Chiller: Hailea HC-28a (2nd hand)
Wave maker: SOBO
Skimmer: Bubble Magus QQ2 (previously use China Resun slim skimmer)
During that time, most of my marine fish and coral knowledge learn from Sea Life aquarium, the uncle and aunty share a lot of knowledge to me. And start from that time, I always explore the LFS in Singapore (FNM, a marine shop near Clementi Mosque but now no more, Ah Beng, Pinnacle Aquatics) by MRT and walking.
Damn happy seeing my fish getting a bigger space to swim.
