Thanks for the advice!
Will receive my tank on this saturday, more questions follow:
1. Sand. heard that there are two type of sands available, grade 0 and 1. Which type is more suitable?
2. Rocks. most of my rocks are small pcs, do i need to get a bigger one as base?
3. Water. natural sea water can speed up the cycling process, thinking of get it from LFS. If not, will do the salt mixing with tap water.
My biggest enemy for my existing nano tank (1 1/2 ft) is white spot. How do I prevent this when I add fish to my new tank next time?
