this is my first marine attempt, trying a simple maintenance free setup
wondering if this concept is doable
30cm cube tank, thickness 4mm, with high flow rate hang on filter
sand, rocks etc etc, some simple scaping
add seawater and cycle the tank
lastly introduce a clown fish, the one and only fauna in my tank
water temperature range from 18-21 degree
20% water change, once a week
is lighting necessary? if so how many watt is require? what colour is preferred?
what else can i use for scaping beside rocks? are corals and live rocks recommended for beginners like me?
thanks in advance
