yeah i few more easy questions for you..
my 25g is clean. and empty.
coral sand. ?
i got a 10kg bag and i think it's ready to go into the tank, unless i need to wash it 1st.
keep in mind i wont be adding live rock, filtration or a skimmer for a while.
it'll just be the substrate, salted water and light.
should i wash the substrate? or not ?
