Hi guys This is my very first post here ... I always want to try Marine setup ( currently freshwater setup) but didnt dare to as i know that a marine tank requires chiller, good light and etc .. Just yesterday i accidentally bought a blue LED light that is suitable for a 1 feet cube tank (around $60) from Clementi ... I tried to sell it but no one is interested, so i am stuck between setting up Pico tank or put the light in the store room Currently, i have some items Red Sea Salt HOF UP Aqua PRO-LED-X-B I just want a simple tank like 2 fishes with 2 shrimps ? Maybe some simple coral if possible? I read most of the posts under this section and was amazed by the pictures ... If i am setting up a new tank, should i get a IOS tank or a 1 feet cube tank ? A skimmer maybe ? Any suggestion will do ? Thank you so much !!
